Reseñas

This review may contain spoilers
Buena historia
El drama plantea una buena historia, la manera en la que todo se desarrolla es muy entretenida e interesante. La manera en la todo fue un plan de la misma villana para encontrar el oro lo hace muy intrigante. Podría decir que pudieron haber dejado esa parte en los capítulos finales para no perder la emoción de la historia. Lamente un poco que el punto máximo de la villana se haya visto explotado casi al final, hubiese querido verla de esa manera desde el principio. Al final todo resultó muy bien¿Te ha parecido útil esta reseña?

Seo Kang Joon Carries This Drama (And We Let Him)
You know those dramas that make zero sense if you think too hard, but somehow, you’re still entertained? Yeah, Undercover High School is exactly that. It throws logic out the window, packs in a little bit of everything—action, mystery, comedy, school drama, romance—and hopes you just roll with it. And honestly? For the most part, I did.The biggest reason this drama works (or at least stays watchable) is Seo Kang Joon. He completely steals the show, bringing so much charisma and depth to a character that could have easily been just another over-the-top "cool undercover agent" trope.
Now, about the plot... Well, let’s just say realism was not invited to this party. It feels like the writers grabbed a bunch of random drama clichés—childhood connection, undercover operation, high school bullying, a missing treasure (??), and a cartoonishly obsessed villain—and mashed them all together. There were moments where I was genuinely invested, but also moments where I just had to sigh and accept the nonsense.
The romance? It was sweet but definitely felt secondary. Jin Ki Joo was cute in it, and her chemistry with Seo Kang Joon felt natural, but her character was underdeveloped. She had her own motivations and backstory, yet they didn’t explore them enough. Instead, the drama focused more on the school setting, which—while important—took up too much time, leaving other elements underdeveloped.
Kim Shin Rok’s acting was great in this—she brought intensity to every scene.
Speaking of which, the central conflict… sigh. They started off promising, but by the end, their actions were so ridiculous that it was hard to take them seriously.
That said, I did love the dynamic between the ML and his team. Their friendship and teamwork brought some of the most enjoyable moments. The action-comedy balance was a hit-or-miss, but when it hit, it was really fun.
Final Thoughts:
If you’re watching this for a strong, well-structured plot—this is not the one. But if you want something light, entertaining, and filled with Seo Kang Joon moments, then go for it. It’s the kind of drama where you don’t think too much, just sit back and enjoy the ride. It’s a fun, chaotic watch—flaws and all.
