[[Hisao]] first encounters [[Emi]] on his third day at Yamaku while going to lunch (with either [[Lilly]] and [[Hanako]] or [[Shizune]] and [[Misha]]). Emi crashes into him while running in the corridors and nearly causes Hisao to have a heart attack. He encounters Emi a few days later at the track for light exercise as per the [[Nurse]]'s instructions. On the second attempt Hisao overexerts himself and has another heart murmur, inciting Emi to take him to the Nurse who reprimands both of them for carelessness, making Emi well aware of Hisao's arrhythmia. In apology Emi invites Hisao to the roof for lunch with her and [[Rin]].
Over the next two days Hisao and Emi help Rin with painting her mural for the festival and Emi invites Hisao to be her running partner in the mornings, to which he agrees. On the day of the festival Hisao is caught buying fried food from one the stalls by Emi, who insists that he eat healthy. She then ends up dragging him, and later Rin after stopping by her mural, around the festival for the rest of the day. Hisao manages to slip away and buy something sweet in the end before retiring to his dorm room for homework.

[[File:1Form.png|thumb|Act 2: Form]]Hisao arrives for his first morning run with Emi, resulting in her winning a bet with Rin. The two run a mile around the track and to Hisao's surprise he doesn't feel so bad when it's complete, beyond tired that is, his first runner's high. Emi invites him to lunch on the rooftop again and Hisao watches Emi and Rin have an argument about perspective, predictability and time travel. Upon his return to class Misha ruthlessly teases Hisao about his 'rendezvous' with Rin and Emi. Class ends and Hisao gives up halfway through his homework and decides instead to go see Emi at the track.

After the, now traditional teasing greetings, Hisao asks Emi about her friendship with Rin. Emi doesn't seem to understand it herself but it seems that the two have one crucial commonality, they work hard at what they like, what they shouldn't be able to do. Hisao also learns that Emi started running because her father was one revealing a brief moment of melancholy. Emi returns to her training and reminds Hisao to come tomorrow for morning run. Hisao is unable to sleep and decides to go for a walk in the wee hours of the morning. Eventually he falls asleep on the bleachers, waking only when Emi finds him. Today's run is even harder for Hisao but Emi snaps at him when he considers giving up. Afterwards she says that she can't stand the notion of giving in. Later that morning in the nurses office Hisao learns that before he worked at Yamaku the Nurse was one of the doctors who helped Emi recover after the car accident that cost her both legs. Sheer determination enabled her to complete years of convalescence in one years time. The two know each other well and have a friendly relationship.
==Synopsis==
=== [[Act 1 - Life Expectancy]]===
[[File:Emi knockeddown large.jpg|thumb|Emi after crashing into [[Hisao Nakai]]|196x196px]]Emi is running in the halls and crashes into [[Hisao Nakai]]. At first, Hisao is scared for his heart, remembering his cardiologist's warning to "not get hit in the chest". She apologizes profusely and then runs off again. Later, the Nurse confronts Hisao about his lack of exercise. Hisao asks him how he knows and he confesses to using "a spy" (who is later revealed to be Emi) to keep tabs on him.
The day of the track meet arrives and Hisao attends, (another loss for Rin) and meets Emi's mother, [[Meiko|Meiko Ibarazaki]]. After introductions, (and teasing), the trio watch Emi run her events. Hisao had glimpsed it before during their runs but he finally gets a good look at "Emi at her Emiest" as Rin puts it. Hisao also begins to notice that Emi appears beautiful to him when she runs and that he might be growing attracted to her. Mrs. Ibarazaki leaves mid-way and Rin and Hisao notice Emi stumble on the final event, suggesting that she's in pain. She still wins and as they congratulate her, Emi invites Hisao to join her and Rin for a celebration later in the week, reminding him to be bright and early for their run as usual. A few days later Hisao is with the Nurse due to mild chest pain as the result of neglecting his medications. As he advises Hisao to take it easy for a few days the nurse lets slip that Hisao's running with Emi means more to her then he may have realized. In the hall an agitated Emi babbles worriedly about Hisao until he surprises her with a hug and some reassurance. The dangerously tender moment is interrupted by the grinning Nurse.
Early in the morning, Hisao goes to the track to jog and finds Emi. If Hisao agrees to go running, he meets Emi at the track again and goes for a jog. She provokes him into a race, but he gets a heart murmur and collapses. Emi helps him to the nurse, where she gets a talking-to. Emi invites him to lunch to make up for it. Hisao joins Emi and Rin on the roof. Emi talks non-stop while Rin says little in her quasi-stoic way.
During lunch Hisao, Emi and Rin discuss the future. Hisao has no clear idea of his own and he and Rin are highly amused with Emi's desire to be a pirate. Hisao is quite conscious of Emi throughout and it appears that Rin has noticed this. Upon his return to the classroom he must endure Misha's teasing yet again and is informed that the Student Council left something for him in his room. As class resumes Hisao, analyzing Rin's words wonders briefly if Emi might share his growing feelings for her. After class he bumps into [[Kenji]] outside his room. Kenji advises him to stay off the roof in case the 'limbless wonders' decide to assassinate him by throwing him from the roof, and asks him for 500 yen. After he has gone Hisao finds a letter in his room. It's from [[Iwanako]], an apology for those final awkward, uncommunicative weeks in the hospital. Hisao, who hasn't thought of the hospital in weeks, crumples the letter and throws it away.
On the day before the festival, Emi grabs Hisao and uses him for help getting art supplies for Rin, who is still working on the mural. She runs out of Prussian Blue paint and either Emi goes alone to fetch some, or she takes Hisao with her. If the latter, Emi gets Hisao to agree to a physical training regimen with her.
===[[Act 2 - Form]]===
[[File:1Form.png|thumb]]
Hisao and Emi continue their morning runs, growing closer each day. As the days go on, he notices she seems like a different person when she runs. At lunch she shows her goofiness, but on the track she shows her stubborn persistence. This comes to a head at her track meet. He sits between Rin and Emi's mother, Meiko, and sees Emi at her "Emiest" (as Rin says). As he's struck by how beautiful she is, he realizes he is falling in love with her. The next day, on a rest from training, Emi takes Rin and Hisao on a picnic. Though Rin and Hisao try to warn her, it rains. They escape into the Shanghai where they have tea and cake instead.
The afternoon of Hisao's picnic with Emi and Rin starts off bad with overcast sky's and gets worse when the heavens open up, much to Emi's anger. The trio take shelter at the Shanghai where Hisao encounters [[Yuuko]] for the second time. As Hisao and Emi enjoy some cake Hisao learns that sometimes she comes here with the [[Track Team Captain|track team captain]] for discussions, although Emi seems nervous explaining it. The trio walk back to school when the rain stops. Despite previous claims that today's an off day Emi decides to run laps at the school, Hisao can either stay quiet or offer to run with Emi, in which case she sternly tells him to rest. The rain picks up on their return but Emi goes for her run anyway. Inside the dorms Hisao bumps into Kenji carrying a stack of books. After some rambling on Kenji's part Hisao lets slip that he went to the Shanghai with Emi and Rin, and receives a vehement lecture never to go again if he want's to avoid some horrible fate at the hands of the feminists! The next day Emi doesn't show up and a worried Hisao learns from the Nurse that she is sick in bed. Hisao resolves to see her after classes end. The day drags by monotonously, the only interesting moments: Yuuko looking for a stolen book, and meeting Lilly, who asks after Emi's well being.
The next day, Emi does not show up for the morning run, Hisao tries to find out, while people like Lilly and Misha tease him about how much time they've been spending together. The nurse tells him she caught a cold from the rain. Hisao drops by her room after class. For the first time he sees her without her prosthetic legs.
Finally when class ends Hisao looks in on Emi, for some reason or other the two get into a pillow fight and a compromising position. The two enjoy a companionable time as Hisao tells Emi about the days events, until she falls asleep that is. Unable to escape Hisao watches as Emi experiences a nightmare before waking her up out of it. Emi is reluctant to talk about it and Hisao decides to leave. Before he does, assures Emi that if she ever wants to talk about anything, he's there. Only now does Hisao realize that he developed romantic feelings for Emi, but he is afraid of ruining their friendship as well as feeling inadequate alongside the track captain, who he perceives as a rival. The next day Hisao resolves to find out whether or not Emi and the track captain are dating. He can't ask Emi or Rin of course so he decides to try the Nurse. After their morning run Hisao notices that Emi is a little preoccupied with something, most likely the previous night, but Emi refuses to elaborate. At the Nurses office Hisao makes a few oblique enquiries of the nurse and is happy to hear that Emi will never date the track captain, although how the Nurse knows this is puzzling.
In typical Emi fashion, they tease each other until the flirtations evolve into a pillow fight, where Hisao ends up on top of her. A moment of paralysis occurs where Hisao can't figure out whether Emi wants him to go further. They stop. After a little more conversation, she falls asleep in Hisao's arms. Hisao is quite content, until Emi begins to have a nightmare. When she cries out "Dad!" Hisao wakes her up, but Emi says she does not remember her dream.
Later Hisao finds himself alone with Emi on the roof during lunch, as she unknowingly transmitted her cold to Rin. After the usual teasing openings Hisao begins looking for an opportunity to ask Emi out. Emi is suddenly troubled by a memory of her deceased father, reluctantly she reveals that the nightmare from last night is a fairly recurring instance and is depressed by that. Hisao embraces her, reaffirming his promise to be there for her. There is a short interlude of talk about the future and suddenly Emi tells Hisao that if he wants to kiss her he should do it before the bell rings for class. There is a stunned silence, then Emi admits that she has a crush on Hisao and the two kiss. The kiss lasts until the bell rings and Emi invites Hisao to dinner after practice, giving him one more kiss in the hall before they part ways. Misha teases Hisao but he doesn't care.
Emi seems fine the next morning. Hisao contemplates confessing his feelings, but feels stymied by Emi's track captain, who often talks to her. The nurse laughs, and assures Hisao that nether is interested in each other romantically. Alone at lunch on the roof (since Emi gave Rin her cold), Emi admits that she has nightmares quite often. In typical Emi fashion, she prompts Hisao to kiss her, admitting she has a bit of a crush. They do. When he returns to class, Misha teases him about it, but for the first time, Hisao's heart feels light.
===[[Act 3 - Perspective]]===
[[File:2Perspective.png|thumb]]
Hisao takes Emi on their first date -- a picnic in the park. On their way back, Emi stumbles, the same way as she did in the track meet. In the morning, she again collapses during her run, but refuses to tell Hisao what's wrong even as he presses her. Hisao tries to offer support, since clearly something is bothering her both mentally and physically. But she pushes him away.
==Act 3 ~ Perspective==
One day, while Hisao is at the library, Emi calls him via the reference desk phone, asking him to come immediately. Hisao rushes to her dorm where Emi is in a wheelchair. Her leg has gotten an infection from overuse, which caused the stumbling and pain. She is frustrated at not being able to run, but resolved, as this is not her first time in a wheelchair. When Hisao comes to visit, their flirtations turn into wrestling. And for the first time, they consummate their relationship.
[[File:2Perspective.png|thumb|left|Act 3: Perspective]]Class passes quickly for Hisao who is eager to go on his first date with Emi. [[Mutou]] asks Hisao some questions after class about future plans and suggests forming a "science club". He gives Hisao 'A Brief History of Time' book to read and Hisao returns to his room and promptly falls asleep. Fortunately he awakes with enough time left to prepare and meets Emi at the track. With neither one having any clear plan, they grab some food from the convenience store and eating in the park. Although Emi remarks that it's not much different from what they would have done as friends, the pair enjoy a few flirtatious moments and Hisao returns to the dorms well satisfied. Only then does he notice Emi favoring her left leg. Emi waves it off and Hisao is left vaguely disturbed by Emi's reluctance. The next morning run goes well but Emi stumbles in pain immediately after and a concerned Hisao takes her to the Nurses office. Emi fobs off the visit claiming other things to do.
Both Hisao and the Nurse recognize that she's hiding her pain and the Nurse tells Hisao to make sure that Emi sees him later. During lunch on the rooftop Hisao teasingly, but firmly enforces the Nurses command and Emi reluctantly agrees. Emi and Hisao kiss goodbye before going to their respective classes and Hisao receives a scolding from Shizune and Misha against public displays of affection. Mutou and Hisao meets for a second Science Club meeting and Mutou suggests that a true scientist should look at any problem or question from more than one angle, in order to find a solution. Hisao takes this saying to heart, thinking that it might help him overcome the distance he feels between himself and Emi.
The next morning, though Emi can't run, she shows up at the track. They both steal away into a storage shed and get the idea to try anal sex. The experiment is... less than successful, and both end up feeling awkward and sore. Hisao returns to his room and sleeps until lunch. Emi comes by to see him and tells him they need to stop seeing each other so often, given that she needs to concentrate on exams. Hisao agrees, since he can still see her at the track and at lunch.
With nothing else to do Hisao goes to the library where Yuuko confides that she is on the trail of the person who stole the missing books, although she has yet to determine who it is. The conversation is interrupted by an urgent phone call from Emi and Hisao rushes to her room to find Emi in a wheelchair. It turns out that she developed an infection and has to avoid running for a few weeks. Hisao attempts to cheer her up with varying degrees of success and he notice that, yet again, Emi is maintaining some kind of distance from him. However the mood lightens and yet another pillow fight turns into love-making. This is rudely interrupted by Rin who, seemingly utterly oblivious of Hisao and Emi's nudity, wants to watch a cloud from Emi's window, but leaves disappointed when the cloud changes shape. Hisao and Emi laugh and Hisao returns to his room.
But Emi's condition is getting worse, not better. She says nothing to Hisao on the track and spaces out during lunch. After exams are over, Hisao confronts her about why she won't talk to him about it. Emi admits that, because the accident ripped everything away from her, she would never let that happen again.. Hisao leaves, feeling heartbroken that Emi will never let him get close to her. If Hisao asks Mutou and the nurse, Emi surprisingly invites him to dinner at her mother's house. Though nervous, they make amiable conversation until Mrs. Ibarazaki brings up the subject of Emi's father. Emi retreats to the bathroom.
The next day Emi arrives in her wheelchair while Hisao prepares for his morning run. Emi insists that she needs gloves from the track shed to exercise in her wheelchair and Hisao realizes too late that this is just a ruse to spend some intimate time with him. Hisao discovers a tube of lubricant revealed to be the track captain's, who is revealed by Emi to be gay. Hesitantly the pair engage in a sexual experiment that is less than successful and both resolve never to do it again. Worn out, Hisao naps until awoken by Kenji who is convinced that the cause of Hisao's exhaustion is that Emi knocked him out. Emi visits later and informs a startled Hisao that they need to stop seeing each other until after exams, Emi claiming that their current intimacy will be a distraction.
If Hisao pursued her, Emi gets even angrier at Hisao and demands that he leave. Later at school, Misha tries to offer advice. If Hisao allows it, she tells him he needs to apologize to her. He does so in a tearful reunion on the track. (Otherwise, Emi tells Hisao that it's over and the game ends.) Appealing to her determinedness, citing examples of how she made sure he was at the track and created a dietary plan, Emi gives in. She tells him she needs time to think... but to show up for their morning run tomorrow.
On the day before the exams Hisao finds himself in the library again, thinking about how the exams have been taking their toll despite even starting, and how Hisao feels about the exams themselves. He then hopes that his relationship with Emi would improve but also worries about some moments where Emi has displayed anxiety and evasion. However before he continues on he gets startled by Yuuko who has claimed to have found the identity of the Yamaku Cat Burglar, the person who has been stealing library books. After changing subjects, Hisao asks Yuuko for advice for his relationship with Emi and how she's been avoiding serious questions. Yuuko suggests that he just needs to confront her about it and prevent her from changing subjects, in which Hisao decides to do.
If Hisao talked to Emi's mother, Meiko talks about how Emi tries to believe that the accident "wasn't a big deal", but -- keeping to Emi's promise -- tells him no details. Emi overhears and demands Hisao leave while she accuses her mother of breaking her promise. Meiko denies it, but Hisao acquiesces to go. Emi immediately regrets kicking him out, but Hisao knows if he stayed, it would only cause more pain. He returns to his dorm where he reads over a letter from Iwanako, the girl from his school before his heart attack, and wonders if he's giving up on happiness.
===[[Act 4 - Motion]]===
[[File:3Motion.png|thumb]]
Hisao manages to apologize to Emi, saying that he won't stop trying to help her, not even if they break up (which Emi half-heartedly attempts to do) because he cares about her too much. Emi begins to cry and asks why he's trying so hard to help. Hisao says "because I love you." That seems to get through to Emi, as she finally breaks down in Hisao's arms. She asks him to come back to her house tomorrow, so she has time to "do this properly" and think about what she needs to say.
After the exams finished, Hisao wondered how Emi did before being approached by Mutou who starts discussing scientific philosophies with Hisao. The discussion ends with Mutou giving advice to Hisao, then commending him for making it through the exams. Before heading back to his room, Hisao begins to ponder about Emi again. Back in his room, Hisao continues to think on the reactions of Emi and how he should act. Suddenly someone knocks on his door, turning out to be Kenji. They engage in a typical conversation before Hisao heads to Emi's room. Once Hisao heads to Emi's room he knocks on the door, only to hear a choked up response. Instantly Hisao knows she has been crying. Emi invites Hisao inside and the two do a long kiss, only to have Hisao end it by saying that they need to talk. Hisao then proceeds to the bed where he puts his arm around Emi and just sits there for a little bit. Then he starts to talk about how she really needs to start opening up to him, because it will help her feel better about whatever is bothering her. Emi then says that she can't allow him to know anything that personal, that if she tells him she will have to rely on him, the two then get into an argument and it ends with Hisao leaving her dorm. The next day Hisao meets Emi at the track for their daily run. Once they finish they head to the nurse's office. Emi gets checked out, kisses Hisao on her way out and runs off to her dorm. Hisao then goes to see the nurse. The nurse starts talking about how Emi has rubbed off onto Hisao and not in a good way (Jokingly). Hisao only responds with a frown. The nurse seems confused with his response. Before the nurse can say anything Emi comes back in and asks Hisao to join her at her mom's house for lunch. Emi and Hisao take the bus to Emi's moms. When they get off the bus for the first time Emi mentions her Dad to Hisao only briefly. They then walk to her moms house. Once inside they talk over lunch and Emi's mom asks Emi if she will be visiting her dad this year, this makes Emi tear up and she quickly covers it up by bringing Rin's mural up. Meiko waves it off. Emi then says she needs to go to the restroom, Hisao knowing she is not going to the restroom follows her, soon to found out that she in fact did not go to the restroom, but to the kitchen. Emi then says for him to leave she wants to be alone, Hisao doesn't listen and presses Emi on and on to tell her what is eating her up. Soon enough Hisao oversteps his boundaries and says that Emi needs his help. Emi, furiously yells at Hisao and it ends up with him being kicked out of her house. Hisao then goes back to Yamaku and does not talk to Emi anymore.
The next day, Hisao and Emi take the bus to her mother's, but all she'll say is they are going to meet her Dad today. They eat lunch and then drive somewhere. They stop at a graveyard where Meiko stays behind and Emi leads him further in. Hisao contemplates his mortality among these gravestones until they stop at one in particular. Emi starts confessing things about herself -- that she doesn't like pink, that she's not as popular as everyone thinks -- and that the accident that took her legs also killed her dad. And as a result, she resolved to stop worrying about the future, because there's nothing you can do about it. Until she met Hisao, who she couldn't keep at a distance anymore. Now she realizes if she is going to live in the moment, she doesn't have to do it alone.
If Hisao stays after class to talk to Mutou the two will talk about science and if you can't observe something one way, then you have to observe the things it affects. Hisao and Mutou talk more about it until calling it a day. the next day Hisao meets Emi at the track finishes their run and heads out to the nurse. Emi gets checked by the nurse, gives Hisao a kiss and then runs off to the showers. Hisao then goes to the nurse to do the everyday ritual of checking his heartbeat, The nurse brings up Emi's name and Hisao can't help but frown a bit, the nurse seems to be baffled by Hisao's response to her name. Hisao then starts to tell the nurse what is going on, but the nurse cuts him off, and says exactly what Hisao was about to say, how Emi won't tell him what is going on and won't let him in close. Hisao is confused about how the nurse knows that, the nurse just says that he has known Emi for a long time and is like this about the same time every year. The nurse then tries to offer advice to Hisao if Hisao accepts the advice the nurse tells Hisao that the anniversary of her accident is approaching and she gets very depressed when it comes around, Hisao tries to press more out of the nurse, but the nurse doesn't budge. Hisao is about to say more but then Emi knocks at the door, she comes in and invites Hisao to her mothers house for dinner. Hisao accepts, goes back to his dorm and gets ready to meet Emi at the bus stop. The two leave the bus and Emi leads the way to her house. Meiko greets Hisao and Emi at the door and invites them inside. The group starts to to eat, Meiko then brings up Emi's father asking Emi if she is going to visit him this year. Emi not expecting the question avoids it and asks her mother if she noticed Rin's mural. Meiko looks confused and says that she didn't pay any mind to the painting. Emi then says she needs to go to the bathroom and leaves, both Hisao and Meiko know that Emi is not going to the bathroom and then Hisao has a choice to go after Emi or stay and talk to Emi's mom. If Hisao choses to go after Emi the two get into an argument which leads Hisao getting kicked out, and on the path to the bad ending.
When they return to the dorm, before they separate, Emi grabs Hisao. She asks him not to leave. Hisao doesn't care what context she's talking about, he says "of course". The two make love and fall asleep together. In the morning, Hisao thinks about how close they are now. That no matter what happens, as long as Emi's around, he'll be okay.
Hisao stops going to the morning runs and whenever he sees Emi, he hides, He stops going to the roof to eat lunch, if he does go to the roof it is by himself. Soon Misha confronts him and asks him what is going on between him and Emi. Hisao chooses to tell Misha what is wrong, she says Hisao is stupid and needs to go say he is sorry to Emi and tell her how much he cares about her. Hisao goes the track to see Emi running. She quickly talks to Hisao, saying she forgives him and runs off. Hisao calls to her, but she doesn't hear him. Hisao chases after her and catches up to her, but starts to wince in pain. She looks compassionate for a split second, until returning to being mad. She tells him to go away and they are over. Hisao fights back and earns another chance with her. She says to meet her at the track in the morning to do their morning run.
===Bad Ending===
If Hisao chooses to drop it and not tell Misha, she convinces him to go and talk to Emi after school. Hisao meets Emi at the track and starts to talk to her, and he says that he sorry for what happened at her house, and feels bad. Emi shows no sign of compassion. Only saying, "Whatever, I forgive you." and starts to run off. Hisao calls her back, and she is mad. She says how they are done, and not right for each other. Hisao tries to fight it, but loses to Emi. Hisao goes back to his dorm and realizes that him and Emi are done. He goes to sleep, ending their relationship forever.
===Alternative Path===
If Hisao chooses to stay and talk to Misha instead of going after Emi, Meiko will apologize for what just happened and that she should have known that Emi is going to be very touchy about this situation. Meiko continues talk to Hisao about the accident and that Emi is very stubborn and will not get close to someone very easy because she discovered how easy it is to have it all go away. Meiko says that Hisao just needs to be patient with Emi and that Hisao has gotten closer to Emi than anyone before. Hisao states that he feels that he and Emi have not gotten any closer, just after he says that Emi shows up looking hurt. She states that that will make what come next easy, Meiko tries to intervene but Emi cuts her off and tells Hisao to leave, Meiko tries to convince Hisao to stay and close to the end Emi regrets her words and pleads Hisao to stay too. However Hisao declines, saying it will be better if he leaves instead, exiting the house. Hisao returns back to Yamaku, thinking over what he has just done.
Hisao returns to his room, but had difficulty sleeping for tomorrow. Thinking of how he should apologize to Emi, he is reminded of the letter from Iwanako. Searching his room, he manages to find the letter and starts reading. After reading the main points of the letter, he discovers that Iwanako noticed back then that Hisao seems to have given up on happiness, which sounded familiar to him. Iwanako regretted not supporting him, believing that he wouldn't have acted so alone back then. She wonders if they will ever meet but thinks that they shouldn't and ends the letter by wishing him the best. Hisao places the letter on his desk, feeling comforted by it. He wonders what would've happened if he acted differently, however he concluded in that there was no point wondering now but he shouldn't forget either.
==Act 4 ~ Motion==
[[File:3Motion.png|thumb|left|Act 4: Motion]]Alternative Path continued
Waking up the day after being kicked out of Emi's house, Hisao continues to think whether he made the right decision or not before hurrying down the track. However it appears that Emi has yet to arrive. After a bit of waiting, Hisao begins to start his morning run, hoping to see Emi arriving soon. But Emi still didn't come, Hisao begins to worry, heading to the Nurse and hoping he knows where she is, or at least how to deal with this situation.
Unfortunately the Nurse has no knowledge of Emi's whereabouts but is aware of how unsuccessful last night was. After being filled in on what happened, the Nurse is surprised on how far Hisao actually went but now doubts he will go further. This motivates Hisao in thinking that he won't give up, claiming that he loves her. This interests the Nurse and he even wishes him luck.
The morning passes and lunchtime arrives. Hisao has decided how he is going to do things as he heads towards the roof, expecting only Rin. Instead he finds out that Emi came to the roof before him, foiling his plans. Emi apologizes for sleeping in and missing the morning run and the two begin to awkwardly converse. Hisao attempts to invite Emi somewhere after school but fails as she says she promised to help the [[Track team|track club]] after school. With that, Hisao begins to have indecisive thoughts as he never gets the right opportunity to confront her. Days keep on passing and Hisao feels worse as he sees a tired and distracted Emi.
One lunchtime Hisao finds Rin alone on the roof. Being the first time that Emi isn't here, he begins to worry about her condition even more. Asking Rin where Emi is, she answers back with a confusing answer. They continue to have this awkward conversation until Emi finally arrives, with her usual energy. Before anyone could speak, Rin announces that that she is going somewhere less awkward. This surprises both Emi and Hisao due to Rin's sudden straightforwardness. As Rin leaves the roof, Hisao explains to Emi that he was worried but Emi replies by saying that it isn't unusual. This annoys Hisao, bringing him to mention how he's worried ever since that night. Emi shows her discomfort of the subject but states that he had a week to bring it up. He apologizes about that but quickly starts speculating if he's been the cause of Emi's distractions lately. Emi denies it but Hisao admits that he hasn't helped her either, this makes Emi think that they should stop being together. Hisao sees her reluctance in saying that and starts saying that he will help her no matter what. Emi wants him to stop helping her but Hisao wouldn't let up, he continues to press on, nearly making Emi break down. She asks why he is so determined to help, and he replies by confessing his love towards her. This finally makes Emi break down, hugging Hisao as she bursts to tears answering back his feelings. After a while, Hisao manages to calm her down. Emi then invites him back to her house again tomorrow, Hisao accepting her offer. The lunch bell rings and Emi leaves the roof with a kiss. Hisao also leaves the roof, feeling better than he ever has before. The scene ends and continues on with the beginning of the normal route of Act 4 the next day.
After the events that went on the week before, Hisao wakes up to meet Emi at the track for their morning run. Emi is at the track waiting for Hisao. She is very impatient and wanting to get started. She tells Hisao that they are going to see her Dad today. Shocked, Hisao is supportive and agrees. They head to the nurse and get checked out and head for the bus station. When they get to the bus station Emi tries to open up to Hisao, but can't get the words out. Hisao does not push her and agrees to wait as long as she needs. Once they get off the bus Hisao follows Emi to her mom's house. They enter and are welcomed by a hearty meal prepared by Meiko. They eat their fill and Emi's mom then gets them ready to head out. Meiko drives Hisao and Emi to the cemetery. Once they are in front of the cemetery Emi seems to tense up. Hisao takes her hand and squeezes it, reassuring her and she relaxes. Meiko does not accompany them when walking into the graveyard. Thoughts race through Hisao's mind while walking with Emi, she has a fast pace, wanting to get where there are going in a timely fashion. Emi announces they have arrived and they stand on opposite sides of a tombstone engraved with a name and no other markings. Emi doesn't say anything for a brief moment, until saying that her favorite color is not pink, she continues about how most people think that her favorite color is pink. She tells Hisao that her favorite color is blue and that only her mother and father had known that. Emi then completely opens up to Hisao, saying that eight years ago today, she lost her legs and her father, in which Hisao tries to say that he is sorry, but she does not want to hear that, as everyone has said that to her. Emi says she is tired of hearing it, it is not like those people could have changed what happened to her or her father. Hisao goes to embrace her, she stops him, and continues what she is saying how when the accident happened the doctors thought that she was going to be paralyzed. When the doctors pulled her out she had already lost her legs. When Emi got to the hospital, she couldn't feel her legs because of shock, and only had temporary paralysis. It took her two months to visit the grave, she wasn't even able to attend the memorial service. Emi then tells Hisao that he was not her first boyfriend, and she ended up breaking up with that boyfriend because she didn't want to get to close to him. Emi then realizes that living life to the fullest doesn't just have to be by herself. She thanks Hisao for going with her and is very happy she met him. The two head back to Yamaku and Hisao is about to take his leave, until Emi invites him up to her dorm. The two head up the stairs and go into her room. Hisao and Emi both know what is going to happen.
Hisao and Emi just had intimacy between each other and then they fall asleep. The next morning Hisao wakes up in Emi's bed with Emi curled up next to him. Hisao makes a remark about how small the bed is, which he does not mind at all. Emi then wakes up and is so happy that Hisao is still there next to her. She explains how that was the best she had slept ever, no nightmares or anything. She then asks about what they are going to do today. Keeping their relationship to go on, and start molding their life together.
== Trivia ==
* Emi's route is tied with [[Lilly's route]] for most H-scenes (at three each).
Emi is running in the halls and crashes into Hisao Nakai. At first, Hisao is scared for his heart, remembering his cardiologist's warning to "not get hit in the chest". She apologizes profusely and then runs off again. Later, the Nurse confronts Hisao about his lack of exercise. Hisao asks him how he knows and he confesses to using "a spy" (who is later revealed to be Emi) to keep tabs on him.
Early in the morning, Hisao goes to the track to jog and finds Emi. If Hisao agrees to go running, he meets Emi at the track again and goes for a jog. She provokes him into a race, but he gets a heart murmur and collapses. Emi helps him to the nurse, where she gets a talking-to. Emi invites him to lunch to make up for it. Hisao joins Emi and Rin on the roof. Emi talks non-stop while Rin says little in her quasi-stoic way.
On the day before the festival, Emi grabs Hisao and uses him for help getting art supplies for Rin, who is still working on the mural. She runs out of Prussian Blue paint and either Emi goes alone to fetch some, or she takes Hisao with her. If the latter, Emi gets Hisao to agree to a physical training regimen with her.
Hisao and Emi continue their morning runs, growing closer each day. As the days go on, he notices she seems like a different person when she runs. At lunch she shows her goofiness, but on the track she shows her stubborn persistence. This comes to a head at her track meet. He sits between Rin and Emi's mother, Meiko, and sees Emi at her "Emiest" (as Rin says). As he's struck by how beautiful she is, he realizes he is falling in love with her. The next day, on a rest from training, Emi takes Rin and Hisao on a picnic. Though Rin and Hisao try to warn her, it rains. They escape into the Shanghai where they have tea and cake instead.
The next day, Emi does not show up for the morning run, Hisao tries to find out, while people like Lilly and Misha tease him about how much time they've been spending together. The nurse tells him she caught a cold from the rain. Hisao drops by her room after class. For the first time he sees her without her prosthetic legs.
In typical Emi fashion, they tease each other until the flirtations evolve into a pillow fight, where Hisao ends up on top of her. A moment of paralysis occurs where Hisao can't figure out whether Emi wants him to go further. They stop. After a little more conversation, she falls asleep in Hisao's arms. Hisao is quite content, until Emi begins to have a nightmare. When she cries out "Dad!" Hisao wakes her up, but Emi says she does not remember her dream.
Emi seems fine the next morning. Hisao contemplates confessing his feelings, but feels stymied by Emi's track captain, who often talks to her. The nurse laughs, and assures Hisao that nether is interested in each other romantically. Alone at lunch on the roof (since Emi gave Rin her cold), Emi admits that she has nightmares quite often. In typical Emi fashion, she prompts Hisao to kiss her, admitting she has a bit of a crush. They do. When he returns to class, Misha teases him about it, but for the first time, Hisao's heart feels light.
Hisao takes Emi on their first date -- a picnic in the park. On their way back, Emi stumbles, the same way as she did in the track meet. In the morning, she again collapses during her run, but refuses to tell Hisao what's wrong even as he presses her. Hisao tries to offer support, since clearly something is bothering her both mentally and physically. But she pushes him away.
One day, while Hisao is at the library, Emi calls him via the reference desk phone, asking him to come immediately. Hisao rushes to her dorm where Emi is in a wheelchair. Her leg has gotten an infection from overuse, which caused the stumbling and pain. She is frustrated at not being able to run, but resolved, as this is not her first time in a wheelchair. When Hisao comes to visit, their flirtations turn into wrestling. And for the first time, they consummate their relationship.
The next morning, though Emi can't run, she shows up at the track. They both steal away into a storage shed and get the idea to try anal sex. The experiment is... less than successful, and both end up feeling awkward and sore. Hisao returns to his room and sleeps until lunch. Emi comes by to see him and tells him they need to stop seeing each other so often, given that she needs to concentrate on exams. Hisao agrees, since he can still see her at the track and at lunch.
But Emi's condition is getting worse, not better. She says nothing to Hisao on the track and spaces out during lunch. After exams are over, Hisao confronts her about why she won't talk to him about it. Emi admits that, because the accident ripped everything away from her, she would never let that happen again.. Hisao leaves, feeling heartbroken that Emi will never let him get close to her. If Hisao asks Mutou and the nurse, Emi surprisingly invites him to dinner at her mother's house. Though nervous, they make amiable conversation until Mrs. Ibarazaki brings up the subject of Emi's father. Emi retreats to the bathroom.
If Hisao pursued her, Emi gets even angrier at Hisao and demands that he leave. Later at school, Misha tries to offer advice. If Hisao allows it, she tells him he needs to apologize to her. He does so in a tearful reunion on the track. (Otherwise, Emi tells Hisao that it's over and the game ends.) Appealing to her determinedness, citing examples of how she made sure he was at the track and created a dietary plan, Emi gives in. She tells him she needs time to think... but to show up for their morning run tomorrow.
If Hisao talked to Emi's mother, Meiko talks about how Emi tries to believe that the accident "wasn't a big deal", but -- keeping to Emi's promise -- tells him no details. Emi overhears and demands Hisao leave while she accuses her mother of breaking her promise. Meiko denies it, but Hisao acquiesces to go. Emi immediately regrets kicking him out, but Hisao knows if he stayed, it would only cause more pain. He returns to his dorm where he reads over a letter from Iwanako, the girl from his school before his heart attack, and wonders if he's giving up on happiness.
Hisao manages to apologize to Emi, saying that he won't stop trying to help her, not even if they break up (which Emi half-heartedly attempts to do) because he cares about her too much. Emi begins to cry and asks why he's trying so hard to help. Hisao says "because I love you." That seems to get through to Emi, as she finally breaks down in Hisao's arms. She asks him to come back to her house tomorrow, so she has time to "do this properly" and think about what she needs to say.
The next day, Hisao and Emi take the bus to her mother's, but all she'll say is they are going to meet her Dad today. They eat lunch and then drive somewhere. They stop at a graveyard where Meiko stays behind and Emi leads him further in. Hisao contemplates his mortality among these gravestones until they stop at one in particular. Emi starts confessing things about herself -- that she doesn't like pink, that she's not as popular as everyone thinks -- and that the accident that took her legs also killed her dad. And as a result, she resolved to stop worrying about the future, because there's nothing you can do about it. Until she met Hisao, who she couldn't keep at a distance anymore. Now she realizes if she is going to live in the moment, she doesn't have to do it alone.
When they return to the dorm, before they separate, Emi grabs Hisao. She asks him not to leave. Hisao doesn't care what context she's talking about, he says "of course". The two make love and fall asleep together. In the morning, Hisao thinks about how close they are now. That no matter what happens, as long as Emi's around, he'll be okay.
