OMG...OMG...this drama is one of the best action drama I've seen by far.Very, very good drama to me is when I would loose nights of sleep because I cannot stop from watching. I can't stop thinking about it when it finished. This is one of that drama. My nephew been telling to watch it and I'm so glad that I did but regret it that I should have it sooner. It made me Appreciate Korean dramas even more.
