Doctor X: Lee Jung Eun’s Jang Hee Sook Hides a Sharp Schemer Behind Her Easygoing Charm, Premiering Oct 9

Every great heroine needs a great ally, and Doctor X may have found a scene-stealer. SBS has released new stills of Lee Jung Eun in character, and her role looks like the perfect mix of humor and hidden cunning. Here’s what the images and behind-the-scenes comments reveal.

Doctor X : Overview

Who Is Jang Hee Sook?

Lee Jung Eun plays the money-driven head of a medical staffing agency, the person who sends Gye Soo Jung to Guseo University Hospital. She isn’t a surgeon, which makes her an unusual character in a medical drama. Instead, her power comes from connections, instincts, and a knack for reading people.

On the surface, Jang Hee Sook seems talkative and materialistic. Underneath that easygoing exterior, though, she’s a shrewd schemer who uses her sharp instincts to maneuver through the hospital’s power struggles. That contrast is what makes her intriguing: a character who looks casual but is always calculating. She’s expected to bring both humor and tension to the story.

The Relationship to Watch

The most interesting dynamic may be between Jang Hee Sook and Gye Soo Jung. On paper, they’re business partners bound by a contract. In practice, they’ve grown close enough to look out for each other like family, much like an aunt and her niece. They bicker and clash regularly, but when it really counts, they always have each other’s backs. That mix of squabbling and loyalty adds a warm, funny layer to an otherwise dark medical noir.

What the Team Says?

Kim Ji Won singled out Lee Jung Eun’s unpredictable performance as a highlight and teased that there’s a big action scene for Jang Hee Sook. That’s an unexpected promise for a character who runs an agency instead of an operating room. Director Lee Jeong Rim described the character as someone who keeps revealing new sides, to the point where you find yourself wondering what else she can do.

Why It’s Worth Watching?

Doctor X follows a genius surgeon who fights a corruption-ridden establishment with pure skill, and a strong supporting cast can make that world feel richer. With Jang Hee Sook adding wit and scheming, the show has a chance to balance its heavy themes with personality.

The drama premieres October 9. In the meantime, you can watch Lee Jung Eun in A Hundred Memories on Viki. For more previews, browse our K-drama updates and entertainment news on Technosports.
