The show was the best historical kdrama I have ever seen so far. The story was so good and all of the plot twists would hacked your brain. The characters development, especially Bang Won and Moo Huyn was so deep and nature that even if they have become evil I still root for them. The bromance in this series is freaking gold, especially in the last 20 episode. And not only bromance, romance and other relationships like friendship or fathership are also well written. Please watch it till the end and you will know what is a good quality historical drama.
