Arisa is a wife who is living a happy life with her husband Noboru on her first anniversary of marriage. One day, a man in a shabby suit moved next door. For a moment, Arisa couldn't believe her eyes. The man is Kaifu, the former boss of the company Arisa worked for before she got married. When I heard the story, I was fired from the company, and it seems that my family had abandoned me. Kaifu resented Arisa's happiness. "You look innocent and settle into the position of a housewife..." From this day on, persistent harassment began.
