Genius surgeons don’t always stay serious once the cameras stop rolling. SBS’s upcoming medical noir drama *Doctor X* just dropped a behind-the-scenes teaser, and it shows lead star Kim Ji Won swapping her character’s steely composure for genuine laughter and playful moments with her co-stars.

### What the New Doctor X Teaser Reveals?

*Doctor X* is based on the popular Japanese series of the same name and follows Kim Ji Won as Gye Soo Jung, a brilliant surgeon who lets her skill speak for itself while exposing corruption within the medical establishment. The new making-of clip splits its focus between the cast’s dedicated on-set work and the lighter, more candid moments captured between takes.

Despite her character’s intense, no-nonsense demeanor, Kim Ji Won appears relaxed and cheerful off camera, sharing a warm hug and even a playful dance with co-star Lee Jung Eun, who plays Jang Hee Sook, the head of a medical staffing agency. Meanwhile, Kim Woo Seok, who takes on the role of surgical intern Park Tae Kyung, adds to the anticipation with a confident, camera-ready thumbs up.
