The performances of all the actors from the first episode to the last episode were excellent and they reflected the tension, excitement and cinematography wonderfully on the screen. My favorite character from the Kdrama was Koo Dae Hong. The Kdrama's song was also very good. I think this Kdrama could have continued for a few more episodes. I think they tried to end it quickly. I think it could have been 10/10, like "Memoir of a murderer".
