    Daebak! I’am excited 😍 na na naaa ~

  6. 6 : Reem. mon Says:

    Nice poster 😍 excited to watch it

  7. 7 : driving directions Says:

    The film looks promising. I will watch it, I also like the kind of film about the detective.

  8. 8 : sanjinyeon Says:

    Another OCN thrilling Kdrama, after Tunnel my expectation for Duel is quite high. I’ll keep my eyes on this start next week.

  9. 9 : Jacksully Says:

    I miss Tunnel; now I’m waiting for Duel then. I hope this story is great like Tunnel.

  10. 10 : Duel, o novo drama de ação e suspense da emissora OCN Says:

    […] Fonte: KorenDrama […]

  11. 11 : Hannah Says:

    After Voice and Tunnel, I have a high expectation on this drama. Ep 1 was a lil bit boring, but episode 2 gets better! I’m gonna give it a try to next few episodes because OCN thriller drama never fails to reach my expectation in a drama. The preview of episode 3 also looks interesting!

    Btw, I was so glad that Yang Se Jong got the psychotic role when I first read the news. He’s a newbie, but he’s a very talented actor. I love him both in RDTK and Saimdang LD.

  12. 12 : MaxT Says:

    It’s not better than Voice or Tunnel, but it’s not boring. It’s worth watching.

    I give 7/10.

  13. 13 : pepit00 Says:


    She in this drama too play one of the detective

  14. 14 : Hannah Says:

    Anyone knows what song they’re playing in this drama towards the end of ep 3 when the detective’s trying to wake the small girl up?

  15. 15 : Hannah Says:

    I’ve watched this drama until ep 5. I think JJY’s acting is a lil bit overreacting and it makes me somehow lost a lil bit of interest to continue watching this. Plus, the prosecutor Choi’s character is so annoying that I find both of their actings/characters are kinda irrelevant.

  16. 16 : Coolbeans Says:

    Got boring very quickly when it showed promise in episode 1. The ratings are accurate. The prosecutor is too inhumane. Her clown like makeup and expressions are creepy. You don’t feel connected to any of the characters even the policeman whose daughter was kidnapped. Not worth watching.

  17. 17 : Jukbang Says:

    Not good at all . The storyline so slow, boring & drag too much. For this genre type of drama twisted & confusing plot is normal but it failed miserably in this drama. The thrill factor is non exist & what is the 2 reporter is all about ? DUH.

  18. 18 : suppledexplorer Says:

    Cant let go of this drama..waiting for the next episode!!!

  19. 19 : Hannah Says:

    This drama is getting better! I love both Sung Hoon and Sung Joon.

  20. 20 : suppledexplorer Says:

    Kudos for this drama!!!!

  21. 21 : ㄴㅇㅅㅌ Says:

    1st 2 eps were slow but it’s a unique and exciting drama. Not to mention Yang Se Jong is soooo cute and a really talented rookie actor! It must have been really difficult to portray 2 roles but he managed to pull it off! Hope Sung Joon & Sung Hoon survives till the end!

  22. 22 : Azziris Says:

    Yang sejong very handsome. I like this drama, but it better if sung joon died too.

  23. 23 : Asa yu Says:

    Worth watching…yang se jong is a very good actor…hope to see more of him in the future

  24. 24 : winnie Says:

    It was promising, then a little dragging, then good. The reporters are both not lively actors, so a little lacking. YSJ is awesome. But I didn’t understand at the end how will Sung Joon treat his aging? Or is he waiting patiently to die. Overall 8/10.

  25. 25 : Winnie Says:


    The song is called 악몽 or nightmare. If you type in you tube “Duel OST part 1” you’ll find it.

  26. 26 : WONDER Says:

    nice action and novel . great drama at all.

  27. 27 : sue Says:

    watch up to episode 4, the CJH the bastard. the drama getting better.

  28. 28 : Sabi Says:

    yang sejong really a good rookie actor. in this drama he played 3 roles (include as the doctor) and each character really strong. i bet he gonna be a promising actor in the future. and about the storyline, it’s slow and confusing at first, but after 7th episode, it’s more interesting.

  29. 29 : dramanice Says:

    nice to watch

  30. 30 : Lambingan Says:

    Contessa pinoy drama online live

  31. 31 : Kay Says:

    Duel is an amazing drama! So intense with an excellent sci-fi story. Yang Se Jong was truly amazing in dual roles here. I was blown away by his performance. Highly recommend this drama!
