Okay let's get to the point this is the best kdrama I have ever watched no romance, no dragging of story, no boring episodes and every episode was thriller which was the best part. The story line is OH MY GOD, the plot is like too good to handle, everything in this drama is UNBEATABLE and in my opinion this drama is the best drama I have ever seen in my whole life and I will never take back my words that "NO KDRAMA IS BETTER THAN THIS".
