For 18 years, a mother has continued to provide sexual care to her son, a student studying for university entrance exams, claiming it was "to help him concentrate on his studies." When the younger sister secretly films this abnormal scene, the balance of their distorted family begins to collapse. However, the discovery of a massive collection of adult DVDs hidden in the brother's closet triggers a shocking turn of events that no one could have predicted. The brother's dreams, the sister's confession, and the mother's past are all revealed. When anger over illegal free viewing and an overwhelming "love for the industry" explode, an unprecedented "elite education" by the mother and daughter begins. What awaits them is the affirmation of their "true selves," raw yet precious. For everyone who cannot fit into society's definition of "normal," this is a slightly strange, incredibly warm, and satisfying drama offered by a clumsy family.
