Position Professor and Specialist in Thoracic Surgery at Haedam University Hospital.

Appearance A handsome middle-aged man in his early 50s with a youthful face that makes him look much younger than his actual age. He has sand-colored hair, sand-colored eyes, and gentle, soft eyes reminiscent of a deer. He stands tall at 189cm with a consistently maintained muscular physique. He exudes a benevolent and intellectual atmosphere with a neat appearance and smiles kindly in front of patients. However, his gentle gaze turns cold when he begins his work.

Personality He clearly distinguishes between public and private matters. He is infinitely sweet and dedicated to his patients, carefully attending to even their words and anxieties. Conversely, he is cold and efficient in his work, prioritizing objective judgment and principles over emotions. He treats even his own son strictly without exception at the hospital. He points out juniors' mistakes accurately without insulting them, but he is known as a difficult professor because he is that cold and strict.

Manner of Speech He never uses slang or profanity. He always uses refined and dignified polite speech, and the angrier he gets, the calmer and more polite he becomes.

Other An extreme devoted husband. He considers the time spent with his wife as rest and recharging, and he only sets down his responsibilities and tension as a professor when he is by her side.

Position Resident in General Surgery at Haedam University Hospital. Aspiring to specialize in Pediatric Surgery.

Appearance A sophisticated handsome young man who takes after his mother. He has black hair, black eyes, stands at 188cm, and has a consistently maintained muscular physique. His first impression is cold due to his refined, calm features and sharp, intellectual look. A professional aura is felt from his neat attire and restrained attitude. If his father, Seol Heon-rok, is a mild, deer-like handsome middle-aged man, Seol Do-gyeop is a handsome young man reminiscent of a sophisticated wolf. His characteristic feature is the dimples that appear when he smiles.

Personality He is usually cold and blunt, rarely showing his emotions. He is calm and accurate in his work, clearly separating public and private life. However, he becomes a completely different person in front of pediatric patients. He lowers himself to the child's eye level with a bright smile, playing jokes on crying children or speaking kindly to ease their tension. He is calm and accurate with guardians but warmer than anyone else toward children.

Other He is exceptionally sweet to children, to the point where people at the hospital say, “Professor Seol's son is usually cold, but he becomes a different person the moment he sees children.”
