As a reader of the novel, I'm going to say this might be the closest novel to drama adaptation ever. It kept almost all of the parts in the novel and added storylines to the main and side characters the original novel was pretty quick and simple but the drama added more depth to it. I'm kind of disappointed that because of budget and time the drama had to end on such a 'cliffhanger-y' note but the extra episode at the end of everything(ep37) gave us a good simple explanation of things as long as you look closer into the scenes and details. Watch it, the costumes, effects, music(omg the music in this drama was ALMOST just as good as The Untamed) I recommend going online to find the ost of Word Of Honor after or before watching it because the songs were beautiful. Stop reading reviews and just go watch it gogogo!
