A couple named Kuromi runs a ryokan in a certain hot spring town in the Kanto region.
The wife, Nami, married her former boss, Kentaro, during her OL days.
Afterward, Kentaro took over his family's ryokan, and now they run it together.
However, due to the economic downturn, their customer base has decreased, putting them in a dire financial situation.
Additionally, an employee named Saiji, who had been working at the ryokan since before their time, caused problems with his poor attitude,
causing the couple much trouble.
One day, Takimoto, a loan shark from whom Saiji had borrowed money, came to demand repayment.
In a panic, Saiji came up with the worst possible idea: offering Nami's body, who is a young woman with large breasts.
