Excellent script, unique characterization, excellent actors, no extra scenes, attractive in its own genre in such a way that you are running to the end of the story to see what happens.
I can't tell you how good it is, lovers of action, thriller and mystery genres, hurry up because this series is for you.
Lee Dong Wook was also very good here
I fell in love with the relationship between Ki and Soyol.?
I say again, check it in its own genre, for example, if you want romance, this series is not for you.
Indeed, if you are sad after watching a TV series and are looking for something to make you feel better, this is a very good choice
