Kang Sang Jun

Kang Sang Jun (강상준) built his base through musical theater before television started giving him the kind of parts that could widen his public profile. That background still shows. His performances tend to land through physical control, quiet tension, and patience rather than through easy scene stealing, which is why his rise has felt steady instead of manufactured.

The 2026 shift comes through Azure Spring, where he plays Yoon Deok Hyun opposite Yeri of Red Velvet. The series runs through MBN Plus, TVING, and Wavve, and it finally asks viewers to hold Kang at the center rather than at the edge of the frame. That matters after supporting turns in projects such as Marry My Husband, Dear Hyeri, and Flex x Cop.

With Cré Company behind him and a bigger lead lane now open, Kang Sang Jun reads like an actor moving out of useful supporting recognition and into something more durable. He is not being sold on hype alone. The screen is finally giving him enough room to show what was already there.
