The first thing I notice was the OST kinda mission impossibleish!! for the lack of a better word, not bad actually fits the scenes.. Hang Geun Suk did a decent job in portraying both characters of Do Chan and Joon Soo, from his posture, body language and his facial expressions. I was annoyed with the female lead. The first few episodes showed her to have brash, condescending, and irrational ( for a prosecutor at that). Her and her chief cannot keep a poker face and their demeanor are dead give away regarding the fake Joon Soo. I cannot believe that she had the nerve to ask if Do Chan was jealous of Joon Soo. I was grateful that Do Chan set her straight when he told her no more disrespect and no more name calling (CON ARTIST). Not quite sure if I can endure her till the end. I've seen KDramas tend to over exaggerate the main characters in the first few episodes for character development. I'm not rooting for a happy romantic ending between Hara and/or Joon Soo, Do Chan.
