Since elementary school, the calm and timid Takuya Nonosaki has bottled up feelings for his boisterous friend, Kazu Kuwabara. Although he may fool around and act rash most of the time, Kuwabara wears an honest smile—which is something that Nonosaki cherishes. The thought of confessing never comes to Nonosaki's mind, and he believes that he has no reason to do so.

One day, the pair and two female classmates happen to cause chaos inside their room. While at it, a broken fluorescent bulb electrocutes them, resulting in an unimaginable scenario—the boys and girls have switched bodies! With each of them fulfilling their own curiosities, Nonosaki's dreams might finally see the light of day.
