Akane Misaki has decided to start living alone. She feels uncomfortable with the amount of luggage in her room, but thinks it is because the room is small, so she begins to change her clothes. After a while, the door opened to reveal a strange man. The man's name is Ken Hasama and according to the landlord, they ended up in the same room together due to a contractual error. The vacant room will be available in a week, until then Akane and Hasama will stay in the same room together. The first day went by without any major problems, although the situation was not favorable for Akane. The two sleep together on the same futon. Akane has difficulty sleeping under unusual circumstances. Even the inexperienced Akane could tell that they were having sex when she heard the glamorous voice coming into her ear from the next room. As she listened to the voices, Akane's hand reached for her own crotch, even though Hasama was sleeping next to her.
