You know that feeling when you're watching someone complain about doing their job, but they’re doing it so efficiently that you can’t help but be impressed? That is basically the entire brand of Lee Seo Jin. Whether he’s dragging a suitcase across Europe for a group of legendary actors or obsessing over the profit margins of a Korean street food stall in Mexico, the man has turned "grumpy competence" into a high art form.
Honestly, it’s a bit of a miracle. In an industry where most stars are desperate to seem bubbly and approachable, Lee Seo Jin is refreshingly... not. He’s the guy who graduated from NYU with a business degree and somehow ended up as the "Nation’s Porter." If you’re looking for a watchlist, you’ve got to navigate two very different worlds: his intense, dramatic history as a leading man and his legendary status as the reluctant king of reality TV.

The Variety Evolution: From Porter to President
If you haven't seen Grandpas Over Flowers, you’re missing the origin story of modern Korean variety. It’s arguably the most important of the tv shows with lee seo jin because it changed how we see him. Back in 2013, Na Young-seok (the famous Na PD) essentially tricked Lee Seo Jin into a trip to Europe, telling him he’d be traveling with girl group members.
Instead? He got four veteran actors in their 70s and 80s.
Lee Seo Jin spent the next several seasons as the "luggage boy," navigating maps, booking hotels, and making sure the "halbae" (grandpas) were fed and happy. He grumbled the whole time, but he never actually let them down. It’s that tsundere energy—cold on the outside, warm on the inside—that made him a household name for a whole new generation.
The Restaurant Empire
Then came the cooking shows. It started with Youn’s Kitchen, where he served as the hall manager under the legendary Youn Yuh-jung. He took it way too seriously. He was constantly checking the accounts and worrying about the inventory. This eventually evolved into his own spin-off, Jinny’s Kitchen (also known as Seojin’s).
- Season 1 (Bacalar, Mexico): He brought in heavy hitters like Park Seo-joon, Choi Woo-shik, and V from BTS. Watching him stress over whether they sold enough gimbap while V just wanted to go for a swim is peak entertainment.
- Season 2 (Reykjavík, Iceland): The stakes got higher and the weather got colder. He was promoted to CEO, and the pressure of running a successful spicy oxtail soup spot in Iceland really brought out his inner business mogul.
The 2025-2026 Shift: My Grumpy Secretary
Most recently, he’s been killing it in a show called My Grumpy Secretary (sometimes translated as Seojin's Butler or Secretaries). He teamed up with his real-life best friend Kim Kwang-kyu. They basically act like a bickering old married couple while they "manage" other celebrities. It premiered late in 2025 and immediately topped the variety charts on Netflix in Korea. If you want to see him at his most unfiltered—literally just roasting his friends while providing "close-up care" for stars like Eom Ji-won—this is the one to watch.

The Dramas: Before the Dimples Went Viral
Before he was the guy with the whisk and the passport, Lee Seo Jin was a serious dramatic heavyweight. It’s easy to forget because he’s so funny in variety, but the man has some serious acting range.
Damo (2003) is the one that really started it all. It’s a "fusion" sageuk (historical drama) that was way ahead of its time. He played Commander Hwangbo Yoon, and his chemistry with Ha Ji-won was so intense it created a literal syndrome in Korea. People were obsessed.
Then you have Yi San (2007). He played King Jeongjo. This wasn't just a hit; it was a 77-episode marathon that cemented him as royalty in the industry. If you want a more modern, tear-jerker vibe, go for Marriage Contract (2016). He plays a cynical rich guy who enters a fake marriage with a terminally ill single mother (played by Uee). It sounds like a total cliché, but their performances are so grounded that it actually works.
Recent Scripted Work
He hasn't completely abandoned acting for variety.
- Dr. Park’s Clinic (2022): He went full comedy here, wearing a bald cap to play a struggling doctor. It was a huge risk, but it showed he doesn't take himself too seriously.
- High School Return of a Gangster (2024): A bit of a weirder one where his character’s soul ends up in a high schooler’s body.
- Uncle Vanya (2026): Just recently, news broke that he’s making his theatrical debut in May 2026 in this Chekhov classic at the LG Art Center. It’s a huge deal because it's his first time on stage in 27 years.
Why People Actually Watch Him
There’s a specific "Lee Seo Jin vibe" that's hard to replicate. He’s wealthy, well-educated, and clearly doesn't need to be doing these shows, which gives him a level of honesty you don't usually see on TV. When he says a guest is annoying or the food is bad, you believe him.
He’s also the ultimate professional. In Three Meals a Day, he’d complain about having to cook outside over a fire, but then he’d spend six hours perfecting a loaf of bread in a makeshift stone oven. He hates the process but loves the result. That’s relatable.
Your Lee Seo Jin Watchlist Strategy
If you're new to his work, don't just dive in randomly. You’ll get whiplash. Start with the "Reluctant Guide" era and move toward the "CEO" era.

- The Hook: Start with Grandpas Over Flowers. Watch the first season in Europe. It explains his entire personality.
- The Binge: Watch Jinny’s Kitchen Season 1. The chemistry between him, Park Seo-joon, and Choi Woo-shik is the gold standard for celebrity friendships.
- The Tear-Jerker: If you want a drama, skip the 70-episode epics for now and go straight to Marriage Contract. It’s 16 episodes of pure emotion.
- The Newest Hit: Check out My Grumpy Secretary on SBS or Netflix to see his 2026 energy.
Instead of just looking for "a show," look for the ones directed by Na PD. Their partnership is legendary. They’ve been working together for over a decade, and Na PD knows exactly how to push Lee Seo Jin’s buttons to get the best reactions.
Actionable Insight: If you're watching Jinny's Kitchen 2, pay attention to how he manages the "interns." It’s actually a decent lesson in micro-management and delegation, wrapped in a comedy show. For those in the US or Europe, most of his recent variety work is available on Amazon Prime Video or Viki, while his older dramas like Damo are often tucked away in the "Classics" sections of K-drama streaming sites. Keep an eye out for his stage debut in Uncle Vanya this summer—it’s likely to be the talk of the 2026 awards season.
