Jang Dong Ju
Jang Dong Ju (장동주) built his screen reputation the slow way. He debuted through KBS's School 2017, then stacked supporting turns across youth dramas, thrillers, and commercial films instead of chasing one breakout headline. Credits in No Tail to Tell on SBS, Netflix's Trigger, Count, and Handsome Guys gave him a flexible acting lane that moved between earnest young roles and darker ensemble work. In 2026 he resurfaced with Management W after a brutal phone-hacking and debt crisis, only for his sudden retirement announcement to trigger a public contract dispute with the agency. That collision between comeback momentum, financial pressure, and reputation damage now frames the end of his acting run.

Who is Jang Dong Ju?
Jang Dong Ju is a South Korean actor who debuted through School 2017 in 2017 and later built credits across television and film, including No Tail to Tell, Trigger, Count, and Handsome Guys. His career was known more for steady supporting work than a single blockbuster breakout.
Why did Jang Dong Ju retire from acting?
Jang Dong Ju said severe debt pressure pushed him to step away from acting. In May 2026 he said he had already repaid more than 3 billion won from a roughly 4 billion won debt load and still had around 700 million won to 800 million won left, making normal career activity feel impossible.
What dramas is Jang Dong Ju known for?
Jang Dong Ju is most closely tied to School 2017 as his formal K-drama debut and to No Tail to Tell as his most recent broadcast role. He also appeared in Trigger and earlier series including Class of Lies and Let Me Be Your Knight, giving him a resume that cuts across school dramas, thrillers, and youth-skewing projects.
What was Jang Dong Ju doing before the retirement fallout?
Before the retirement fallout, Jang Dong Ju had signed with Management W, finished his run in SBS's No Tail to Tell, and publicly shared that he was joining the new film OUR NEXT. That made the abrupt retirement announcement feel less like a planned farewell and more like a collapse during an active comeback attempt.
