Flowers Of Evil Vol. 3

Takao Kasuga is an introverted middle school student and bookworm whose favorite book is Baudelaire's Les Fleurs du Mal. He is infatuated with a girl in his class named Nanako Saeki whom he idolizes from afar as his muse. One day after school, he returns to his classroom alone after forgetting his book there and finds Nanako’s gym clothes, which he impulsively steals. Word begins spreading around school that a pervert stole Nanko’s clothes, and Takao is wracked with guilt and shame. Worse than that, though, is the fact that fellow classmate Sawa Nakamura, a cold, contemptuous girl whom everyone in class ignores, saw him in the act. In order to keep his secret hidden, he enters into a “contract” with her in which he must do anything she says, no matter how unreasonable.
In Vol. 3, Takao and Sawa sneak into school at night and turn their classroom into a “sea of shit-bugs.” The next day, Takao attends school expecting to be exposed as the culprit, but a series of happy coincidences lead to the matter being viewed as the work of a pervert and cleared up. However, Takao is unable to bear the pressure of his guilt, and what’s worse, Nanako ends up finding out about it!
