This work is a story based on actual experiences. Rather than mere bullying, it portrays a mother who deeply loves her daughter, yet imposes strict control over her under the guise of discipline. As a result, the daughter gradually suppresses her true self and begins walking a dangerous path. The narrative explores the twisted affection, obsession, and masochistic tendencies that emerge throughout this process. On the surface framed as education, the story reveals profound psychological conflict and the breakdown of human relationships.
