Netflix is about to deliver another powerhouse drama, and honestly? We can’t wait. “First Doctor” is assembling an all-star cast that promises nothing but excellence. Let’s dive into what makes this medical drama unmissable.

First Doctor: The All-Star Cast Lineup

Actor	Character	Role Description
Jung Ryeo Won	Heo Ji Wan	Dedicated pediatrician returning to her former hospital
Ha Yun Kyung	Ki Eun Gyul	Senior surgical resident, initially skeptical of change
Kim Moo Yul	TBD	Major supporting role (details coming soon)
Baek Hyun Jin	Professor Son Sang Baek	Head of surgery with shared history

What’s the Story About?

Imagine being a talented doctor who had to leave her dream department on the worst terms possible. Now, “First Doctor” follows Heo Ji Wan, a dedicated pediatrician who returns in triumph to Yeonhee University’s pediatrics department—only to face colleagues who remember exactly why she left.

The real magic happens when she meets Ki Eun Gyul, a brilliant surgical resident whose skills are legendary. Initially skeptical of Ji Wan’s plans to overhaul the system, Eun Gyul gradually becomes won over by her professionalism and genuine care for patients. That’s the human drama that makes medical stories unforgettable.

Why This Drama Screams Quality

Director Hong Jong Chan has a proven track record with critically acclaimed Netflix series like “Juvenile Justice” and “Teach You A Lesson.” This marks his third collaboration with Kim Moo-yul—a partnership built on trust and creative synergy. When you’ve got that kind of history, you know the final product will be exceptional.

Plus, Jung Ryeo-won and Ha Yun-kyung? These actresses bring depth to every role. Their on-screen dynamic will be electrifying.
