I loved it! This is the type of drama, that you won't regret watching. I became a fan of Lee Jong Suk in this drama. He is a very good actor, when he cries, it is heartbreaking. Even Yoon Sang Hyun, Lee Bo Young and Lee Da Hee were really good here. The story will keep you in suspense and just keep watching. So beware, you might have to stay up (based on my experience).
