I had watched IRIS so I had high expectations of this drama. This was a bit slow in parts and frustrating to watch the characters who were suppose to be smart act so incompetent. I did not like the character of the male lead Jung Woo, who was like a love sick dog! Most annoying was the seemingly impunitive way in which Hye In was treated given the seriousness of her crime. Didn't like this drama and the ending sucked most of all! Wouldn't recommend unless you really have nothing else to watch.
