During an art class, Futaba, who has an obsession with breasts, end up drawing various pictures of breasts, one of which the principal determines is a work of art. While at the triplets' house, Shinya tries to stop Yuudai from playing around with Mitsuba's panties, only to get labeled as a pervert himself. This leads Futaba to believe Shinya has an interest in Mitsuba's panties, and continuously tries to give him large amounts of panties all day. When he tries to stop Futaba, Shinya ends up in another seemingly perverted situation in front of Mitsuba. (Source: Wikipedia)
