This is one of the best drama I've watched and it's going straight on my top 10 favourites out of the 200 I've watched/skimmed through/dropped since I fell into CDramaland 2,5 years ago.

There's everything I can ask for this type of drama: solid acting from the whole cast, good character writing, good cinematography and music.
There's humour, emotional moments, healthy relationships, interesting female characters, beautiful friendships/bromance/female solidarity, welcomed twists on overused clichés and beautiful fight scenes.

I was watching it for LYN and I'm not disappointed at all, he's good at picking his acting projects and is really good in this, as is the whole cast. (even the "weaker" actings are so much better than in most of the CDrama I've watched.)
