This drama was amazing! I loved the plot and the thriller part but if it, but there were times when the plot did confuse me but other than that... this drama is really good. I totally recommend this thriller/mystery drama to anyone who wants to expand more in this area. I love the actors especially Jang Hyuk who portrayed a good character. His acting was splendid and so were the other characters such as Lee Ha Na (love her), Lee Jae Wook, Baek Sung Hyun, etc. This drama, in my opinion, is a drama worth to watch especially the plot and the message of this drama to the viewers.
