Brother, this is the story of 24 year old Rinko, who is an office worker but is a staunch "otaku" (an anime and manga enthusiast) at heart. The poor girl used to live alone comfortably, but one day suddenly her luck changed! Strange "doors" appeared on both the walls of her room which connected them to the rooms of her neighbors. Now the situation is such that they have got "roommates" without permission. In the room on the left, there is a very smooth and cute boy who is always kind to Rinko. But brother, the guy on the right is a complete "fierce" fighter, always in a hot temper. The twist comes when Rinko realizes she already knows one of them! The poor girl's privacy is ruined, and now every day brings new threats and "heart-pounding" blows for her. Let's see how this girl manages to survive between these two amazing guys!
