Saeki Nanako is a smart, popular girl admired by many, but especially by a boy named Kasuga Takao. She accidently leaves her gym clothes on the floor and they are stolen by a mysterious "pervert". Despite this, she manages to keep on smiling and manages to date her lover Kasuga. However everything starts to go downhill because of Nakamura's constant interfering.
Saeki's biggest problem isn't Nakamura herself, though. Struggling with her own loneliness, lust and confusion, she does what she thinks is best.
