The story opens as middle school student Takao Kasuga receives an F on a math test. But he doesn’t even seem to notice because he’s too engrossed in surreptitiously reading Beaudelaire’s The Flowers of Evil. And the day goes downhill from there. In a moment of weakness, he finds and takes home the gym clothes belonging to sweet, pretty Nanako Saeki on whom he has a major crush. Unfortunately for Takao, there’s a witness to the theft: Nakamura, who has a huge chip on her shoulder and a sadistic streak.
