A couple, the Tamuras, run an inn in a certain hot spring town in northern Kanto. The wife, Rena, married her former boss, Yuugo, during her OL days. After that, Yuugo took over his family's inn, and now they manage it together. However, due to the economic downturn, their management situation has become dire. Moreover, a man named Kawagoe, who had been working at the inn since before the previous owner, causes trouble for the couple. One day, Kita, a loan shark from whom Kawagoe had borrowed money, comes to demand repayment. Panicked, Kawagoe comes up with the worst possible idea: offering Rena's body, a big-busted beauty.
