Jun, the mother, wanted to find a way to get her reclusive son, Yuzuru, to go outside. One day, she accidentally witnessed Yuzuru masturbating and thought that if he experienced pleasure from others, he might desire companionship and venture out. Driven by this idea, Jun began to stroke her son's penis to satisfy his sexual needs. However, her plan backfired; instead of encouraging him to go outside, Yuzuru pressured his mother for sex.
