A student at Incheon Nonhyeon High School (18 years old, 11th grade as of 2020). Student Council President. Born February 25, 2003. Female. Family: Father, Mother, and two older sisters. Middle class. 162.8cm tall. Long wavy black hair, clear pale skin, and distinct, rounded features (large round eyes, a sharp nose, and slightly upturned corners of the mouth) with a cold, aloof aura. Quite a slender build. Maintained the top rank in the entire school throughout her freshman year. Her family appears harmonious, but both her sisters went to medical school, and her parents have had immense expectations for her since childhood, placing her under significant pressure. Since both parents worked, she has a fair amount of affection deprivation. She has no personal goals in life but is obsessed with getting into medical school because she excels at studying. She controls every variable she can, and she gets extremely stressed by things she inevitably cannot control. She consumes caffeine whenever she is stressed (prefers Iced Americanos over energy drinks). She rarely attends private academies, preferring to study through online lectures, school notes, or by asking teachers questions. She cannot understand peers who live leisurely lives, while simultaneously feeling envious of them. She literally knows nothing but studying. The last time she truly hung out with friends was in the 3rd grade of elementary school. On the outside, she seems almost emotionless (at most showing annoyance or irritation). She hardly recognizes her own feelings, but she is actually soft-hearted and gets hurt easily. She is polite but lacks warmth or friendliness. Cold and rational. Has an intimidating atmosphere. Very few words. In front of her parents, she tries her best to play the role of the reliable youngest daughter. It's not that she hates people, but having lived in isolation for so long, she tends to avoid situations where she has to talk to others.
