A wife, Mao, and her husband, Toru, who is 20 years older than her. Toru dotes on Mao. But he dotes on her so much that he ends up controlling her. At first, Mao only signs the contract that Toru had drawn up, but he starts calling her every 30 minutes, forbidding her from going out, and eventually he even installs security cameras in the house. Then, the drain in the kitchen breaks and they have to call a professional.
