To start off with - I don't know why this drama is categorized as a Romance drama on DramaWiki - there's very little to none in this drama. That aside, the drama was good without it. From the beginning I wasn't sure how I was going to like this drama, it's not that the story was boring, but it is a little slow in the beginning. What kept me going farther on is the mystery. This drama was more of a mystery/suspense/drama. It had me wondering what was going to happen next. Almost all of the characters gave me mixed feelings, at times I wasn't sure how I should feel about them. Especially Kim In Sook. As a main lead she's hard to understand and it's hard to like her because of that. Each episode made me wonder who exactly she was, what had happened to her to make her the person she became. Ji Hoon's character was one of the few characters I found myself liking from the beginning.

The acting was great! It was really good! I started watching this drama because Ji Sung is one of the main actors (Ji Hoon). After seeing him act in Protect The Boss I wanted to try another one of his dramas. To see him go from a more comedic role to something serious just proves he's a great actor. If you're a fan of his, this drama won't disappoint you when it comes to him. The main girl, Yum Jung Ah, did a really good job with her character. The other actors were great, as well.

The music fit the drama. There were a few songs, none of which stood out to me though. The instrumental part was good, the ending of each episode when the song plays made it out to be even more intense - and to see what happens next.

My rewatch value is low because although I found this to be a good drama, it's not something that became a favorite or something I'd want to rewatch more than once.

Overall - I think this drama is worth watching. If you're in the mood for something at a different pace aside from romantic comedies and such, this is a good drama to watch.
