5화: Keita가 실수로 Miharu를 만지작거리자 의심이 생기고, 도서관 추격전과 창고 갇힘 사건이 벌어진다.

5

While talking to his friends, Keita accidentally gropes his fellow student, Miharu Mikuni, and gets slapped. Ako and Riko become suspicious that Keita has been 'cheating'. When Keita goes to study at the library, Miharu, who is a student librarian, becomes too intimidated by Keita to go to the bathroom, believing that he will attack her if she takes her eyes off him. Keita chases after her as she tries to get to a washroom, intending to return a book she dropped (which looks like Miharu's student identification booklet) and ends up dragging her into various hiding spots to hide from Ako and Riko. Unfortunately they end up getting locked in the gym storage room and their hashed escape plan leads to Miharu relieving herself on Keita's back. They eventually manage to escape from the room and Keita promises to keep the incident secret, though he gets beaten up when he accidentally sees that Miharu has removed her panties.
