Who Stars In My New And Only CEO?

Kim Soo-hyun and Park Bo-young headline 'My New and Only CEO,' and their performances are pure magic. He’s all sharp suits and sharper wit; she’s radiant and resilient. The ensemble cast—especially Lee Dong-hwi’s comedic timing—adds layers to every episode. It’s a show that makes you believe in love and power suits.

Oh, 'My New and Only CEO' is one of those dramas that sneaks up on you—I went in expecting a typical office romance but got totally hooked by the chemistry between the leads. The main couple is played by Kim Soo-hyun and Park Bo-young, who bring this adorable mix of tension and warmth to their roles. Kim Soo-hyun nails the cold-but-vulnerable CEO vibe, while Park Bo-young’s character is all sunshine and determination. Their dynamic reminds me of classic rom-coms like 'What’s Wrong with Secretary Kim,' but with a fresher, more modern twist. The supporting cast, including Lee Dong-hwi as the chaotic best friend and Jung Eun-ji as the sassy coworker, adds so much flavor to the story. Honestly, it’s the kind of show where even the minor characters feel fully realized—I found myself rooting for everyone by the end.

What really stood out to me was how the actors balanced humor and heart. There’s a scene where Kim Soo-hyun’s character tries (and fails) to cook for Park Bo-young, and it’s equal parts hilarious and tender. If you’re into K-dramas that blend workplace shenanigans with genuine emotional depth, this one’s a gem. I binged it over a weekend and still replay my favorite moments in my head.

If you’ve seen Kim Soo-hyun in 'It’s Okay to Not Be Okay,' you know he can switch from icy to vulnerable in a heartbeat—and he brings that same range to 'My New and Only CEO.' Park Bo-young matches him step for step; her character’s optimism isn’t naive but hard-earned, which makes their romance feel grounded. The supporting cast shines too, especially the office gossip squad (shoutout to Kim Sun-young’s scene-stealing cameos). What I love is how the show avoids clichés—no amnesia, no evil exes—just two people figuring out love while juggling corporate chaos. The writing’s sharp, too; episode 7’s elevator confession had me grinning like an idiot. It’s the kind of drama that leaves you warm and fuzzy, like a hug in TV form.

I’m a sucker for romantic comedies, and 'My New and Only CEO' totally delivered. The casting is perfection—Kim Soo-hyun as the brooding, perfectionist CEO and Park Bo-young as the plucky employee who turns his world upside down. Their on-screen spark is electric, and the way they play off each other’s strengths makes every scene crackle. Lee Dong-hwi steals every scene he’s in as the CEO’s mischievous childhood friend, and Jung Eun-ji’s deadpan humor is a riot. The show’s got that rare balance of witty dialogue and heartfelt moments, like when Park Bo-young’s character stands up to Kim Soo-hyun in a board meeting—it’s empowering without feeling preachy. Plus, the soundtrack slaps; I still hum the theme song while doing dishes.
