Popular and serious beautiful teacher 'Yui' is so outstanding that she was appointed as the grade leader at a young age. However, she has a troublesome student in her class who never listens to her warnings, causing her much distress. One day, that problematic student 'Tatsuo' stops coming to school. Yui calls him out of concern and is told, 'I want to talk, so come to the specified location...'. A noble, beautiful, kind, and justice-loving female teacher tries to save a delinquent student but ends up being subdued and even subjected to sexual acts by his friends. This thoroughly depicts her blossoming masochism.
