Kim Ji Won’s “Doctor X” Teaser Unveils a Brilliant, Dangerous Surgeon Unlike Any Other

A surgeon who never fails — but might not be entirely who she claims to be. That’s the intriguing hook behind SBS’s upcoming medical noir “Doctor X,” which just dropped a gripping new teaser starring Kim Ji Won, and K-drama fans are already buzzing about it.

Based on the hit Japanese series of the same name, the show follows “Doctor X” Gye Soo Jung (Kim Ji Won), a genius surgeon who operates on a deeply corrupt medical establishment using nothing but pure, unmatched skill.

“Doctor X”: Key Details

A Graduation Oath With a Twist

The newly released teaser opens with Gye Soo Jung reciting the Hippocratic Oath — but not in the way you’d expect. While her fellow medical school graduates stand together in the auditorium, she takes the oath alone, standing before a mysterious figure and declaring, “On my honor and of my own free will, I swear all of this as a doctor.” It’s an unusual, isolating moment that immediately raises questions about her hidden past.

Skilled, Fearless, and Possibly Dangerous

From there, the teaser escalates fast. Gye Soo Jung is shown performing surgery without a moment’s hesitation, even as tense, dangerous scenes unfold around her — including a moment where someone appears to choke her mid-scene. Text overlays describing her as “the most dangerous doctor” and questioning whether she’s “completely obsessed with surgery” only deepen the mystery around her character.

By the teaser’s end, hospital director Boo Seung Kwon (Son Hyun Joo) quietly asks the question the entire show seems built around: “Is Gye Soo Jung Doctor X?” It’s a cliffhanger clearly designed to keep audiences guessing about her true identity — a storytelling approach that echoes the moral ambiguity often explored in medical drama as a genre.
