Tetsuo is a senior in college working part-time at the local supermarket. One day, he meets an attractive customer Satoru, and they start dating after he takes care of her after collapsed from anemia at his workplace.
Tetsuo is mysteriously drawn not only to Satoru but her mother, a stern but attractive teacher, and her younger sister, Mitsuru, a bright girl in contrast to her withdrawn elder sister.
One evening, Mitsuru invites Tetsuo to a local pub, to warn him against becoming further involved with Satoru, as she is overly dependent on their mother and frequently uses her anemia to seduce men.
