Story:
(+) Though it is 70 episodes it didn't drag. Sure, there were some slow parts but almost all dramas have slow/boring moments. I'm glad I stuck with it because of the satisfying ending.
(+) FL who isn't afraid to get her hands dirty. She isn't the typical sweet FL who wouldn't hurt a fly. She is out for revenge and is willing to fight back
(+) FL having a great character arc.
(+) Wholesome relationship between the FL and the empress.
(+) Some good plot twists
(-) The time skips were confusing but not unbearable

Acting: I've been watching a lot of idol dramas which don't always have the best acting. I've forgotten what real good acting looks like and all the actors are wonderful. In particular the best performances are from Nie Yuan (the emperor) and Qin Lan (the empress). Two amazing actors playing two fantastic characters.

Overall: I initially put off this drama because I didn't like the aesthetic of the Qing Dynasty. However after a few episodes I got use to it and ended up even liking it. So if that is what is putting you off I encourage you to still give it a chance because this is one of the best cdrama out there!
