In 2007, fifteen-year-old Chaeyoung is diagnosed with anorexia and committed to a mental hospital. Feeling guilty, her mother, Sangok, tries to trace the source of her daughter’s illness but there is no way to know. Ten years later, the mother and daughter begin a conversation. Relying on Chaeyoung’s diary, drawings, and voice-over, the film explores the history of conflict and pain in mother-daughter relationships through three generations: grandmother, mother, and daughter.
