After wandering around and going to college, I decided to start living alone. When I finished organizing everything, my mother told me that it was important to get along with my neighbors, and I was forcibly taken to the next house. When I opened the door, greeted a woman living next door and raised her face, that person was Mr. Morisawa, a tutor when I was a student. The teacher I met again after a long time was bewitchingly beautiful and I was excited. And on the night of the move, I heard the cry of the couple's activities from the other side of the thin wall.
