For downsizing, Koutaro and Hideki were told that one of them had to be fired. Considering Hideki, who has a family and just bought a house, the single Koutaro chose to retire voluntarily. 'Someday I'll repay them...' Hideki and Rinko swore in their hearts. Half a year later, Koutaro, who had returned home and taken a job as a tour bus driver, went to Tokyo for work. Rinko, who came to greet him, aroused Koutaro's desire. He took advantage of Hideki's absence to force himself on Rinko. Someone he had once been indebted to. Rinko couldn't strongly refuse and ended up having a relationship with him.
