Usui, who has been married for four years, is currently teaching at an English conversation school. It is said that the couple worked together and enjoyed the occasional holiday together. However, since about half a year ago, each other has been busy, and the couple have started to spend their holidays separately. At that time, a student at the school confessed that he had a physical relationship if he was too lonely. And she crossed the line and was fascinated by the world of immorality, and she couldn't stop it anymore.
