Top Ten Chiller-Thriller and Crime Korean Dramas

Many people in general think K-dramas are all about romance and nothing more. We all know how potential Korean romance is, and getting dizzy over feels is a common criteria for all K-drama lovers. However, there are these dramas that scoop out your soul while you're watching them, and let me remind you that these chills don't always revolve around only romance.

The Top Ten

1 Signal

I will wholeheartedly agree. This drama, I don't even have words for it. It kept me on my toes till the last end, and then...poof, I was literally left breathless, as if though I had ran a marathon. You can feel every single thing the actors are feeling. They laugh, you laugh. They cry, you bawl out. Each cases they solve, will keep you up, as if though you're in the drama and solving the case alongside them. This drama had been on my recommendation list for some time, and like many people, I was obsessing over it "to watch, or not to watch" I went EVERYWHERE looking for reviews regarding this show. But I still didn't watch it (lol) Finally, when I was out of "my type" of dramas, and the review here was my pushing edge. Then I gave it a try. Let me tell you this, I was beating myself over with the fact that I hadnt watched it earlier. Speaking of which, I think I'll have my Signal Marathon for the second time. Toodles!

THE BEST. My brother who was not a fan of korean drama even get so absorbed throughout the whole story and know he just LOVES korean drama

Mind-blowing, Amazing Plot,Will make you cry your eye balls out. Must watch.

Best Thriller korean drama.

2 Gap-Dong

Even though it's a common police-procedural drama that messes with your psychology, it is so much more than that once you advance through the episodes. There were moments when I literally shook. There were also moments I shut down my computer and couldn't watch an episode till I had recovered. Lee Joon, being an idol actor, took absolute control and amazed a lot of drama fans, moreover, shocked them. An absolutely amazing drama. And let's not talk about the killer OST that just triggers your feels. - rin2787

I'm watching it now and it keeps me questioning who is Gap Dong? I've been directed into this site because I'm looking for answers but I don't wanna spoil myself. I have to refrain from looking for answers and watch it myself till the end. I bet this is really the best crime thriller drama. I'll get back on you when I already finished watching it and have all the answers. Every episode will keep you alive.


This series leave me insane.

3 Tunnel

Great kdrama

After Signal and Voice, I continue with Tunnel and it turns out GREAT. PERFECT. If I could mention my top 5 crime-drama that would be : Tunnel, Signal, Voice, I Hear Your Voice, and War Of The Sun. All of them will never bore you.

Seriously, such a plot they have there... I'm amazed by the actors, background ost, the twists, the trust, love, stories... They're all perfect together, I'm in love. Best korean drama I've ever witnessed, it taught me a lot and still teach me. thank you Tunnel family from the bottom of my heart.

Tunnel is the best thriller drama I have watched ever.

4 City Hunter

Okay, first of all I'll be honest--getting a grip of this from the first episode was hard for me. It involves marines, political conspiracy and lots of grudges. A surviving soldier and a stolen child that he raised as a weapon of revenge combined is not your average mac and cheese. This series drained me when I watched it, made me lose my breath a couple of times, was fun, was fresh, and was oh-so-thrilling at times. And as an addition, it's not everyday you see Lee Min Ho being your under-cover vigilante slash revenge-seeker on screen. A beautiful watch. - rin2787

The Best Korean Drama of all time

Just simply amazing!

Just awesome

5 Nine: Nine Times Travel

Best travel time drama

Another TvN drama that I couldn't resist putting up. It might not be under the thriller genre, but it will thrill you, no doubt. When you add a famous news reporter who's dying and a few incense sticks that help him travel back in time, there will be drama. A man sets out to make amends to his life through this unnatural time travel method.However, the changes are devastating, and once you proceed through the episodes, you realize there's a lot of crime involved. I wouldn't really call it an exact crime drama, but it gave me chills, and probably is one of the bests out there, in fact. - rin2787

This was a fantastic time travel drama done right. I had nothing else to watch and decided to just go for it and I was so glad I did. I didn't sleep for day marathoning this. a must watch!

I love this drama to bits!

I never thought thriller K-drama would be so thrilling. It is full of mystery but in the other hand gives some clues that keep the viewer guessing who the murderer is, and how he gets away. Some stories about the main characters also lead you to analyse who is right and who is wrong. Totally interesting, yet scary, definitely must watch!

The best out of this list in my opinion.

The best KDRAMA I watched so far. Still waiting for Season 3 hihi.

I love it so damn good!

One of the best drams I have ever seen. I recommend it to everyone. It has a good plot.

Highly recommended. Superb action, suspense..good plot!

I love the whole story line and how each of the characters have their own conflicts and stories! It's definitely one of my favourite Dramas so far

This actually should be first! The whole plot is great! I needed paper to crumple throughout watching this cause you would greet your teeth by the tense that's happening. I love this!

8 I Remember You

This drama is something I would recommend to people who are new to Korean dramas or existing fans. It is also family driven, focused on a father, and two brothers. The plot and performance was tip top. I did not expect much, however it blew my mind away with the twists and turns. The story runs smoothly and it was not confusing despite the amount of information needed to make sense of the story. Although romance was not a focal point, the tiny bit of it will make you fall in love with the love between the two leads. All in all, it is a drama to watch if you are a fan of police procedural genres, and a fan of crime dramas.

This was the best in crime, bromance, slow burn romance that draws you through the tiny caring looks exchanged between the leads and understanding each other without many words. All casts played their role well. Kudos.

I admit that I am fairly new to kdramas but this one just really stood out. It's been days since I have finished watching the series and yet the story's constantly been in my mind until now. The plot is so good! It got me hooked on every episode. The actors were also amazing, everything was flawless! I didn't mind the lack of focus on the romantic relationship of the two leads at all. Kudos to the writer and the team behind this drama. Much information about psychology and police procedures was included but as one who is not familiar with any, has understood and even got interested to it. I'm having trouble searching for other kdramas now that would match up to this drama. I simply cannot move on from the impact this drama's caused me. A definite must watch!

Great story, perfect production, awesome soundtrack, plus the actors are sexy

9 I Hear Your Voice

I could easily put most of Lee Jong-Suk's dramas in my list because I am so biased by him. But this drama stood out to me. A combination of a dreadful incidence, promises, crime and fright all gathered into a courtroom drama is what I needed in my life. Did I mention the ability to read minds? He hears everyone's voice, from the depth of their souls. He even hears the minds of his most hated and most loved people. I love this drama so much, I don't even know where to put it in my list, so I'm just leaving it here. - rin2787

This is my favorite Kdrama! I Hear Your Voice is such a solid drama. The leads have great chemistry.

It's one of the best dramas I've ever watched.. There's enough romance, thriller etc all at the same time. Lee Jong Suk as usual is perfect. He was excellent.

Love this one watched it 2 times made me cry :( - nutalia

10 The Devil


I had very few expectations when I started this. But the drama really did surprise me. I don't think I have ever felt as much sympathy for the bad guy than in this. The drama questions the very nature of being bad. Who is the devil? Is the good guy really good? Is the bad guy really bad? These questions filled up my head as I watched this.

This is a classic.Not really. A 2007 drama revolving a tarot-card reader who also has some specific psychic abilities, a mysterious lawyer and a detective with regrets of his own. As usual, all these fine people are interconnected through a past occurrence. I loved this drama, and I loved watching it, I loved the chills it gave me and I loved the tears I shed for it. My love for this plot and drama would probably explain why it still exists in my list after eight years. - rin2787

The Contenders

11 Healer

A sweet romance between the leads, but it's not the love story who keeped me looking at the movie, but the characters, especially the mother and the anchor man. Great fighting scenes.

I love it!
It is so thrilling,funny and romantic. I would command to anyone

It was thriller along with romance

Best drama I have ever watched after city hunter

12 Two Weeks

I love lee jun ki after watching that drama.

This is a must watch! I watched all episodes in one go from 10am till 3am non-stop.

Another amazing plot that I haven't seen fully. Shmuck, what am I doing with my life? But according to thrill lovers, this one is a must-watch with its plot revolving around a man who has been accused of murder and has to save his dying daughter before it's too late. I can only imagine the amount of times I'd have to shut my computer down for this. - rin2787

Awesome, keeps you on the edge of your seat.

13 I Miss You

Don't you just hate those dramas that drive you insane with feels and unbearable scenes from the very first episode? No,man, you gotta love em. You gotta, at least, love I Miss You. A tragedy of two children where the boy abandons the girls and leaves her for dead in the hands of kidnappers is no mild. You need a lot of strength to watch this drama, I know I did. Heart-wrenching crime at first, and soon it's packed with thrills when the boy becomes a dedicated detective for the sake of his past mistake and swears to find the friend he abandoned. When Yoon Seung-ho is antagonizing JYJ's Mickey as the lead, you need no other reason to watch this. - rin2787

One of the most deep and thrilling kdramas I've ever watched. After watching this, other series seemed to lack depth. Definitely recommended!

Love this too

14 Wanted

Most thrilling Series I have seen Ever

One of the best korean thriller drama. Can't wait for the next episode! Love the plot.

Currently my Favourite drama now! can't wait for the next episode

15 Golden Cross

I still haven't seen this and basically am referring to the thoughts and ratings of fans, trailers and the general plot. A prosecutor gets entangled in messy business with the most influential people in Korea. He has to go against this certain circle of people to clear off his father's name who has been accused for the murder of his sister. By the sounds of it, it's going to be extremely awesome, and I want to watch it asap, and maybe it will go way up my list after I do. - rin2787

16 The Village: Achiara's Secret

The best!

I like this movie so much because actors are very handsome and greatful. Then crime is the best

I love this drama...mix emotion

To combat rising violent crimes, the Police Chief asks Detective Oh Goo-Tak (Kim Sang-Joong) to form a team consisting of criminals. Detective Oh Goo-Tak is currently suspended from the police force for using excessive force. Detective Oh Goo-Tak gathers team members: Park Woong-Cheol (Ma Dong-Seok) who is a gangster, Lee Jung-Moon (Park Hae-Jin) who is the youngest serial killer with extraordinary intelligence and Jung Tae-so (Jo Dong-Hyuk) who is a contract killer. Also, Police Inspector Yoo Mi-Young (Gang Ye-Won) joins the team.

20 38 Revenue Collection Unit

It's so good it's under rated!

One of the best dramas I've ever watched. The team chemistry is so good it's almost unreal. Really liked the story and the cast. Would absolutely recommend this to anyone who'd listen.

Really couldn't get into this was most disappointed. Gave up about episode 5 the main chief really annoyed me, he was slow over weight and dim witted. The young conman was cheesy and arrogant not to mention kept getting caught.

When I decided to take a break from Korean typical drama (romance, chaebol, etc) and gave this drama a try, it didn't disappoint me at all but now I couldn't move on instead! This drama was so good and entertaining. Every actors gave the best of them and the plot was so much interesting. You guys should watch this!

I love this drama so much! the story Itself is just amazing and with these great actors just perfect! I can just recommend it!

Intense, but very good!

This k-drama definitely intense the scene, should watch this drama that about the law and victim

I recommended this k-drama are heavy scene that about law,don't expect love scene because this is reality what we have now in this society and the government, this is my favorite so far this k-drama that you will learn about the law and being fair to people accused and using people that involve money.

22 Vampire Prosecutor

Its an awesome drama. Loved it even more than the vampire detective. A third season is definitely required. Superb acting and plot.

One of the best drama's there is! you will not be disappointed!


23 White Christmas

Best psychological korean thriller ever

Amazing! White Christmas was brilliantly written. It has a lot going. Dark mistery, thriller, rites of passage and much more. As it has plot twists and a good story, it also depicts the whole incident with a beautiful perspective of humanity. Cannot recommend enough!

Its one of those dramas which really gets your mind working. Mystery thriller drama with amazing actors, and plot twists. When you start watching, make sure to watch until the end.

A short mystery thriller, where the plot is full of mind games! Really puts you on the edge of your seat in certain episodes... A must watch for thriller mystery lovers..!

24 God's Gift: 14 Days

One of my favorite drama.. The last episode really makes me speechless..
This drama is about a mom which lost her daughter and have a chance to travel back to 2 weeks before her daughter die. With a private detective which also travel back to time, she do everything she can to find out who will kidnap her daughter and why that happen..
After watch 2 episodes, I didn't put high expectation on this drama and almost decide to not watch the remaining episodes.. however, the suspense is started from 3rd episode and I could not stop to watch it after that haha..
Really love how the actor and actress play their character and role..

This drama is listed below so much that I would miss it totally. This should have been placed with two weeks where u get hooked with the drama till the end. So much of suspense, twists, emotions. Totally loved it and lead actor. This is the first time I am watching him and he did his role perfectly. wow such a pity he had done only few dramas. Would like to see more of his works. Awesome drama. Glad I watched it.

Such a great drama with a great plot and very addicting. Few bits of teary moments

This drama is so good. The story is unique; they should have made this drama longer.

Loved it. Seen it thrice already! it's a good watch. good twists. Great acting by the lad actor. Amazing action. Even the bad guys look dapper!

This show is an intensity pill and it’s just so good that you can’t stop watching. Highly recommend especially the action scenes mixed with the OST. Props to all the actors and actresses. They did an amazing job.

26 Partners for Justice

Just loved this drama. Mostly in other dramas and movies they don't follow the normal procedure of investigating a crime but in this they properly show the procedure not only that in most dramas they only show from the detective/prosecutor view but in this drama they show the scientific view of science. Also the cast, they're so good. Everything about this drama is just so proper and is done in a scientific way not like the fantasy kind of, it also has many humorous scenes to not make it boring. They ended the last episode on a cliff hanger and the 2nd season is going to come soon and I'm eagerly waiting for it. If you're fed up of the normal fantasy kind of dramas and want a reality based mystery action thriller then this is a must watch.

Really mean a lot.. the chemistry and teamwork of the medical,prosecutors,cops really good to show

Love this drama! This is definitely a must watch!

This drama so interesting. You all should watch this. I love Lee Yi Kyung as detective in this drama

27 The Girl Who Sees Smells

I love this drama. VERY RECOMMENDED TO WATCH! It's a good drama with a good flow, the mystery that keeps you biting your nails, and it also has nice comedic reliefs (which I really really love). My mom and sister also loves the drama so much. You'll end up loving a lot of characters in this drama. The main leads, the supporting police roles, even the villain who commits such brutal murders.

This drama is very recommended..its really fun to watch..when people asked me what is the best korean drama to watch..then I would suggest this drama..really good drama!

Romance, Suspense, Fantasy Drama~
This Drama series adapted from the webtoon by Seo so-kyung a/k/a Man Chwi.

This drama was really well written. no rush and lost moments; a very smooth and steady process all towards the end. love the comedy reliefs too!
Despite low ratings, the drama managed to top the Contents Power Index (CPI) rankings for the most influential dramas.

31 You're All Surrounded

This show was amazing. It had a team of rookie detectives with one hot-headed team leader. Characterization=amazing. Plot=great. Romance=great.

This k drama was totally amazing. The cast was on point and all the cast suited this k drama so much. It's about a boy whose mother had been murdered when he was young and he becomes a police officer and a girl who also becomes a police officer. I dunno if it's just me but I love action k dramas and especially police officing so this was the perfect one for me. If you haven't already watched this k drama then I don't know where you've been but you really need to watch this k drama as soon as possible. I just finished watching it and I miss it so much. So I highly recommend this k drama to anyone who hasn't watched this k drama yet. It was a daebak k drama. Sarangheyo to this k drama.

32 Missing Noir M

! It is the BEST police/mystery drama I have ever seen! The man who did this must truly be a GENIUS! Such a complicated and intelligent plot...

Loved this! Cried a river in the last ep!

I can't believe that this drama has only 10 episodes. This drama kept me thinking over all the episodes. I can't even sleep thinking a single case. It kept my brain working while watching. This is totally daebak! The writer is a total genius!

This was a great great series! Wow

The whole mood of this drama is very good. There are sprinkles of comedy and barely there romance. I like when a crime drama knows what it is and doesn't focus on unnecessary subplots.

nice drama

Loved it. It keeps you in suspense, revealing one twist after another. It kept me on the edge of my seat (my bed) and wanting more. If you love murder/mysteries with a whole lot of thriller, then this is perfect for you.

Must watch. One of the best

This is a must to watch kdrama it is about a girl who can see the shadow of death and a grim reaper who is looking for his partner who run away from the underworld

36 Come and Hug Me

This drama got me watching it twice right after the first time! the feels were so deep and it makes you think so does the murderer's family deserve so much hate? What is it like to be in a murderer's family? I cried the entire time and my heart literally explodes every single episodes! It got me crying from the start to the end

The actors are so good I get the feels every single episode I watch there is really nothing better

Just finished this show yesterday. it kept me on the edge of my seat. heo joon ho was absolutely AMAZING as the serial killer (this isn't a spoiler). I would absolutely recommend

37 Who Are You 2013

I have yet to complete it but so far, it's chilling me up. Ghosts never scared me, but when you add detectives who actually see ghosts to a lot of past strings, it will chill you. - rin2787

It depicts the true meaning of school, family, friends and education. It's like I'm looking back, back to my high school days.

Amazing cast, acting and plot! could watch this drama over and over again.

Couldn't finish this...i really tried but just couldn't. I quit after 10 episodes. I might one day go back and watch the last 6 ep...maybe...

38 Save Me

I decided to stop after 4 episodes because the whole religious cult thing was totally getting on my nerves. But when I tried to continue, I started to view it from different point and this drama really touches me to the bottom of my heart. I've learnt so much about sacrifice in true friendship. Most countries do have the freedom of religion, but how they brought up Sang Mi's act was priceless. This drama will sure have a place in my heart. A lot of directors don't bring up religion in their story because of conspiracy, but this story deserves oscar let me tell you. The religion in this story is fictional, it's non-existent so anyone can watch this drama regardless which religion you are. I promise you won't be disappointed just like how I didn't. Needless to say, I curse damn much because of the tense during these whole 16 episodes. So good luck!

Seo ye ji best korean drama..she shows to us her acting talent very favorite korean drama is save me.second is voice drama

39 Triangle

This is a must watch korean drama! I just finished watching Empress Ki back then, then I followed Ji Chang Wook and Baek Jin Hee here! It's a superb that I recommend it to those who love action dramas and those who are just staring to love action dramas!

"The plot was very good. The acting skills, the action scenes. It's a wholesome! "

"What you are looking for a drama is here! "

The last episode was everythinggg. peefect

Really love the plot of the story

This show is honestly underrated, everyone should watch it! it's not only about negotiation, it also talks about how the rich are more privileged than the poor, the OST is sung by kim bohyung "our story", ITS REALLY GOOD.

41 Remember

This is honestly one of the best and most underrated dramas out there.

One of the most fascinating dramas ever..highly recommend this... one of the best dramas that reveal the hidden truth behind the money of the powerful people..

42 Mask

Really good

43 Time Between Dog and Wolf

One of the most interesting dramas with many twists and changes. Even after 10 years I always think about time of dog and wolf (when the sky darkens and you can not clearly see and distinguish between dogs and wolves). One should watch the drama to understand that you never know who is a friend and who is not.

44 Children of a Lesser God

This is movie is amazing, the power the lady holds is wow

I have no words for this drama bcs this is the only drama (if not one of) that makes me sit still since ep 1. that's how good this drama is. Ocn never fails to make a good drama esp for this type.
If u like Voice Tunnel & Signal u would love this.

45 Circle

Thrillest of the thrillers. Too good to rate


46 Swallow the Sun
47 My Beautiful Bride

Since I only started watching this Kdrama because it looked good I can't exactly explain the plot based on rating and reviews but from my personal opinion so far it is making me speechless. I'm not exactly sure what genres it is under but it includes suspense, thrill, crime, romance and melodrama. If you enjoy Kdramas with gangers, corrupt organizations and loan sharks then this is perfect. It includes a tragic love story which sets off a war. Young Hee and Cha Do Hyun become close in high school but because of an incident including both students, young Hee leaves and cha do hyun transfers volenteeraly. Years after high school they meet again, Young Hee works at a Hostesss' bar and cha the young is about to start military training. One day young Hee get approached by a detective and asks her to be an informant so she excepts because she wishes to live happily with cha do hyun. After she accepts, the head of the organization gets arrested and young Hee goes to live with cha do hyun. 2 ...more


This is really good

49 Sketch

Sketch is one of the new dramas in 2018. I highly reccomend it. it's about a girl who sketch peoples death and the death will happen within 3 days. her brother can see the future. and their detective team will do their best to not let the deaths happen. it's a drama with a lot og twist and it will give you goosebumps - hope you enjoy the Drama Sketch

50 School 2013

I lied to myself when my head said "No excess Lee Jong-Suk, no excess bias." I couldn't stop myself and I couldn't leave this out. Even though this entire drama is based on high school, it's not giddy,and there is almost 0%romance, minus the very negligible vibes. So what exactly is this high school drama about? High school darkness. It consists the problems that revolve around high schools-- bullying, violence, preparatory pressure and whatnot. Why wouldn't anyone watch this? I don't know. It gave me enough goosebumps to keep cool in summer. - rin2787
