Honestly this drama was great, just plain fantastic. I watched this because I heard Jung Kyung Ho was in it, but stayed because after the first episode it just made me want to watch it some more. I didn't think I'd be able to finish all 20 episodes and even thought about dropping it. But each episode intrigued me and forced me to keep on watching, it's the kind of drama that makes you hooked just like that. The plot is really great and the characters are even better. The one thing that's really unique about this drama, is that it keeps you guessing. From the first episode all the way to the last, you never know what's going to happen next. You don't know who the good guy is or who the bad guy is. You don't know if you're rooting for the wrong team or the right one. And it has everything a thriller needs; from violence to drugs to gorgeous guys in suits (and gorgeous guys out of suits kekeke..). It's a drama worth watching and if you haven't watched it yet, what are you waiting for?!
