Obsessed with Heo Nam-jun as cold-hearted chaebol heartthrob in My Royal Nemesis? His darker K-drama roles are next level

Heo Nam-jun is currently riding a massive wave of popularity thanks to My Royal Nemesis, where his cold, calculating chaebol character Cha Se-gye has become one of the drama's biggest talking points.

Villain type: Cold-hearted chaebol / emotionally controlled heir



Cha Se-gye is a third-generation chaebol heir known for his icy demeanor, strict self-control, and emotionally detached personality. He lives a life defined by discipline, precision, and power, carefully keeping his emotions buried beneath a calm and calculated exterior. Even when faced with chaos around him, he remains composed, unreadable, and difficult to approach, making him both intimidating and magnetic to those around him.

Character: Kim Sang-hyuk

Villain type: Cold-blooded antagonist / murderer



In Your Honor, Heo Nam-jun takes on one of his darkest roles as Kim Sang-hyuk, the violent and unpredictable son of a powerful crime boss.

The role stands out as one of his most memorable villain portrayals, showing a completely unfiltered and dangerous side of his acting range.


Character: Kang Seok-chan

Villain type: Morally grey survivor / Special Forces soldier



In the apocalyptic world of Sweet Home, Heo Nam-jun plays Kang Seok-chan, a Special Forces soldier forced into extreme survival situations.
