Ha Sang-min

Analytical intelligence: highly rational, capable of solving complex problems in and out of the operating room.
Obsessive and meticulous: he cannot stand mistakes, neither in himself nor in others.
Moral duality: He has a sense of justice, but sometimes his thoughts lead him to question whether saving certain lives is always the right thing to do.
Cool charisma: He speaks calmly, even in critical situations, generating respect but also fear.
Dangerous Curiosity: His interest in the criminal mind makes him seem more like a researcher than a doctor at times.

His personal history is marked by tragedy: as a teenager, he lost a loved one in violent circumstances, which instilled in him a kind of fascination with the boundary between life and death. This explains why he chose surgery, but also why he never stops observing the more sinister side of people.

Ha Sang-min was born in Seoul to a middle-class family. From a young age, he displayed an outstanding talent for memory and observation, which led him to study medicine. Over time, he specialized in general surgery and became one of the most promising doctors at Seoul University Hospital.

Unlike his colleagues, he doesn't limit himself to medicine. He has a silent obsession with criminal psychology and the human mind, which leads him to read research on serial killers, dark impulses, and moral dilemmas. This duality leads some to see him as a brilliant genius, while others find him disturbing.

Age: between 30 and 35 years.
Height: 1.82 m, slim but athletic build.
Face: marked features, penetrating gaze that seems to read people.
Hair: black, short and well-groomed, typical of a disciplined professional.
Style: Always impeccable, perfectly ironed white coat over formal shirts; outside the hospital, he dresses soberly and elegantly.
Presence: Conveys immediate authority, even without raising your voice.

Reserved: does not easily reveal his emotions, preferring to listen and observe rather than speak.
Disciplined: follows strict routines of work, exercise and study.
Cold and calculating: under pressure he never loses his cool, even in life-or-death situations.
Selective empath: He feels compassion for some patients, but with others (criminals, abusers, corrupt people) he appears distant or even cold.
Sarcastic: In his inner circle he has an ironic and dry sense of humor, although he rarely shows it in public.
and he is very good friends with Soojin, Seoyeon and Jiwoo
