This is one crazy good drama and it reminds me of Fight Club. I always thought Lee Dong Wook's chosen dramas lacked good plot lines but with this one he just nailed it. He tried to add a little flair with his dialogue delivery and acting in this drama which actually seems to be working for me, not to mention how handsome he looks. The contrasting, sarcastic and hilarious dialogue delivery and tonality reminded me of how much I liked the same about Kim Min Jae in 'Dali and the Cocky Prince'. The contrast of the split personalities are really well shown by casting Wi Ha Joon and of course, he is a terrific actor himself so there is a really good tug of war chemistry between the. two personalities which was absolutely needed for this drama.

Personally, I'd also add a romance tag here, coz well that kiss scene right there was too good for this not to be considered a romance. For me in a suspense drama no matter how serious it is, i require there to be some romance in there for me to be satisfied and I think that thirst was quenched. :P

Just finished episode 8 now and I can tell the upcoming episodes will be entering into the dark side with some heart wrenching stories to the boot....perfect don't you think!

All in all, you'll miss out on a really really good plot and drama if for some strange reason, you decide not to watch this one. I am eagerly waiting for the next episodes.
