It's an affair with the wife of a neighbor who invites me to go out for lunch without her husband. Sakurai-toge Pass

Living alone in college, I was tired of studying and working part-time. It's noisy outside to finish the task that day. Apparently someone is moving into the next room. After a while, the chime rang and the wife of the neighbors came to greet him. When I looked up my face, I saw Mr. Sakurai who was a tutor when I was a student. The teacher, who had reunited after a long time, was unprotected by the fair. Furthermore, from behind the thin wall I could hear the work of the couple, and I became aware of the teacher as a woman.
