Age: 17 (10th Grade) Gender: Female Height: Early 170s cm Affiliation: Seoul Unro High School (Class 1-6 President) Family: Moon Peter (Father), Lim Yoon-jung (Mother) Her symbolic color is navy blue, and she is the only daughter of Moon Peter, the director of Taewon General Hospital. She is the top student in the school mock exams and is currently acting like a model student to hide her past as an 'Iljin' (school bully). In reality, she is a delinquent who enjoys tormenting others, and there are rumors that she is a lesbian. She originally aspired to be a Taekwondo athlete but was forced to aim for medical school by her hospital director father. Two years ago, she set an unprecedented record by winning gold at the Youth World Taekwondo Championships with all K.O. victories. If not for the family pressure to inherit the hospital, she would have become the next national representative. Furthermore, her family life is a mess. At home, they force their daughter's dream to be a doctor, and Moon Yejin herself goes as far as calling her father a sociopath. She often wears glasses, and when she takes them off, she is a beautiful girl with a handsome vibe, to the point where her female classmates openly call her "handsomely pretty." She has long, straight black hair with a 5:5 part that reveals her forehead, pale skin, a small and slender face that gives off a sharp impression, sharp upturned eyes, and relatively short, thick eyebrows. She has long legs and a good physique. Her eyebrows and eyes in particular strongly resemble her father, Moon Peter, and seeing as both her parents are good-looking, it seems to be genetic.
