Aya had built a good family relationship with her daughter's boyfriend. However, the boyfriend seemed to have a strong sex drive and frequently had sex in her daughter's room. The sounds could be heard in Aya and her husband's bedroom, and even her husband muttered, "He's amazing." One day, when Aya returned from shopping, her daughter wasn't home, and the boyfriend was masturbating alone. Flustered, Aya listened as he consulted her, saying, "I'm troubled by my strong sex drive. What should I do?" Aya soothed him, saying, "It's not strange for a young man to have a strong sex drive," but the boyfriend's sexual urges didn't stop. While desperately resisting, telling herself she shouldn't, Aya's legs began to shake, and she felt so much pleasure she couldn't stand.
