Miyuki (Saeka Hinata) lives a peaceful life with her husband. One day, she goes upstairs to bring coffee to a repairman fixing their electric heater, only to find him holding her underwear... A few days later, while her husband is away on a business trip, the repairman—who has since been fired from his company—shows up at her door. "It's all your fault! I got fired, you know, ma'am. Now, you're gonna take responsibility for this."
