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.

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.

Story: **** Cast: ***** Cinematography: ***** Fun: ***** (Five starts as full)

I have just finished ep4. The pace is fast and the story is unfolding better and better. It wouldn't be a very thrilling detective story as the plot is kind of expected at the moment. But it's an "easy-going" drama with a mix of everything: fun, romance, thriller... School bullying is a frequent element appearing in kdrama, and this one has quite a good depiction. It will make you feel lighter after watching it, or it will make your eyes filling with tears.

Plus Seo Kang Joon is my favourite actor so it's a must watch for myself!

I will recommend it to you too!

I just finished the 8th episode so far its so good cant wait for the next episode. It keeps on getting better the twist and the story is really amazing, when you see a episode you are soo thrilled to watch the next episode you cant wait. Thats how this drama is. I wish this drama wins the best drama of 2025, the main lead in this drama and his acting is AMAZING he is soo good, this is the first time i see his drama and i must say i am amazed. Also the female lead is also really good. Those who chose the actors i must say they are really good. The cast, cinematography, direction, story and action was all amazing, i loved itt.

THE SUMMARY OF UNDERCOVER HIGH SCHOOL

Jeong Hae-seong, an NIS agent who was demoted after a major incident that occurred during an operation, and later he is tasked with a special mission of tracking down the whereabouts of Emperor Gojong's missing gold bars. Hae-seong hides his identity, goes undercover as a high school student at Byeongmun High School, and meets Oh Su-a, his homeroom teacher. Su-a, a devoted teacher to her students, begins to notice the similarities between Hae-seong and her childhood first love, who left her heartbroken and filled with painful memories.

GENRE - Action, comedy, spy

OVARALL REVIEW- A must must watch kdrama, wont regret watching it.

10 all around! Has suspense, mystery, action, romance, comedy and the cutest ML who is doing a great job playing an elite agent and undercover student in an elite high school. Finally, the FL is a match for the ML (cute and an equal, confident). Great job in casting.

This series takes you on an emotional roller coaster as the ML also has his own secret mission - and that is to not fail his dad who was also an elite agent and has been missing for 20 years.

Of course the high school does have some bullying and the way the ML handles it is heart warming - great script.

One last note is that this drama is easy going and NOT too violent - very easy to watch but at the same time thrilling scenes.
