In the summer of my third year of university, my mother asked me to take a leave of absence because I was engrossed in studying, so I decided to stay at my uncle's house in the countryside for a week. In the countryside, my uncle, the owner of the house, and Rinko, who was gentle, greeted me, and I felt nostalgic for the two of them. A few days later, Rinko, who was supposed to live innocently, had a secret meeting with a man at the front door. There is Rinko who manages a man with an overwhelming slave relationship. When I was stunned by how different I looked 180 degrees from usual, I was invited to teach a secret that evening.

The nephew discovered his aunt secretly with a younger man and the outcome.
