The school informed their parents about the fact that they are dating. Sachiko is avoiding Tarou in the school because of all the teasing. Furthermore, she keeps getting along with Yuu. This irritates Tarou and makes him feel uneasy. So, Tarou wants to have sex with Sachiko and asks Kenji for advice. Kenji says that when her desires overcome her fears, Sachiko will want to do it. So Kenji suggests an operation to wake up the pervert in Sachiko by showing her ero stuff. Tarou doesn’t want to send a naked photo of himself to Sachiko nor does he want her to see other naked men, thus ero-magazines are out of the question. And so, they decide to use hentai manga. They plan to put the ero-manga in Sachiko’s desk in a way that when she sees it she’s alone. They fear that otherwise she’ll just ask whose it is, complain and throw it away. Tarou and Kenji go through a lot of trouble to make the plan succeed. And it unbelievably did. She skimmed through it and she couldn’t find a chance to get rid of the ero-manga and so she took it all the way home with her. The boys are sure she’ll read it at home. Kenji says that now that they woke the pervert inside Sachiko, it’s just a matter of time before she’ll ask Tarou to have sex with her. Will Sachiko really become a pervert?
