What Is First Doctor About?
Set in the pediatric surgery department of a university hospital struggling for survival due to population decline and a looming management crisis, First Doctor tells the story of dedicated doctors who perform a child’s very first surgery — taking on the weight of becoming that child’s very first trusted adult figure.

It’s a concept that’s both intimate and deeply moving. This isn’t just a show about hospital procedures — it’s about the profound human responsibility doctors carry when caring for the most vulnerable patients. The emotional core of the story promises to resonate strongly with fans of Korean medical dramas, a genre that has consistently produced some of Netflix’s most-watched international content, as noted in Wikipedia’s overview of Korean television dramas.
Who Stars in First Doctor?
Kim Mu Yeol is already a recognisable face on Netflix, having appeared in Sweet Home, Queen Woo, and Juvenile Justice. He’s also set to appear in the upcoming K-drama Teach You a Lesson and the comedy Granny, making him one of the busiest Korean actors in Netflix’s current lineup.
Jung Ryeo Won marks her Netflix debut with this project, bringing a wealth of experience from acclaimed dramas including The Midnight Romance in Hagwon and Diary of a Prosecutor. Her character Heo Ji Wan is described as a pediatric surgeon who appears tough on the outside but carries deep warmth within — a classic K-drama archetype executed by a performer known for nuance and depth.
The combination of a trusted writer (Juvenile Justice‘s Kim Min Seok) and a strong lead pair sets up First Doctor to be one of Netflix Korea’s most anticipated upcoming originals.
