My daughter had a boyfriend and was aware of a good relationship with her family. However, my daughter's boyfriend seemed to have a strong sexual desire and had sexual intercourse many times in my daughter's room. It could be heard in Chisato's bedroom, and her husband even muttered that he was amazing. One day, Chisato came home from shopping and went to her daughter's room to eat with her if she liked, but her daughter was not there and he was masturbating alone. Chisato was a little flustered, but he asked me what I should do if I was in trouble because he had a strong sexual desire.
