Akane Misaki has decided to start living alone. She feels a sense of discomfort due to the abundance of her belongings in her small room, but she thinks it is because of the small space and starts to unpack her clothes. After a while, the door opens, and an unfamiliar man appears. The man's name is Ken Hazama; according to the landlord, due to a contract mistake, they ended up in the same room.
