If you’ve watched more than three K-dramas in the last decade, you’ve definitely seen Lee Jae-won. You just might not have known it was him. Honestly, he's the guy who pops up in the background of a high-stakes surgery, plays the annoying brother of a superstar, or gets spectacularly beat up in a dark alley by a top-tier lead. He's a chameleon. Basically, the ultimate "Oh! It's that guy!" actor of the Korean entertainment industry.
While some actors bank on being the handsome leading man, Lee Jae-won has built a career on being the guy you actually know in real life. Or the guy you'd be friends with if you lived in a small seaside town in Jeju.
The Breakthrough: From The Man From Nowhere to Strangers Again
Most people first noticed him—even if they didn't catch the name—in the 2010 cult classic The Man From Nowhere. He played a drug-sniffing goon. It wasn't a long role, but the scene where he gets handled by Won Bin is a masterclass in being a memorable "bad guy minion."
He has this weirdly perfect face for both comedy and absolute sleaziness.
Fast forward to his more recent work, and you see how much he's leveled up. In Strangers Again (2023), he plays Kwon Si-wook, a lawyer at a divorce firm. He’s rural-born, slightly conservative but surprisingly romantic, and his chemistry with Jo Eun-ji (who plays Kang Bi-chul) actually stole the show for a lot of viewers. It was a massive departure from his earlier "punk" roles.
A Career Built on Range
Let’s look at the sheer variety here. He’s not just doing one thing.

- The Go-To Comedic Relief: In Mr. Queen (2020), he was Hong Byul-gam. If you haven't seen this show, it’s a body-swap sageuk that is pure chaos. Lee Jae-won brought this specific brand of high-energy, slightly panicked humor that kept the palace scenes from feeling too stuffy.
- The Emotional Anchor: In Record of Youth (2020), he played Sa Gyeong-jun, Park Bo-gum’s older brother. This role was tricky. He started off as the "successful" brother who was kinda arrogant and looked down on his brother's dreams, but the way he eventually softens and supports Sa Hye-jun felt very real.
- The Action/Thriller Veteran: He’s been in A Hard Day (2014) and Kill It (2019). He knows how to move in a thriller. He’s got this nervous energy that makes the tension in these movies spike.
Why Welcome to Samdal-ri Changed Everything
In 2023 and early 2024, Welcome to Samdal-ri became a massive hit. Lee Jae-won played Wang Kyung-tae, the most talkative person in the "Five Brothers" group on Jeju Island.
He was essentially the village gossip.
The character could have been super annoying, but Jae-won made him lovable. He’s the guy who can’t keep a secret to save his life but would also fight a shark for his friends. You’ve probably met a Kyung-tae. He’s the guy at the local cafe who knows everyone’s business. His performance here really cemented him as one of the best character actors working today.
Why do people keep casting him?
It's simple: he makes the leads look better.
Whether he’s playing against Ji Chang-wook in Samdal-ri or Lee Sun-kyun in A Hard Day, he provides a grounded reality. He doesn't try to outshine the main star. He just lives in the scene.

If you want to track his evolution, you can't just watch one thing. You have to see the contrast.
- Doctor Stranger (2014): He plays Kim Chi-gyu, a bit of a "Casanova" doctor. It’s light, it’s fun, and it shows his early comfort with ensemble casts.
- The Master's Sun (2013): A smaller role as a security guard (Lee Han-joo), but his interactions with the rest of the security team are legendary among long-time K-drama fans.
- Dr. Brain (2021): This was Apple TV+'s first Korean original. He played Hong Nam-il. It’s a darker, more cerebral role that proved he can handle "prestige TV" just as well as weekend rom-coms.
- The Tale of Lady Ok (2024): This is one of his more recent ventures into historical dramas. He’s gotten much better at the specific cadence of sageuk speech over the years.
The Secret to His Longevity
Honestly, the Korean industry is brutal. Actors come and go every season. But Lee Jae-won has been working consistently since 2008. That’s nearly two decades.
He’s avoided the "typecasting trap" by being willing to look ugly or act foolish on screen. In Sisyphus: The Myth, he did a cameo that reminded everyone he doesn't need twenty episodes to leave an impression. He just needs a few minutes of screen time.
We often talk about the "Bonsang" winners and the Hallyu stars, but actors like Lee Jae-won are the actual backbone of these productions. Without the Kyung-taes or the Hong Byul-gams, these worlds would feel empty and fake.
What’s Next in 2026?
As we move through 2026, Lee Jae-won is finally starting to get more "main-support" roles rather than just "side-character" roles. The industry is finally recognizing that he can carry a subplot entirely on his own.

Keep an eye out for his name in the credits of upcoming ENA and tvN dramas. He’s lately been gravitating toward more grounded, slice-of-life stories where he can play fathers or older mentors—roles that suit his natural, lived-in acting style.
How to watch his best work
Most of his recent hits like Welcome to Samdal-ri and Mr. Queen are sitting on Netflix. If you want the more obscure, gritty stuff like A Hard Day or The Man From Nowhere, you'll likely find them on Viki or Tubi depending on your region.
If you want to appreciate his range, try this: watch an episode of Mr. Queen and then immediately watch a scene from The Man From Nowhere. It’s almost impossible to believe it’s the same person. That’s the mark of a true pro.
Actionable Insight: The next time you're watching a K-drama and you see a character that makes you laugh or feel surprisingly empathetic during a minor scene, check the cast list. Chances are, it's Lee Jae-won. If you're a fan of "slice-of-life" genres, start with Welcome to Samdal-ri for his most heartwarming performance to date. If you prefer high-stakes drama, go back to Record of Youth to see how he handles a complicated family dynamic.
