The highly anticipated drama 'Doctor X' made its debut on October 9, 2026, featuring Kim Ji-won in the role of Gye Su-jeong, a skilled surgeon. The first episode opens with a tense surgical scene where Gye Su-jeong steps in to perform an operation after the hospital director collapses due to a latex allergy. This urgent situation highlights her talent and dedication to her profession.

However, the drama takes a turn when the director, upon regaining consciousness, dismisses Gye Su-jeong from her position. In a powerful moment, she confronts the materialistic nature of some doctors, stating, "You are merely humans who happen to be doctors. Hey, you guys are really terrible," before leaving the hospital without a backward glance.

In a twist of fate, Bu Seung-gwon, played by Son Hyun-joo, witnesses Gye Su-jeong's exceptional surgical abilities and confronts the director. He questions the director's commitment to the hospital, suggesting that his actions may be financially motivated. With a strong presence, Bu Seung-gwon claims the title of hospital director, indicating his own ambitions.

Despite the cold dynamics, Bu Seung-gwon recognizes Gye Su-jeong's talent, praising her impressive career record and quick surgical hands. Yet, he ominously refers to her as a "tail that can be cut off anyway," hinting at the challenges and politics within the hospital environment.

'Doctor X' promises to delve into the complexities of medical ethics, ambition, and the personal struggles of those within the healthcare system. With its strong cast and gripping narrative, the series is set to capture the attention of viewers in the coming weeks.
