This is one of the very few Korean dramas I've watched. I usually don't watch Korean dramas if the story doesn't get me really hooked. After watching the first episode of this drama I didn't really expect much, but the reviews were good so I kept watching and at the end it went beyond my expectation. I didn't think I'd like this story this much.

The story, actions scenes, romance, relationship between people and the suspense, everything about this drama were perfect. The music was really good. The cast did a very good job, the actors acted very realistically, one thing I really love about this drama is there are not any unnecessary drama or misunderstandings, they sorted out things fast, that way they could focus on the main story well.

Overall, this is a totally recommended drama, watch it!! It won't disappoint you.
