I planned not to watch it, but Lee Soo Hyuk is acting there, so I'll probably watch a few episodes (just kidding, he's one of my most favourite actors, I'll definitely watch it :D).
I have just watched the first episode, and I must say it's pretty interesting. The plot is really interesting, although I didn't like few characters. Anyways - if this drama will continue in interesting way, just like in the first episode, then I think I would definitely watch it to the end :)
