Hinata married after continuing her secret relationship with her teacher, Yukio, while she was still a student. It was a happy life, but there was also an age difference, and I was somewhat dissatisfied with the gradually diminishing nightlife. When I greeted him in my underwear to make him feel that way, Yukio brought Iioka, her classmate, home. Later, Iioka, who was alone with Hinata, couldn't stand it and approached her. However, the reason why this netorare was secretly established is Yukio's job, who has a twisted desire to see his wife happy while being with someone else.
