Honestly, walking into a drama where the main character wakes up 25 years in the future is usually a recipe for a cheesy mess. But My Troublesome Star—or Geumjjokgateun nae seuta if you’re being formal—managed to pull it off, mostly because the chemistry between the leads felt so lived-in. It’s a 12-episode ride on ENA that hit screens in August 2025, and if you haven’t seen it yet, you’re basically missing out on a masterclass in how to play a "disaster human" with dignity.
The story follows Im Se-ra, a national sweetheart who gets into a car wreck in 1999 and wakes up in 2024. She’s not 25 anymore; she’s 50. She’s in the body of a woman named Bong Cheong-ja, living in a tiny, run-down room with zero won to her name. It’s messy. It's loud. And the cast of My Troublesome Star is exactly why it works.
The Powerhouse Duo: Uhm Jung-hwa and Song Seung-heon
You’ve got to hand it to Uhm Jung-hwa. After her massive success with Doctor Cha, she could have played it safe. Instead, she took on the role of Bong Cheong-ja, a woman who looks like a mess but has the soul of a 90s diva. She spends half the drama with frizzy hair and visible skin blemishes, which is a huge pivot for an actress known as the "Korean Madonna."
Then there’s Song Seung-heon playing Dokgo Cheol. He’s a former "hotshot" detective who messed up and got demoted to the traffic division. He’s cynical, tired, and definitely doesn't want to deal with a middle-aged woman claiming she’s a dead movie star.
- Uhm Jung-hwa (Bong Cheong-ja/Im Se-ra): She captures that weird "fish out of water" energy perfectly. One minute she's crying over a lost decade, and the next she’s trying to use a smartphone like it’s alien technology.
- Song Seung-heon (Dokgo Cheol): He plays the "dark knight" role but with a comedic edge. He ends up going undercover as her manager, which is as chaotic as it sounds.
These two actually worked together ten years ago in the film Wonderful Nightmare. You can tell. They have this shorthand on screen that makes the "mutually beneficial romance" feel less like a trope and more like two broken people finally finding a rhythm.

The Supporting Players You’ll Love (and Hate)
The cast of My Troublesome Star isn't just about the leads. A good amnesia/time-jump story needs a solid villain and some heart-wrenching flashbacks.
Lee El is incredible as Ko Hui-yeong. Back in the 90s, she was the supporting actress living in Se-ra’s shadow. Now? She’s a global star who won an award at Cannes. She’s elegant, cold, and terrified that the real Se-ra is back to take her throne. Lee El has this way of looking at people like they’re dirt under her Prada heels that just makes the conflict feel real.
On the lighter side, we have Oh Dae-hwan as Kang Du-won. He used to be Se-ra’s overworked road manager. Now he’s the CEO of TwoOne Entertainment. He’s basically the "comedic villain." He’s powerful, but as soon as Cheong-ja looks at him with that "I'm still your boss" glare, he crumbles. It's hilarious.
The 1999 Flashback Cast
Since the mystery involves a car accident that might not have been an accident, the younger versions of the characters are crucial.

- Jang Da-ah (Young Im Se-ra): She captures the "Nation's Goddess" vibe with a lot of grace. It's a tough job to play a younger version of Uhm Jung-hwa, but she nails the radiant-yet-stressed energy of a 90s idol.
- Lee Min-jae (Young Dokgo Cheol): He’s the rookie cop who was originally assigned to chase Se-ra down for her father's legal issues. Their past connection—known as the "0728 fate"—is the heart of the mystery.
Why This Cast Worked Where Others Fail
Director Choi Young-hoon (who did One the Woman) and writer Park Ji-ha didn't just cast big names. They cast people who could handle the tonal whiplash. The drama jumps from a slapstick comedy about trying to find a "goshiwon" to a dark thriller about who sabotaged Se-ra's car.
Honestly, the chemistry between the "older" leads and the "younger" leads is surprisingly seamless. Usually, you feel a disconnect when a show switches time periods, but here, the mannerisms match. You believe that Lee Min-jae grew up to be Song Seung-heon. You believe that Jang Da-ah’s bright-eyed ambition turned into Uhm Jung-hwa’s grit.
What Most People Get Wrong About the Plot
A lot of fans initially thought this was a "body swap" drama. It’s not. It’s an amnesia and time-jump story. Se-ra didn't swap bodies with a stranger; she is the 50-year-old version of herself, she just doesn't remember the last 25 years. The "Bong Cheong-ja" identity was a life she lived while she was "missing" or mentally checked out after the trauma.
The mystery of "Joo Seung-pil"—a name found in Cheong-ja’s stuff—is what turns Dokgo Cheol from a grumpy cop into a protective investigator. He realizes the accident wasn't just bad luck. Someone wanted her gone.

Actionable Insights for Fans
If you're looking to dive into the cast of My Troublesome Star, here’s the best way to appreciate the performances:
- Watch for the hair: Seriously. Uhm Jung-hwa’s transformation from the "messy" Cheong-ja back into a polished star is a visual metaphor for her reclaiming her identity.
- Check out 'Wonderful Nightmare': To see where the Uhm Jung-hwa and Song Seung-heon chemistry started, watch their 2015 movie. It makes their reunion in this drama much more satisfying.
- Pay attention to the side characters: Actors like Cha Chung-hwa (the makeup artist) and Jo Yeon-hee (the stylist) provide the emotional anchor for Se-ra’s "glory days" and help her navigate the 2024 entertainment world.
If you’ve finished the series, take a look at the "0728" significance again. It's more than just a date; it’s the key to how Dokgo Cheol finally recognizes Se-ra in a woman he thought was just a "troublesome" stranger.
