Kanou is a failed writer who has just been evicted from his apartment. As he's trying to figure out how to put a simple roof over his head, he bumps into his friend from high school, Satomi Tatsuo - who offers him a place to live on two conditions. The first is that he can only stay for one month, and the second is that he must obey everything Satomi tells him.
