A real-life legend who created a martial arts guild in Joseon Dynasty. His group that defends the King is fighting against a mysterious organization of assassins who plot to kill the King...

We got all wonderful friendships, bromance, brotherhood and painful rivalry. A lot of sword fights between enemies and comrades who has just silently sitting next to each other. The acting were so moving and beautiful! All the kid actors enchanted me in less than 4 episodes and I wanted to see their journeys. Also their teen actors, all of them portrayed their characters very well and distinct. It has a stunning choreography and epic OST. The politics are quite confusing and complicated, but I ignored it and focused on the characters and their bonds, it works!

Despite my strong praises, there are shortcomings which actually bothered me throughout, plot is quite messy with a lot of unrealistic twists, with long drags in the middle. (SPOILER!) At a point I lost interest when there’s a twist that really diminish the relevance of the leads, and this infuriated me, why they end up to be so unimportant to the story? So I wasn’t enjoying watching the last quarter episodes and finish it just for the goodwill for the characters, as I really loved them in the beginning of the drama.
