Five years into her marriage, housewife Kaori lives a peaceful daily life. Though she has no complaints about her life with her husband, she recently began sensing something off in his behavior. He had secretly been laid off from his company but was desperately trying to handle it on his own. However, his body had weakened, leaving him unable to perform sexually. As Kaori gradually noticed her husband's condition, she grew anxious about the changes in his heart. One day, she realized he wasn't going to work but instead went to a park, where a suspicious-looking man approached him. Her husband begged the man to have sex with Kaori, and right there, she was forced to watch as another man took her body. The deep-seated desire hidden within her husband's heart had finally surfaced through his actions.
