It’s been a while since I went to my wife’s parents’ house. So, when I saw Chihiro-chan (my wife’s sister) whose atmosphere changed, I was a little surprised. Chihiro, who had always thought she was a child, became an adult woman. I have become conscious as a woman. When my wife went out and was alone, I couldn’t control the lust that suddenly came up and I committed Chihiro-chan.
