This drama is a masterpiece. Definitely the best drama aired 2012. Haven't seen drama like this before. It is very unique and great. Story: Story is very different and addicting. It made me laugh and cry, feel sad and happy and even nervous, confused and annoyed at some point. I didn't get bored even once. There is lot of things going on all the time and I personally like it very much because it gives lots of things to think about continually. Cast/acting: Characters are very well created and acted. Cast is just brilliant. Big plus to main characters that are smart and have big personalities. Music: I really loved the music in this drama. Perfect match! Rewatch value: I finished this about half an hour ago and I'm dying to watch it again soon.
