(This is my first review) At first I thought this drama was going to create a Korean version of Sherlock Holmes (has that been done?) but the direction switches and a much deeper and tragic plot emerges. The plot is fantastic and I think it is the strongest aspect for this drama. Although there are mostly dark themes evoked in this drama, I appreciated the light moments that are nicely timed and blended with it. I love the fact that no over-blown romance happened between Cha Ji An (Jang Na Ra) and Lee Hyun (Seo In Guk). In the end, you understand that they care for each other and the pace of their relationship is realistic given Hyun's personalty. I first saw Jang Na Ra in Baby-Faced Beauty so when I realized her role in this was a police officer, I had my doubts. She is so cute and petite. However, her acting was brilliant to the extent that all doubts were tossed aside. This is the first drama I've seen with Seo In Guk and he is amazing in this. He never came out of character except when it seemed fit (during the last few episodes). Personally, I think because of his character's cold and unfriendly behavior 99% of the time, the moments when he cried were profound and heart-breaking. You remember that he is still human. Choi Won Young plays the "bad guy", Lee Jun Ho, excellently. I think the beauty of his character is that the crime he committed is controversial and requires you to really think about what he has done. Which makes me appreciate Cha Ji An's inability to be swayed by Lee Jun Ho's view of himself not doing anything wrong. Lastly, I feel the ending hinted on a season 2? That would be awesome. The sound-track is absolutely fitting and lovely. The moments when Hyun and Jung Seo Ho (Park Bo Gum) spend together as brothers are so adorable. What I didn't like about this drama (minor things): The poster. They make Cha Ji An look like a seductive vixen after Hyun's money. It is totally out of her character! Cha Ji An is smart, strong, messy, and clumsy as hell! Make her look that way! I wish they had spent a little more time developing the closeness of the two cops, Eun Bok and Min Seung Joo. Yes, you get the idea that they are a tight knit team but when Eun Bok "gets in trouble", Min Seung Joo tosses out that he is like a "brother" to him. I felt that that was just thrown in there. I never really felt that those two characters where THAT close. I would have believe it more if he had called Eun Bok a best friend. The team's outfits. The first time I saw the team I thought they were drop-outs from fashion school. These characters are POLICE OFFICERS and only once was I ever convinced they were dressed for the part. HOW CAN YOU RUN IN THOSE SHOES? Overall, I recommend this drama. P.S. It is really hard to not post spoilers but I respect that.
