Kang Sang Jun
Kang Sang Jun (강상준) is part of a familiar Korean-acting story: years of steady craft before the larger industry finally starts paying closer attention. He first built his base in musical theater, then carried that stage discipline into television and film work where his appeal sits less in flash and more in emotional stability.
That slow climb is why his recent stretch matters. Projects including Marry My Husband, Dear Hyeri, and Flex x Cop gave him supporting visibility across different tones, but Azure Spring feels like a real step-change. In the series, Kang plays Yoon Deok-hyun opposite Yeri of Red Velvet, a role positioned around healing, secrecy, and romantic tension rather than simple supporting utility.
Represented by Cré Company, Kang now sits in an interesting lane: old enough to bring lived-in texture, still fresh enough to read as a breakout. If Azure Spring lands, it should move him from strong-recognition actor to a name that audiences start actively tracking.
