    Wow...nicely executed, this drama really keeps you on the edge of your seat and consistently engages your emotions in a such a way that will literally have your blood start boiling and eye balls glued to the screen as you anxiously wait to see what will happen next. Furthermore, the plot of this drama, while simple in design is built with so many individuals intertwine into one big storyline, one can't help but feel over-time the complexities that arises out of such a simple course of action...

    Going further, what makes this drama so engaging is that it puts the human emotions and experience of betrayal, vengeance, love, family, friendship, and money into a universal context that possibly anyone can relate to. First

    This could have easily become my favorite K-drama of all time if not for the last 3 episodes. THEY KILLED IT! Murdered, shredded, destroyed everything this drama had going for it.

    From the first episode I was sucked in and curious as to what was going on. I did not understand much, I did not know what was happening or where it was going, but I was somehow captivated and hypnotized and could not stop watching. I mean, KIM NAM GIL - I had never seen him before in my life but I was instantly enthralled by him. It was love at first sight. Until this day I do not know what it is about him that I like so much. In this drama his character

    Honestly I kind of got a little disinterested when I found out she didn't end up with Tae Sung XD
  • BlueBeauty Feb 10, 2014
    Is it just me or I am the only one rooting for Hong Tae Sung?
    • RainieDee Mar 21, 2014
      So I'm not the only one!I don't know why but I always fall for the one who suffer or had a sad love story if we can say so.(just like Tae Sung)
    • BlueBeauty Mar 21, 2014
      Have you seen Who are You? Yeah, try watching that! I think I'm only that way because of Kim Jae Wook! XD
    • RainieDee Mar 22, 2014
      I wanted to but when I heard that he is not the main guy I stoped.I don't like when the guy I like isn't the lead character...(You know...I barely watched I miss you)
    • BlueBeauty 28 days ago
      I haven't seen that yet is it worth it?
    • RainieDee 28 days ago
      Yeah it's very good.And if you are like me then you will like it too,because in my opinion Tae Sung is like Kang Hyun Jung(well with little diferences...)

    This drama surprised me as I wasn't expecting it to be so good. I was mostly anticipating a typical melodrama with a lot of makjang and self beating but it wasn't the case at all. In this story the revenge theme was extremely well thought out, refined and was focused on its psychological aspects. The twist of the story in the last few episodes was what turned the drama in a real melodrama and the ending represented its peak. I thought the acting of all the main leads was brilliant and in particular Kim Nam Gil was quite outstanding (much better than in Shark). This drama deserves to be seen as it is intriguing.

    for the record KNG had to leave for his military duty so they had to cut the drama short..kinda explains the ending.

    I'm revenge dramas fan and was told this is one of the best... I kept postponing it ever since it came out I don't why though I just wasn't interested but finally decided to watch. Though I already knew this drama will go down to hill at some point cus Kim Nam Gil had to leave for the military so they wrapped it up real fast... However I was still hoping that the story would be worth it regardless of the damage but sadly it's not the case... to me this drama went down to hill after the 5th ep, every ep then was long and boring... The only thing I liked in this drama and made me stick to it till the end is KIM NAM GIL.

    This is my first drama for KNG and he did an amazing job, I'm really mesmerized by him !! his expressions, voice, movement and gaze EVERYTHING !! he's the reason I'm going to say watch this drama... having him here means it's not a waste of time HE is worth it !!

    • Marooya Jun 28, 2013
      I'm glad I postponed it !! at least now I can see his upcoming dramas rather than falling for him and waiting 2 years for his comeback... haha lucky me I can start his new drama Shark :P

    Oh, why there's "Action" in the genres? This drama has nothing to do with action, there's no drop of action in it so it's better to delete that genre.

    • Raincat Jun 12, 2013
      I agree. Genres what describe this drama better are:
      *Melodrama: The term melodrama refers to a dramatic work that exaggerates plot and characters in order to appeal to the emotions.
      *Suspense is a feeling of pleasurable fascination and excitement mixed with apprehension, tension, and anxiety developed from an unpredictable, mysterious, and rousing source of entertainment.
      Revenge dramas are all suspence and dramas what from ep to ep make your emotions go up and down are melodramas.

  • CheerfulSoul May 23, 2013
    This drama had potential to become a great revenge drama but it went downhill at some point which ruined everything.

    I still loved Kim Nam Gil in this, he was flawless; his expressions, actions, words and even his smirks, it makes you go obsessed over him.
    The kind of male lead that I would like to see in every revenge drama out there.
