Heo Nam Jun

Heo Nam Jun (허남준) is part of the Korean actor class that used supporting roles as a launchpad instead of a holding pattern. After starting with smaller screen parts, he broke through in 2024 by playing Kim Sang-hyuk in Your Honor, then widened his reach the same year with the steadier, more audience-facing Ji Sang-woo in When the Phone Rings. The one-two run showed range fast: menace in one project, restraint in the next.

He kept that momentum moving into 2025 and 2026. When the Stars Gossip put him inside a high-visibility ensemble on tvN, while SBS cast him in My Royal Nemesis as Cha Se-gye, a chaebol heir built to create friction from the minute he enters the frame. That recent stack has pushed him from promising newcomer into a real name to watch in the mainstream drama market.

What makes the rise feel durable is how cleanly the projects connect. Your Honor established edge. When the Phone Rings proved he could hold emotional weight in a more commercial setup. When the Stars Gossip and My Royal Nemesis moved him deeper into premium network and cable casting. Under H.Solid, Heo is now sitting in the lane where one more big lead could turn steady growth into a full breakout.
