Students express their deep-seated resentment toward their teacher through brutal revenge. The story follows the transformation of a serious, strict educator into a figure of complete subjugation under the hands of her pupils. Gradually, the girls dismantle the teacher's mind and body until she is utterly dominated. She is driven into a state of despair unlike anything she has ever experienced, confronting her absolute limits. The traditional teacher-student hierarchy is completely inverted, depicting her descent from an authority figure into a humiliated, broken servant. The intense shame, agony, and psychological collapse she endures throughout this process deliver a powerful, lasting impact.
