A truly amazing drama that constantly left me wondering what's going to happen once. As much as I try to predict the next episodes, It always surprised me with their unpredictability and mysteriousness. Every character has their unique characterization especially Gong Hye Won, Jamie Layton, & Lee Ji Wook but everyone is outsmarted by the protagonist mostly, Do Jung Woo, and Moon Jae Woong who is the anti-protagonist for the most part of the story until the true villain surfaces. Jung Woo always is shown to be very calculative regarding his plan and is prepared with a counter-measure if anything goes wrong.

I really love it when a story has many smart/strong characters and potential ones while many other dramas intend to have a weak and gullible character especially the FL. Even though everyone gets fool by Do Jung Woo, it's not entirely their fault because he is a mastermind and everyone he fooled has had some form of a deep relationship with him.

Gong Hye Won is a smart and hot-tempered Officer as described in the synopsis but there is more to her character. She is aslo shown to have a feeling for Do Jung Woo who happens to be using her along with the entire group. Gong Hye Won finds out about it but didn't want to believe it until a certain event. But the intention of Do Jung Woo is not that clear as well because even though he seems to be using his team and many others to take down the foundation that started the whole child experimentation. He does seem to genuinely care for his team especially Hye Won and Jamie because the show tries to emphasize that there could be other possible reasons for his recruitments of them other than their relationship to the foundation.

Although the plot is not romance-driven, you can actually feel the intense feeling Do Jung Woo and Gong Hye Won have for one another every time they are face to face or shown to be thinking of each other. The ending also tries to hint it a little bit. I have to say: this drama was simply impressive from the beginning to the end.
