Lucifier? Batman? Whatever, Ahn Bo Hyun is a star of his own.
Not every show needs to be a masterpiece. Every now and then, there are dramas like this that don’t try to be groundbreaking. They just focus on doing what they’re meant to do–entertain. Do you remember those cartoons you used to enjoy as a kid? The kind where each episode had its own little adventure, wrapped up neatly by the end? Flex X Cop feels exactly like that– simple, straightforward, but oddly satisfying. It’s the kind of show that keeps you coming back, episode after episode, just because it’s fun to watch. It was a genuinely enjoyable journey following this chaebol-turned-cop as he searched for his purpose in life, and from episode one, it had my full attention.
I’ve got to start with the dynamic between the two leads, because that’s really what carries the show for me. The relationship between Jin Yi Soo (Flex Cop) and Lee Kang Hyun (Lady Cop) was surprisingly well-written and genuinely well-crafted. It just felt... natural. Nothing about their interactions came off as forced or overly scripted, which is impressive considering how cliche the overall drama can be at times. Watching them slowly get to know each other, episode by episode, felt like watching two real people grow closer, organically and without any unnecessary drama. I’m a huge fan of that slow, subtle development that blossoms over time. There’s something undeniably addictive about their back-and-forth dynamic; it’s got a kind of Tom and Jerry charm that keeps me coming back. Huge kudos to the writers for not shoving a romance subplot down our throats. Honestly, I think they work better as frenemies than lovers. Camaraderie over romance, any day.
I know this is a detective-mystery-crime-themed show, but I’d urge you not to go into it with that as your main focus. It plays out more like a series of mini-cases that gradually build toward the overarching mysteries surrounding both leads' parents. As for the crime-solving and case-related mysteries, they’re pretty basic, nothing groundbreaking, but still engaging enough to keep you watching. I wouldn’t call the cases boring, but they definitely don’t feel like the main course. The villains aren’t genius masterminds, the cases lack depth or complexity, and the twists aren’t particularly hard to predict. Honestly, it felt more like an extended version of the Mafia Game—nothing too intricate, but fun in a “just play along” kind of way. The murderer is usually right there in plain sight, so don’t overthink it and just enjoy the ride. Most of the cases will seem tailored to make JYS shine, thanks to his inherent advantages as a rich, influential online celebrity and chaebol heir as his unfair advantage. While that does feel a bit like cheating, I actually didn’t mind it. It was genuinely entertaining watching him pull it off, and more than anything, I found myself rooting for him.
I also appreciate how the show doesn’t waste time with unnecessary fluff or try too hard to be overly emotional or complex. Instead, it trusts the story to unfold naturally, revealing answers at just the right moments. The pacing and development here are honestly some of the better ones I’ve seen. It’s consistent, steady, and never drags. It’s the simple, fundamental things like this that the show really gets right. Flex X Cop maintains its momentum in a straightforward, unpretentious way, and to its credit, it actually gets better as it goes.
That said, like I mentioned from the start, this is far from a masterpiece and the flaws are pretty glaring. Even though I didn’t go into it expecting much, there were still moments so absurd they felt like outright lazy writing, making them hard to overlook. I mean, I was supposed to believe JYS could hypnotise a doctor who specialises in hypnosis? Or that he could crash a helicopter into the back of a car without injuring a single person? And then there’s the invisible drone. Seriously? Some of the events that helped solve cases left a bitter aftertaste because of how ridiculous they were. He also somehow becomes the only person capable of magically pulling clues out of thin air, despite being the rookie play-cop on the team. On top of that, any scene without the two leads together took a noticeable dip in quality for me; those parts just felt flat and uneventful. By the later episodes, even the chemistry that initially hooked me started to lose its spark, and I found myself less invested. The hype definitely fizzles out toward the end, probably because there’s just not enough substance at the core of the drama. I’m no longer rushing to watch new episodes as soon as they drop—but it’s also not bad enough for me to completely drop it either.
Amidst the influx of shows with amazing casts in recent weeks, Flex x Cop was a really pleasant surprise. It was something light that I do not feel compelled to follow tightly weekly but good enough for me to pick it back up sometime in the week for a decent time. It does have a little bit of everything you want in a drama. Would I recommend it? Not really. Will you enjoy it if you still decide to watch it? I think very likely so.
**My favourite scene in the show that lives rent-free in my head till today: Jin Yi Soo whipping out a gold crafted handcuffs because he was not allowed to carry a gun…and Kyunjin playing along with him by getting arrested…also that slap might be one of the most satisfying slaps in I have seen in K-drama...I replayed that whiplash of a slap many many times...
