1LDK + JK Ikinari Doukyo? Micchaku!? Hatsu Ecchi!!?

Akane Misaki has started living alone. She feels uncomfortable because there’s a lot of luggage in her room, but she thinks it’s because the room is small and begins to change her clothes. After a while, the door opens, and an unknown man appears. The man’s name is Ken Hasama, and according to the landlord, they ended up sharing the room due to a contractual error.
