Kang You-seok

Kang You-seok (강유석) did not arrive as an overnight breakout. He spent years building screen range in smaller parts before the industry finally had to treat him like a lead-calibre actor. That slow build matters because his recent rise looks earned: the looseness in his comic timing and the control in his dramatic work both come from reps, not hype.

His wider public jump came through Netflix's Black Knight and accelerated again when 2025 put him in front of larger mainstream audiences through tvN's Resident Playbook and Netflix's When Life Gives You Tangerines. Those projects pushed him from promising supporting actor into the premium-series conversation.

Now Kang sits in a strong cross-platform lane. JTBC, tvN, Netflix, and Disney+ are all part of the current credit picture, which is exactly the kind of spread that signals long-term staying power in Korea's drama market.
