The beginning of the film was the scene where Momo Honda was going out of the corridor after school when she discovered that there was still a student staying, seeing that she was difficult to study, so she stayed to help him. The student fell in love with his teacher the next day he gave her a gift to express, but responding to that emotional thing was the engagement ring, obeying the beautiful teacher. The student's desire to his teacher is to fuck her once, and in 1 minute of weakness the teacher agreed.
