    I can’t wait for this drama
    Woo Do Hwan is doing a great job in Save me

  2. 2 : Mardonna Says:

    I pass on this. Sounds boring and the choice of actresses moved me.

  3. 3 : JustRozy Says:

    Sounds very promising–looking forward to this! (Full disclosure, I would happily watch Yoo Ji Tae read the phone book). But looking forward to this FOR REAL!

  4. 4 : Nonuts Says:

    First 2 eps were good.

  5. 5 : Syub Says:

    First, i read the synopsis and its sound boring. But. after watch 2 episode. WOW! Drama which looks like movie!

  6. 6 : Sinopsis Mad Dog Says:

    I can’t wait for this drama

  7. 7 : sanjinyeon Says:

    from “Save Me” to “Mad Dog” tiger look eyes that will melt your heart “Woo Do Hwan”.

  8. 8 : eommageom Says:

    i love this drama.Mad Dog,,,figthing 🙂

  9. 9 : Tina Says:

    I liked acting Yoo Ji Tae in Healer very much. And now he is working with Woo Do Hwan. They are good actors!
    Also I liked love story between Kim Min Joon-shi and Jang Na Ri-shi👨💕👧!

  10. 10 : OK OK OK Says:

    Woo Do Hwan ssi somehow looks like RAIN – in my opinion. ha ha 😛

  11. 11 : nomnomnom Says:

    at first, i didn’t really care that much about the drama from reading the synopsis. then when i was in youtube, i happen to watch mad dog ost and it kind of motivated me to watch the drama >u< and its a good thing i did because this drama is like a masterpiece! the pace is not too slow not too fast, everything falls into its place. it feels like i watched an hour of episode in just five minutes! also i really love ryu hwayoung and woo do-hwan chemistry♥♥♥

  12. 12 : Kaddictss Says:

    Woaa guys you have ti watch this drama, its very nicely done, all characters are not boring, I live for Jang Hari and Kim Min Joon moments …. but dont expect to much on them…this is not a love themed drama… all of the viewers cherish their moments…it might me small but its very heart warming because both of them are very tough…this drama keeps getting better every episode…its not your usual drama, it also has a family touch, action scenes, relevant events(INSURANCE FRAUDS) and many more!!! JUST WATCH IT ALREADY!!!

  13. 13 : OK OK OK Says:

    I enjoy watching this drama about insurance payout scam etc. Quite exciting 😛

  14. 14 : CoolBeans Says:

    I LOVE IT😍
    This drama is much much better than the ratings. There are cliff hangers at the end of every episode. The characters are smart, believable and fun to watch. The storyline is relevant to recent incidents and tragedies that pull people together and expose corruption, greed in large organizations. Just of touch of romance in this, but, the focus is action, intrigue, corruption and family.

    This has one of the most heart wrenching sad scenes I have ever seen in an Asian drama. I cried like a child watching You Ji Tae poor his heart into the sad scenes in the early episodes. Definitely worth watching.

  15. 15 : OK OK OK Says:

    Love this drama. Just finished episode 14 – soooooo exciting. Love the singer’s voice and the songs too ….. 🙂

  16. 16 : OK OK OK Says:

    I vote for this drama too 😛

  19. 19 : sanjinyeon Says:

  20. 20 : OK OK OK Says:

  21. 21 : DeeAn Says:

    @kaddictss. Your opinions discribe mine. Could not agree more
    On every episode I enjoy and I keep waiting kim min joon-jang ha ri moments I thought they both do platonic love before, but so happy at the end of episode they already have romance relationship huhuhu ^^


  22. 22 : heynie Says:
