Whether you’re a longtime fan or watching Nam Joo-hyuk for the first time, these seven dramas offer the perfect introduction to his career-defining roles.

Who Is Nam Joo-hyuk?

Before becoming one of Korea’s most recognizable leading actors, Nam Joo-hyuk started his career as a fashion model in 2013. His natural screen presence soon opened the door to acting, and he made his television debut with The Idle Mermaid in 2014. Over the years, he has impressed audiences with his ability to move effortlessly between heartwarming romance, emotional coming-of-age stories, and intense action dramas.

What makes Nam Joo-hyuk stand out is his willingness to take on completely different characters instead of staying within a single genre. From the determined Baek Yi-jin in Twenty-Five Twenty-One to the ambitious Nam Do-san in Start-Up and the fearless Kim Ji-yong in Vigilante, each role highlights a different side of his acting. After completing his mandatory military service, he returned with The East Palace, adding another major project to an already impressive filmography.

7. The Light in Your Eyes (2019)

What if you could turn back time, only to lose something even more precious? That’s the emotional question at the heart of The Light in Your Eyes.

Nam Joo-hyuk delivers a calm and heartfelt performance as Joon-ha, bringing warmth and quiet vulnerability to a character who feels remarkably real. His chemistry with the cast adds depth to a story filled with hope, heartbreak, and unforgettable moments.

I placed this drama at No. 7 because it isn’t the easiest watch for everyone. Its slow pace may not appeal to viewers looking for fast-moving romance or action. That said, if you enjoy emotionally rich stories with meaningful character journeys, this drama rewards your patience in a truly unforgettable way.

Every successful actor has a breakthrough role, and for Nam Joo-hyuk, Who Are You: School 2015 was that turning point. Set in a competitive high school, the drama follows identical twin sisters whose lives unexpectedly become intertwined after a tragic incident. As secrets begin to unfold, friendships are tested, emotions run high, and a heartfelt love triangle keeps viewers guessing until the very end.
