The chapter opens with a discussion of premarital sex between two students at the university. The first student, Mami Tamura, has just had sex with a man named Souichi Kitou, a classmate from her second year. The second student, Mamoru Sasaki, is the chairman of the school's social committee. The two discuss the possibility of having sex before marriage, and the second student says that he has not had a boyfriend since he was a child. He asks the committee chairman why he is looking at him like that. The committee chairman says that it is his chance to have sex with someone, and that he would like to have a boy as a suitor. Mami says that she is not interested in the idea of sex, but that she would like a man to be interested in her. She asks him why he looks at her like that, and he replies that he is trying to get a "boy" to go for it. Mami asks him if he remembers his classmate from his second year, souichi, who she thinks is the same person as her current suitor, and she wonders if the man remembers her as well. She then asks him to tell her what should she do. He tells her that she should "rattle my startle" and knock someone "plain like me." He then asks her why she does not switch with him and work on her math homework. She tells him that she has to do this because she has never done such a thing before. She says that even though she looks like this, she is skilled at it, because she does all of the housework at her home. She thinks that the man is going to kill her
