Rin admits she wasn't ready for the gallery and walks back to school. Nomiya is outraged when he learns what Rin has done. Emi suggests she and Hisao find her and "kick her ass", but Hisao persuades her against that. The two return to the dorms to prepare for exams.
Nomiya interrupts Mutou's final exam to talk to Hisao. He has been unable to find Rin since she left. When prodded on why he pushed Rin into it, Nomiya explains that he saw it as his duty to ensure her talents didn't go to waste. Hisao leaves Nomiya and finds Rin in the unused classroom where they first met. Rin continues to hold herself at a distance. Hisao explains that Sae and Nomiya believe Rin is throwing away everything she has been working towards. He convinces her that she needs to apologize to Nomiya.
Hisao waits outside as the art teacher scolds Rin, lecturing her throwing away a promising career. She states, in her detached way, that the exhibition was a mistake. Nomiya frustratedly tells her she might not be an artist after all and storms out. When Hisao goes in to comfort her she pushes him away. Hisao tells her that Nomiya was trying to make her into someone she wasn't ready to be, and that in a way he was doing the same thing by trying to make them "more than friends". She cries in his arms, and Hisao holds her until she's done, realizing he fell in love with her a long time ago, even if he isn't able to connect with her well.
Rin explains it's easier to express herself with art than with words. She's trying to get people to understand her so she doesn't feel so alone. Hisao realizes she's been reaching out to him like he's been reaching out to her. She accepts that it's okay to never be completely understood, but dares to trust in Hisao a little more.
On the first day of summer vacation, a heavy rain pours outside. Hisao hears a thud at his door. Rin stands in the hallway, soaking wet. She's gone for a walk in the rain and, since Emi has gone home for the summer, she needs help changing into dry clothes. Hisao nervously agrees to help. As he dries and undresses her, one thing leads to another. Making love is a transformative act for both of them: Rin discovers what it feels like to not be alone and Hisao learns to stop worrying about the future.
Afterwards, Rin takes him back to the hill of dandelion flowers which are now in full bloom. She asks Hisao if he loves her. He isn't sure. Rin tells Hisao "I love you" anyway, describing the phrase as "a weird taste". She admits that she's a little bit afraid of Hisao, because he makes her feel like she should be someone else. She starts to cry.
But the things about her that frustrate him are also what he admires most about her. Rin decides it's okay not to change. Hisao asks Rin if she still plans to become an artist, but Rin asks him to watch the sky with her instead. She asks him "What's the right word for when it feels inside your heart that everything in the world is alright?"
