Intriguing and good suspense.

OMG... I never thought I'd one day like a non romcom drama. This is the one of the best SERIES I ever watched. The suits are very realistic and beautiful. I didn't like True Detective or the American version of Infernal Affairs or most Crime Thriller. The ending kinda crumbles a bit but it's still good. The OST is just OK. The main character is very psychopathic. Their were some few minor bad plots and it seems that from time to time the directors changed his mind on the storyline.

The story is very complex. This is definitely a good watch.
