This drama is the COMPLETE PACKAGE. The cast was excellent. The story beyond amazing. The music, just perfect. From ep 1 you will be hooked by the storyline and the characters. You'll keep on guessing if Hyun is really bad or good, whether his relationship with his wife and family is all a facade. It will also make you scratch your head trying to guess who the real accomplice is, I know I did. Just when I thought I had it all figured out, then I find out I was wrong. There was something new in every episode that you will never lose interest and the depth of emotions that the leads displayed was so remarkable. Lee Joon Gi and Moon Chae Won really outdid themselves. Lee Joon Gi can display so many different emotions on his face in a matter of seconds, what a pro. This is really such a turnaround from his last drama, Lawless lawyer which I hated. This drama for me is the BEST this year, period. I can't stop raving about it and it definitely is in my top 3 of my all time fave dramas. What a satisfying watch and my expectations had been exceeded.
