Yui, a serious beauty teacher who is also popular with students, is an excellent teacher who can serve as a grade chief at a young age. However, I had a terrible problem child in my class, and I was worried because I couldn't hear what I said no matter how careful I was. One day, the problem child "Tatsuo" stops coming to school. Yui was worried and when she called, she said, "I want to talk, so I want you to come to the designated place." A noble, beautiful, gentle and justice female teacher is laid down while trying to save a bad student, and also receives sexual intercourse from her friends. Thoroughly depict the masochism that blooms as a result.
