I’m actor SEO DONG JAE. I’ve built a solid track record across film and major series on Disney+, Netflix, JTBC, SBS, tvN, and Coupang Play, playing a wide range of grounded, character-driven roles—from business owners and executives to officials and everyday neighbors. Known for quick character comprehension and dependable on-set reactions, I help shape the rhythm of a scene and strengthen the story with focused, memorable supporting work.
