One night, while drinking, Yokota found himself at his department chief's house. He instantly fell for the chief's wife, Seira, the moment he saw her. Suddenly, an opportunity arose for them to be alone together. Things quickly escalated, and before long, the two were spending time alone. Having suffered through days of longing, Yokota could no longer restrain himself and forcibly pinned Seira down. Though she initially protested, saying "No, we can't," she gradually grew intrigued, and their relationship deepened further and further.
