Very convoluted with all it's twist and turns, almost in a mind numbing way. Some aspects of the show have a very familiar feels.

A dominant ML and 2nd ML. An amnesiac FL as the heroine. Beautiful traditional/period costumes, good looking actors, artistic fight scenes, and a great love that defies all.

The length of the show allows each character development to take place. They started as young person's full of angst and uncertainty. Then they've been through a lot, gain alliances and some enemies too. They've love and lost and love again. Anyway, it has a happy ending so all is good.
