I was a college student who lived alone and was devoted to studying and working part-time. That day, when I was finishing my homework, it was noisy outside. It seems that someone has moved into the next room. After a while, the chime rang and the neighbor's married woman came to say hello. When I look up, I see Mr. Sakurai, who was my tutor when I was a student. The teacher who she met again after a long time was bewitching and defenseless. Furthermore, I could hear the workings of the couple from the other side of the thin wall, and I became aware of the teacher as a woman.
