Some doctors win you over with bedside manner. Others win you over by being so good at their job that the whole hospital goes quiet. Gye Soo Jung, played by Kim Ji Won in SBS’s upcoming “Doctor X,” is firmly in the second camp. New stills released on September 29, 2026 show both sides of her: the fierce surgeon and the eccentric human.

Meet Gye Soo Jung: Fierce and Fun
Gye Soo Jung is unfazed by the power structure at Guseo University Hospital. In the operating room, her skill is overwhelming. Outside it, she’s eccentric yet down-to-earth, a contrast that makes her far more interesting than the usual cold genius. The new stills capture that split personality well.
Kim Ji Won’s First Time as a Doctor
This is Kim Ji Won’s first role as a doctor, and she didn’t take it lightly. She learned the movements needed for real surgical scenes from the show’s medical adviser and took plenty of time to get comfortable with them.
The effort seems to have paid off. Director Lee Jung Rim said it was hard to imagine anyone else in the role, praising how she moved between Soo Jung’s commanding side and her human side. The director also shared that the on-set doctors serving as medical advisers applauded her surgical scenes. That’s high praise from the real experts.
What Her Co-Star Says
Lee Jung Eun, who plays Jang Hee Sook, also had kind words. She said eye contact and acting with Kim Ji Won made emotional lines come together naturally, and called her an actress of tremendous depth.
