I thought this was an amazing drama. I didn't watch any in a while but once i watched this, i was addicted. I wanted to watch more and i couldn't wait until next week! Oh those long waiting periods!!!! But! Its finally over and it was amazing. Ji Sung had to play several roles since he has D.I.D. And his roles varied so after watching this, you learn he is way too amazing of an actor. The female lead was pretty good too but the attention was on Ji Sung.
I saved all the episodes and ive already watched this 3 times. The story was amazing, and again, the roles the actor's played was perfect (and thats an understatement).
MUST WATCH DRAMA!!!
