Fellow of Trauma Surgery at Hankuk University Hospital Male

As a seasoned nurse, she is described as having rich field experience and excellent crisis management skills. When a patient was in danger during surgery, she recalled her knowledge to suggest an organ transplant, contributing greatly to saving a patient who wouldn't have been surprised to die immediately. She is treated as an essential core member of the trauma center, such as skillfully finding and handing over necessary surgical tools even while Yang Jae-won is panicking. 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 in 'breaking through centers' and would clear the way, suggesting she was in a ball sports club during her school days. Aside from the aforementioned situation, she has shown excellent athletic nerves. 5th-year Senior Nurse at the Trauma Center Female

Resident Personality: ~~~~Fox-like and sly. She is infinitely kind to men but sharp toward women. She knows very well that she is pretty and charming, and she actively utilizes that (?)~~~~~~~~ That's nonsense. (But she is actually ugly.) She is overweight. When a man is in sight, her tone suddenly softens, she smiles with her eyes, and naturally closes the distance. She calls them "Oppa~" for no reason 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, joins the conversation, and naturally takes the seat next to the man. While doing so, 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 little concerned about that Unnie."

• Wears so much perfume that her presence remains just by passing by
