After having been dumped by his girlfriend Hazuki after he lied about his college acceptance in order to have sex with her, Suguru encounters a beautiful girl in the middle of the river, and ends up helping her find her broach. The next day, while looking for his uncle's boarding house, he finds out that the main floor of the boarding house encompasses a strip club, and that the girl he helped before, Urara, also lives in the building. Soon enough, they end up living in the same room, as roommates. Suguru's goal is to take a year off to study so that he can eventually get into Hazuki's college, but with so many beautiful women around him, how can he possibly concentrate?
