Married for three years... A lewd drama that attacked the cold Kobayashi couple. The trigger was a casual remark from Kaifu, a man who lives in the neighborhood. Pretending to be kind, Mei is given medicine, stripped of her clothes, and embarrassingly photographed. Kaifu's perverted play gradually escalates, contrary to Mei's anguish because she can't tell her husband about it. The bizarrely developed breasts are toyed with like toys.
