A high school delinquent named Nagi harbors an intense hatred for his class president, Hayasaki, who is always scolding him for breaking school rules. This animosity takes a sharp and unexpected turn when Hayasaki catches Nagi in a compromising act in the school bathroom. Instead of punishing him, Hayasaki helps Nagi reach a climax. From that moment on, Nagi finds he cannot stop thinking about the class president. Hayasaki’s behavior changes completely, as he now looks at Nagi with gentle eyes, calls him handsome, and becomes easily aroused in his presence. Nagi soon discovers he is unable to achieve orgasm without Hayasaki’s assistance, leading him to question his own obsessive feelings.

The story is set in a contemporary Japanese high school and follows this bizarre and erotic dynamic. Nagi is characterized as a rebellious, short-tempered troublemaker, while Hayasaki appears to be a dutiful and responsible student on the surface, but harbors a much more perverted and submissive side. As their secret relationship develops, the two begin a journey of growing up together, navigating the strange sexual tension and emotional dependency that has formed between them.

The manga is a single, complete volume that focuses entirely on this central pairing. Its narrative arc traces the evolution of their relationship from hatred and antagonism to an obsessive and sexually charged bond, exploring themes of control, dependency, and coming of age within an explicit comedic framework.
