I was a nice drama. But the plot wasn't really fresh and a bit predictable. This story is common in crime thriller dramas in SK (I cannot tell more because it's a major spoiler). And I was bored a biiiit. The second thing that was a bit unsettling is Ha Jun Won's character. I didn't understood his motives. Why he did alll these? Why he is so obssesed with this case? They never explained it. For the other part, Lee Dong Sik or Park Jung Je's characters was really well written with great depth.

The good thing, the really amazing acting from the whole cast. Everyone was really great, especially Shin Ha Kyun (he gave me the chills sometimes. )
