Rina and her husband visit a secondhand home viewing. Standing quietly in front of the house is Tsuchiya, the former resident. He once owned this house, but after his factory went bankrupt, it was seized and he lost everything. Forced to work on distant fishing vessels to repay his debts, he returned to find his family gone, leaving him as merely a silent observer of the home he once loved. When he sees Rina during the viewing, something deep inside him stirs, compelling him to step back into the house. Two months later, as Rina begins her new life in the house, Tsuchiya reappears. As past and present collide, their fates intertwine in a gripping tale of desire, guilt, and forbidden longing.
