A middle school student who has a huge love for literature and a crush on Saeki. It is because of his infatuation of Saeki that he steals her gym uniform. Sawa Nakamura, an isolated loner in Kasuga's class witnesses him stealing the uniform. She then blackmails him into forming a contract, tying them together as "friends."

~! Initially against his contract with Nakamura, he cautiously followed her requests and disliked their meetings. However, over time he begins to see that Nakamura is actually lonely, and longs to escape from the people of the town, much like himself. Kasuga later develops strong feelings for Nakamura, promising to one day take her to the "other side." !~

~! Some time after the kerosene incident, he starts a new life, trying to keep his mind and heart calm. He states he doesn't have a death wish. Nonetheless, his feelings confuse him, and an old friend turns him to face his past. His hope now lies in friendship, with Tokiwa Aya-san. !~ 

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.
 
As the saga unfolds, we see Takao struggling to decide whether to confess or cover up his misdeeds at the same time that he tries to win over the girl of his dreams, and avoid the blackmail attempts of Nakamura, his new ”BFF.”
 
Smart, funny, and emotionally engaging, The Flowers of Evil introduces a character who's not a hero, but just an ordinary teenager in search of true love and real friendship.

Kasuga Takao is a boy who loves reading books, particularly Baudelaire's Les Fleurs du Mal. A girl at his school, Saeki Nanako, is his muse and his Venus, and he admires her from a distance. One day, he forgets his copy of Les Fleurs du Mal in the classroom and runs back alone to pick it up. In the classroom, he finds not only his book, but Saeki's gym uniform. On a mad impulse, he steals it. 
Now everyone knows "some pervert" stole Saeki's uniform, and Kasuga is dying with shame and guilt. Furthermore, the weird, creepy, and friendless girl of the class, Nakamura, saw him take the uniform.

Will it be possible for Kasuga to get closer to Saeki, despite Nakamura's meddling and his dark secret? What exactly does Nakamura intend to do with him?
