One month later it is summer. The three have been ignoring each other. On Kinoshita's initiative, Saeki and Kasuga talk, only to break up. Kasuga is a shell of his former self. His mother is upset. He pukes. He knows Saeki is going to be alright without him, but even in his dreams, he can't stop thinking about Nakamura.

Kasuga enters Nakamura's room. He finds her diary and starts reading it. He recalls what had happened. Nakamura comes back, seizes the diary and runs away. He follows her and catches up to her. This time, he asks her to make a contract with him: they'll do what they can in order to leave for good someday.
