"Monami" lives with her son before her husband. "Katsuji" is a tracer of the landlord who noticed the size of Monami's chest. Monami's part-time income was not enough to cover her living expenses, and she was delinquent in rent. Katsuji called it a collection of rent delinquency, but from the beginning he was fascinated by Monami's rich body and approached with a bad friend.
