A week of cohabitation between Misaki Akane and Hasama Ken, which had begun with a mistake in their contract, had passed. One day, Hasama was worried that Akane had not come back home yet. Since she was not answering his phone calls, Hasama decides to go and pick her up from her part-time job. While Akane was happy that he came to pick her up, she also had mixed feelings about their cohabitation ending in a few days. Due to the alcohol he had drunk while waiting, Hasama fell asleep on the table as soon as he got back to their apartment. Akane, who was worried, tried to wake him up. Hasama felt the softness of Akane's breasts on his back, and overwhelmed with lust, pushed her down. Akane pleaded with him to let her take a bath first since she had just come home, and Hasama came to his senses and decided to take a bath together. Akane, who did not want to be forced into doing anything sexual in Hasama's usual way, took a certain action.
