Mère de Sujin is a minor character in the anime True Beauty, featured primarily through the background and trauma of her daughter, Kang Sujin. In the original webtoon and its anime adaptation, she is depicted as an alcoholic and abusive mother who contributes to the collapse of the family after the arrest of her husband, Sujin’s father. Her behavior is characterized by neglect and verbal or physical mistreatment, which deeply affects Sujin’s emotional well‑being and drives much of Sujin’s later insecurities, including her desperate need for external validation and her tendency toward antagonistic behavior. The mother’s own motivations are not explored in the story; she functions largely as a negative influence in Sujin’s life rather than as a developed figure with her own arc. Her key relationship is the strained and harmful dynamic with her daughter, which contrasts sharply with the more supportive families of other main characters. Within the narrative, she appears in a few brief scenes, often criticizing Sujin’s choices or financial habits, and her role is confined to being a source of Sujin’s domestic hardship. There is no notable character development or display of particular abilities for Mère de Sujin; she remains a static, off‑screen or peripheral presence whose primary function is to illustrate the difficult home environment that shapes Sujin’s personality and life choices.
