Daiki, who had been secretly sending lascivious glances to his neighbor's wife, Momoko, decided to call an escort service, accepting the imperfection of reality. The one who arrived was Momoko, who had started working in the sex industry without her husband's knowledge to repay her parents' debt. Although both were surprised, Daiki, who had originally lusted after her, saw this as an opportunity to form a relationship. Daiki continued to visit her as a customer, and Momoko continued to accept him, continuing to engage in physical intimacy. As she served him, she gradually became aware of her own growing sexual desire and realized that she could not go back.
