The chapter opens with a conversation between a first-year student named Yukari and his roommate, a cute girl named Mami. Yukari tells his roommate that he's feeling a bit "hot and bothered" by his roommate's behavior. He tells Yukari that he came to visit Mami because he is the brother of the girl's current boyfriend, a fellow student named Makina. He asks Yukari to stay by his side for a bit so that Yukari can "squeeze" some time with his friend. The two exchange pleasantries and Yukari says that he is learning how to cook so that he can "experiment" with kun, his current boyfriend. When Yukari asks why he is going out with Mami, he says that she doesn't approve of him. He says that if she used his last name, it would be "odd" and that he would just not be able to imagine marrying her. He explains that he was trying to "shake him up" by making her drink some drinks and eating some sandwiches. He also says that Mami has been making him some fertilizer for roses so that she can "surprise" her boyfriend. He adds that he has written a "dating schedule" to help him prepare for marriage.
