Korean Drama '' Undercover High School '' is a school mystery thriller with a strong comedic element.
The story is not that original, but the mystery is, and the comedy part was well handled, with enough funny scenes to lighten the mood. The mystery was also intriguing, it was well paced, and had smooth twists.
The romance, on the other hand, could have been omitted, as it didn't really add anything to the plot, and was half baked in the end, as the drama opted to focus more on the mystery, thankfully, and not on the love story.
Finally, the performances were all great by everyone in the cast.
So, overall, eight out of ten.

I'm so so sad that this show is j 12 eps, it deserves 20 eps. I finished this show a week ago and i already have the urge to rewatch it again.
The story line, the dialogues and delivering chaotic energy in such a non-cringe and natural way i loveeed it istg. So so so good. I love chaotic shows and the element of the NIS agent to this show j makes it sm hotter for me alr istg.
I had actually never heard of seo kang joon before, but brothers and sisters i am already obessed w this man. He is so underrated i don't get why. His acting is so so so natural loved it. His character was so manly but pookie which is absolutely loved. What i love the most is eyes istg. The most beautiful eyes i have ever seen on a man to date, im not even kidding.
Jin ki joo, i love her too. Her character was so cute, i wanted to keep her in my pocket literally. Even she herself as an actress phenomenal and again so underrated.
The chemistry between jeong hae-seong and oh su-a was insane. Believe me when i tell you even their hands had chemistry.
Love this show, lowkey wanna lose all my memories and watch this masterpiece again.

It's been a while since a series hooked me this much. I've been eagerly waiting each week for new episodes and didn't feel disappointed even once.
Great blend of different genres - action, adventure, comedy, romance and all of them so well written. Jin Ki-joo and Seo Kang-joon truly brought their characters to life and their chemistry is of the charts.
There is many kdrama cliches in the story which I often find bothersome but they are so well introduced that felt very natural.
The main story is fast paced and I wish there was more time to dive into some dinamics between characters or side stories but I guess it was impossible with 12 ep.
Overall a must watch!

Action, thriller, comedy, romance, mistery, high school bullying, everything in there but written with competency and beeing serious about bullying. The series is about golden bars hidden in the high school and the NIS agent (Seo Kang Joo) had to find them going undercover as a student. His teacher (Jin Ki Joo in a hilarious excelent performance) mistrust him and try to unmask him causing very funny consequences. There are three NIS agents who support Seo Kang Joo who make his mission not so easy. The villain in the series is the Principal (Kim Shin Rok who is become specialized in villain character) That is a very entertaining series and recomend it.
