A couple named Hoshino runs an inn in a certain hot spring town. However, due to the economic downturn, the number of guests has decreased, and their management situation is dire. Additionally, a man named Saji, who has been working at the inn since before the previous owner's time, has poor work attitudes, causing trouble for the couple. One day, Saji's loan shark, Ishigami, comes to demand repayment. Panicked, Saji comes up with the worst idea: offering the body of Natsuki, a young woman with large breasts.
