Bookworm Takao and class bully Sawa may not appear to be the best couple, but together, by chance, they shake up their entire rural community to its core. In love with the class idol, Takao is given a chance to become a real hero and finally break out of his shell after righting a wrong he committed in a random moment of passion and affection. With the help, or blackmailing by, Sawa Nakamura, Takao is on his way to change his future and enter a world of decadence.
Contrary to Takao's predictions, the girl he was falling for, Nanako Saeki, responds by eventually accepting the bibliophile for who he is. Or at least, who she thinks he is. In the second volume of Flowers of Evil, Takao's lies have given him new life with his now new girlfriend Nanako. And as he becomes closer to Nanako, his relationship with Sawa only deepens as the ""contract"" they share weighs heavily on the teen.
