Eita Kidō enters high school with the aim to attend medical school. Due to his parents getting divorced and his intention to maintain his grades, he shuns anything to do with romance or love. One day, the school beauty Masuzu Natsukawa invites him to walk home with her, though he initially refuses. After she continues to do this for several days, he gives in and walks home with her. Masuzu is tired of constantly getting confessed to by boys, so she suggests that she and Eita become a fake couple. Although Eita tries to refuse, Masuzu blackmails him into becoming her boyfriend in name only. News spreads fast within the school of the new couple and Eita's childhood friend Chiwa Harusaki begins to confront Masuzu for Eita's affections.
