Going to be brutally honest and say this is the worst K drama ive ever watched. Watching the teaser it seems like the perfect thrilling drama, it is quite the opposite. The writers seemed like they wanted to get so much twists snd shocks in it that the show was just an utter mess in the end. Im not sure why I continued watching perhaps because with all the useless twists I wanted to see how the end would pan out. The end was terrible. The leads are both unlikeable, although I did feel sympathy for the female lead at times. It was overall pointless and went nowhere.
