An amazing story, Just lost its way. (i mean it became bad).
Negative character can be shown more amazing, it was shown amazing in the beginning and showily dropping it off and I feel because of too much love it lost its original beauty.

Worth to watch, I say NO but few scene you can.

Cinematography is good
editing is not bad,
flow of drama from episode to episode not good (very few episodes you will like it) and in few episodes they will confuse you
People who like Suspense Drama’s would love this drama but they will get disappointment by the mid of drama.

More then Lee Min Ho, Woo Do-Hwan acting is amazing.
