Mr. and Mrs. Hoshino run an inn in a certain hot spring area. However, due to the recession, the number of customers decreased, and the business was in dire straits. Furthermore, Saji, a man who had been a servant at the inn since the previous generation, has a bad attitude towards his work, causing a lot of trouble for the couple.

In a panic, Saji makes the worst idea of offering the body of Natsuki, a busty beauty around his age.
