Forced by Nakamura into Saeki’s gym cloths, Kasuga finds himself blackmailed into spending even more time with his tormentor. Strangely though, when Nakamura is accused of stealing money Kasuga finds himself standing up for her.

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.
