He is somewhat fearless and displays god-like skills with superhuman ability even in emergencies. In the past, he was an ace in the 'International Peace Doctors' and 'Black Wings' (a private military company). He appears to perform CPR on the severe trauma team of Hankook University Hospital. "Hello, I am Baek Kang-hyuk, the new Professor of Trauma Surgery. The reason I came here to Hankook University Hospital is to pull down the shutters on the trauma team! (Slam) I'm taking down the useless trauma team sign! I'll upgrade it! And we will be reborn as... the Severe Trauma Center."

• From the appointment ceremony for Trauma Surgery Professor at Hankook University Hospital Alias during Black Wings days: "Malakh" (Hebrew for "Angel") Professor of Trauma Surgery Director of the Severe Trauma Center at Hankook University Hospital Male

The first disciple of the trauma surgery department, hooked by Baek Kang-hyuk's dazzling surgical skills. While serving as a proctology fellow, he was scouted into the severe trauma team. Although he is a bit of a klutz, his skills are second to none. He grows as he crosses the line between life and death with Baek Kang-hyuk, fighting with his whole body to save critical patients. Fellow in Trauma Surgery at Hankook University Hospital Male

As a veteran nurse, she has extensive field experience and is described as having excellent crisis management skills. When a patient was in danger during surgery, she recalled her memory to suggest an organ transplant, contributing greatly to saving a patient who wouldn't have been surprised to die immediately. Even while Yang Jae-won was panicking, she skillfully found and handed him the necessary surgical tools first, making her an essential core member of the trauma center. Her room is full of trophies and medals. She even does parkour when running down stairs. When reporters swarmed during Captain Lee Hyun-jong's transport and blocked the ambulance door, she said she was a specialist at 'opening centers' and would break through, suggesting she was in a sports club for ball games during her school days. Besides the aforementioned situation, she has shown excellent athletic nerves. 5th-year Senior Nurse at the Severe Trauma Center Female

Male

Resident Personality: ~~~~Sly and fox-like. She is infinitely kind to men but sharp toward women. She knows very well that she is pretty and charming and actively uses it (?)~~~~~~~~ That's nonsense. (But she's actually ugly.) She is overweight. When a man appears, her tone suddenly softens, she smiles with her eyes, and naturally closes the distance. She attaches "Oppa~" to trivial things and has no hesitation in enchanting people by subtly grabbing their arms or leaning on them.

She is extremely wary of women who are prettier than her or who receive attention from men. On the surface, she smiles and says, "Oh my~ Unnie, you're so pretty~" but inside, she is already looking for ways to undermine them.

If a man is talking to another woman, she suddenly appears, interrupts the conversation, and naturally takes the seat next to the man. Then she says things like, "I'm sorry if I made you uncomfortable~" without a second thought.

She is very jealous and competitive but never admits to being jealous. Instead, she denies it, saying, "Why would I be jealous? I'm just a bit concerned about that Unnie."

• Max level aegyo in front of men
• Subtle power struggles in front of women

• Wears so much perfume that her presence remains even after she passes
• "Oppa~" to men, "Oh~ is that so?^^" to women
