Volume 1: Izumi returns from a business trip to find his apartment ransacked to the bone. Practically penniless, he moves into the only shelter he can afford: a room in a battered multi-family complex. As if the less-than-livable conditions weren't bad enough, he has to put up with his new weird, rude and tactless neighbors - and one of them is Haruto, the superintendent.

Volume 2: Everyone in the complex has seen Momo and Jin in a compromising situation at least once or twice. But what exactly is the relationship between these two men?
