Honestly, if you haven't rewatched the cast of What's Wrong with Secretary Kim lately, you're missing out on a masterclass in rom-com energy. It’s 2026, and while the K-drama world has moved on to high-concept thrillers and AI-driven plots, there is something about the 2018 lineup of this show that just... stays.
You know that feeling when a show’s casting is so perfect it feels like lightning in a bottle? That’s this one.
Most people talk about the "Park-Park" couple—Park Seo-joon and Park Min-young—but the magic of this show actually lives in the weird, quirky corners of the office. The supporting cast didn't just fill space; they carried the comedy on their backs.
The Power Duo: Park Seo-joon and Park Min-young
Let’s be real. Park Seo-joon as Lee Young-joon is basically the blueprint for every "arrogant but secretly traumatized" CEO we’ve seen since. He managed to make narcissism look kinda charming? Not many actors can pull off saying "Aura!" while basking in their own reflection without making the audience cringe.

Then you have Park Min-young. She didn't just play a secretary; she defined the "Secretary Kim" aesthetic. Those pencil skirts and silk blouses literally sparked a fashion revolution in offices across Asia. But more than the clothes, it was her "straight man" comedy. She played it so cool against Young-joon’s chaos.
Their chemistry was so intense that people still dig for evidence that they were dating in real life. They weren't (as far as we know!), but that’s just a testament to how well they worked together.
The Office Crew: Where the Real Comedy Happened
If you only watched for the leads, you missed the best parts. The Yumyung Group office was a fever dream.

- Kang Ki-young (Park Yoo-shik): The MVP. The best friend. The guy who was constantly giving relationship advice while his own marriage was a dumpster fire. Kang Ki-young has since become a massive star (remember him in Extraordinary Attorney Woo?), but this was the role that proved he’s the king of comedic timing.
- Hwang Bo-ra (Bong Se-ra): She was absolutely unhinged. In the best way. Her facial expressions alone deserved an award. She played the over-the-top, boy-crazy section head with so much heart that you actually rooted for her weird romance with the quiet bodyguard.
- Hwang Chan-sung (Go Gwi-nam): The frugal king. Seeing a member of 2PM play a guy who only owns one suit and lives on the roof was the kind of subversion we love.
- Pyo Ye-jin (Kim Ji-ah): She was the rookie, the audience surrogate. Pyo Ye-jin has gone on to lead huge dramas like Taxi Driver, but here, she was just a girl trying to survive her first week without getting fired.
Why the Cast of What's Wrong with Secretary Kim Matters Now
Look, K-dramas in 2026 are great, but they can be a bit heavy. This cast reminds us of a time when the stakes were just "will she quit her job?" and "why is he so full of himself?"
The show worked because the cast of What's Wrong with Secretary Kim committed 100% to the bit. They didn't wink at the camera. They played the absurd scenarios with total sincerity. When Kang Hong-suk (the bodyguard Yang Cheol) started singing to Se-ra, it wasn't just a joke; it was a Moment.
What Most People Get Wrong
People think this was just a "pretty people" show. It wasn't. It was a technical achievement in ensemble acting. If one person had played it too serious, the whole thing would have collapsed.

The Legacy of the 2018 Cast
Most of these actors are now "A-list" leads. Park Seo-joon is in the Marvel Cinematic Universe. Park Min-young is the undisputed queen of office rom-coms. Kang Ki-young is a household name. Seeing them all in one room back then feels like looking at a "Before They Were Famous" gallery, even though they were already stars.
