From Katawa Shoujo Wiki
Even if some endings are not complete (not having an epilogue, like you said)... they still fulfill me... hanako's for example. They don't exatcly know what awaits then in the future. Its then time to use your imagination and create an epilogue for yourself, knowing that they will know each other better because the wall that separeted then was broken, they love each other, and can probably enter their future together xD (this is my view of things haha)
