7th year of marriage. Busy days working as a salesman at a life insurance company while being busy with housework and childcare. She has noticed that these days she is seen less and less as a woman, both at home and at work. Somehow she was lonely, and about half a year ago, at the beginning of the month when her work was over, she lied to the company that she was outside and met someone she met on a dating app and had a relationship. Yumika, who was originally working, was strangely excited by the thrill of the early afternoon on weekdays and the guilt of betraying her family, and since then she has been stuck in the swamp of adultery. Today is the long-awaited beginning of the month, and she is having a special moment when she sneaks out of her company.
