Omg fun :) and realistic. No rosey glasses here

The ML is super charming, spunky, cheery guy and that comes out in his role, he is GREAT.
FL is a little ... stupid, unfortunately the script wasnt nice to her... The actress is pretty and she did the best she could..

The story is realistic, and the actions are realistic. People who fight, get hurt. At the end, the NIS agent becomes a school teacher...

Undercover High School: A Perfect Blend of Comedy, Romance, and Thrills

I absolutely loved "Undercover High School"! The main characters were fantastic, and their chemistry was one of the highlights of the show. Each actor fit their role perfectly, making the relationships feel natural and engaging. The story was well-paced and easy to follow, with just the right balance of lighthearted moments and suspenseful twists. I found the plot above average in terms of thrills, keeping me interested without ever feeling too heavy.

The comedy was genuinely funny and never felt forced, adding a refreshing touch to the overall narrative. The romance was also well-developed, with sweet and believable interactions between the leads that made me root for them throughout the series. Overall, "Undercover High School" is an enjoyable watch that blends comedy, romance, and a bit of mystery in just the right proportions. Highly recommended for anyone looking for a fun and engaging drama!

Brilliant and refreshing! but deserved more romance...

humor, originality , suspense, thriller and friendship!! brilliant drama that perfectly blends humor with thrilling plot twists, sweet romance with blood chilling mysteries and heartfelt friendships with found family. I love it overall and found it very refreshing!! I even cried in several points of it, because I was moved by the story or by the relationship Hae Song had with the students 🥹🥹 I never felt the need to skip, it was very very enteirtaing and I got attached to all of the characters so much. The story was insanely good written and the plot gripping!! too bad the romance was only hinted at for 11 episodes... I think for this drama to get 9.5 it would have needed more romance and for it to get 10 it would have needed more episodes!!!

Be Mesmerized by Seo Kang Jun and Don't Think Too Much

The leads were adorable (Seo Kang Jun is anime pretty), and the villainess was delectable. When I shut off my brain, I enjoyed the story; I just had to quit noticing things like the professional, intelligent agent meeting a known traitor alone in a deserted spot without notifying the team. The story of hidden gold was serviceable, but Seo Kang Jun was the sole reason for the high ratings; he can do action, comedy, and romance.

Just Laugh & Enjoy

When an elite NIS agent is forced to pose as a student, his assignment becomes more tricky after several misunderstandings with his Korean history teacher. He’s determined to solve the case + solve the mystery surrounding his father’s disappearance; she’s desperate to become a full-time faculty member & be a good teacher. Will they keep getting in each other’s way & stay “rivals” or will they discover an ally in one another?

This has both heart & humor; mystery & action; villains & heroes. There’s the cruel reality of bullying & the toll it takes. There’s the heartbreaking loss of a parent. There’s the bonds of found family. There’s the beauty of reunited childhood “loves”.

The cast did their roles really well. They made us root for the good guys & detest the bad ones. Loved the students’ stories & character growth. And kudos to the mega villainess - her ability to portray such a psychotic woman deserves a round of applause. 👏🏻

Overall I enjoyed this drama. My one complaint would be that I wanted more romance between the Leads. They’re both such great actors that it felt like such a wasted opportunity that we didn’t actually get them as a couple until the last scenes so they just felt more like buddies. Regardless, though, it’s still a good watch.

A bad mix of mystery, action and comedy

Honestly, I found the drama a bit disappointing, as its comedic potential was often overlooked in favor of mystery and action. While the comedic moments, particularly those featuring O Su-a or the NIS team, were entertaining, the focus on mystery and action felt misplaced. At first, there was a sweet romance between the two main characters, Seo Kang Joon and Jin Ki Joo. However, their relationship often felt like it was less important than the main plot. Some of the supporting characters weren't very interesting, and the antagonist didn't have much depth. The mystery quickly became predictable, which resulted in the later episodes being less engaging, culminating in a rushed and unsatisfying ending. The drama did have its brighter moments, despite these flaws. The dynamic between the male lead and his team provided some of the most enjoyable scenes, showcasing genuine friendship and teamwork. And when the balance of action and comedy was just right, it was genuinely entertaining. Ultimately, this drama demanded a certain suspension of disbelief and proved to be light, chaotic, and undemanding if you chose not to overthink it. However, it just didn’t deliver on its promise of a cohesive and engaging story.

Quiznos

Kim Shin Rock absolutely stole every single moment she appeared in throughout the show. Whenever she was on screen, I could not pull my eyes away. Her intensity was electrifying, and the way she played off the hero made every interaction feel charged with energy and weight. By the end, I realized I was actually rooting for her instead of the lead, which caught me by surprise. I enjoyed the entire experience far more than I expected. Oddly enough, now I have this sudden craving for Quiznos.

Seo Kang Joon finally puts his good acting to use!

seo kang joon returns to the little screen with a bang! and what a comeback!

this drama started good and ended up great. it’s not life changing nor will it blow your mind, but it’s the perfect pick me up if you’re in the mood for some genre mixing feel good drama. it doesn’t take itself too seriously, but it’s propelled by strong performances, a fun soundtrack and great action scenes. the plot is actually super well thought out and unique, in a way.

i loved this! definitely recommend if only to see seo kang joon return in a (finally!!!!) good drama. please keep it coming kang joon-ah, we need to see your hazel eyes and great acting way more than we currently do.

A Good Treasure Finding Tale

Just a good old fashioned treasure finding story. A mystery abounds in trying to use clues to find the treasure. Along the way the ML falls in love with a helpful (and smart) damsel. There are plenty of bad guys and one sinister femme fatale who put kinks into the treasure hunting. There are twists and turns, a mystery to solve, teenage drama, overly comedic scenes, and plenty to keep you tuned in. This is good 'ol Kdrama at its finest.

Loved the actors!! The casting director really got the right actor in the right part. It is just entertainment in its purest sense. This reminds me of one of the first Kdramas I watched, and why I got hooked on Kdramas in the first place. Try it. I guarantee you'll enjoy it if you are just looking to be entertained.

A Gripping Blend of Action, Emotion, and Social Commentary

The drama's centered around Jeong Hae Seong, an NIS agent who goes undercover at an elite high school to track down a hidden national treasure. It has a mix of suspense, emotional storytelling, and strong social themes that kept me hooked from start to finish.

What I Liked:

1. Strong, Multi-Layered Characters
Jeong Hae Seong is such a compelling lead. He’s not just an action hero. He’s vulnerable, haunted by his own past with school bullying, and constantly evolving. His relationship with Oh Su A, a teacher having it rough at workplace too, adds an emotional heartbeat to the story. Their slow-burn relationship was great.

2. A Well-Woven Plot with Unique Twists
The whole treasure hunt tied into ghost stories was so clever. The mystery is built up with care, and each episode drops just enough clues and twists to keep you engaged.

3. Thoughtful Social Commentary
This isn’t just a spy-thriller. The drama digs into the toxic school hierarchy, bullying, and corruption, all rooted in real social structures. It doesn’t sugarcoat things.

4. A Solid Supporting Cast
Everyone added depth and complexity to the story.

What Could’ve Been Better:

1. Too Many Tropes
Just way too many tropes.

2. Character Choices
Hae Seong and Director Kim (not together) both made decisions at some point which threw me off. It wasn’t a dealbreaker, but it did pull me out of the story now and then.

3. Romance Left Me Wanting More
There was definitely chemistry between Hae Seong and Su A, but the romantic payoff felt a little rushed. A few more meaningful scenes could’ve made it even more satisfying. Hey, I'm not mad at it but if you were looking for an intense romance tied into the plot, this isn't it.

There were other things to play on our emotions with. It has a gripping plot, and real-world themes. While not perfect, it’s a powerful story that’s both entertaining and thought-provoking. If you're into dramas with action, mystery, and meaningful character growth, this one’s definitely worth your time.

Would I recommend it?
Yes, especially if you love undercover plots with heart and a touch of romance.

Strongest as a mystery thriller treasure hunt. Unbearable as a Romcom

None of the promo materials that I saw indicated this was a treasure hunt, which makes it so much more interesting that the undercover highschooler teacher romance, which is as creepy as it sounds whenever the story dipped into that plot line that also grinds the pacing to a halt. It is the worst part of the show which unfortunately means more often than not the female lead who is the teacher in the equation is the worst part. She is a terrible teacher not noticing the actual bullying occurring in her classroom while being extremely violent with the male lead who she thinks is a teenager and violating boundaries by showing up at his house on short notice. Once she learns he's NIH undercover, both of their brains go out the window. They are always out drinking together or touching hands, they are just courting a student teacher scandal.

The treasure hunt however is quite interesting, I really enjoy the clues being hidden in tales of ghostly hauntings that also mirror the real life school bullying of Hae Jeong and his classmates. The villain of the treasure hunt storyline is amazing. She is both cunning and unsettling that other kdrama villains think they are. The way she picks apart her daughter's self esteem, what she does with a steak knife to her own wrist in front of her daughter who freaked out at the photoshoot refusing to expose her scarred wrists, what she quotes about a slavery era book. Her daughter being cruel to Hae Seong's sister who just accepts it in order to be kind to the girl she saw with the scarred wrists. Later when she beats up a kid in the rest room who badmouthed her daughter in front of her and she chastises him to watch his mouth around elders while banging her own head on the mirror is so unhinged.

The romance is so forced, the drama would have been stronger without it. The secondary romance was also terrible and never funny even though it was supposed to be comic relief moments. The spy versus mastermind dynamic between Hae Jeong and Myeong Ju is so much more electric to see . I don't know if it's because I just didn't catch it, but I didn't see any specific branding on the sandwich shop until ep 4, which is a funny mini background mystery until it's revealed to be Qiuznos. The end where Hae Jeong points a gun at Myeong Ju only to hand it over to the same woman clearly having a dangerous mental health episode where she's already threatening the entire class of kids with oil and fire, was ridiculous. He's otherwise smart enough most of the time. I like that he clocked the principal truly caring about Myeong Ju and Ye Na and urged him not to enable her anymore.

The treasure hunt ending in Hae Jeong getting closure in finding out what happened to his father is meaningful. It's lovely that the cute little star motif between him and his father leads him to the gold his dad hid. All of his classmates showing up at his father's funeral was sweet. He got to remake his high school experience that was so terrible he got a GED instead the first time. His adopted father and son relationship with his uncle is also really sweet. I loved the moment he supported his decision to quit high school and was the one suggesting the GED. His annoyance at the thought that his adopted sister Yu Jeong may become his colleague is funny because he was colleagues with his adopted dad. Though there were still elements that I enjoyed, the momentum of the mystery and the pacing of the story really fell apart towards the end. It might have been a tighter with a few episodes less.
