Excellent drama! Unlike most historical or period c-dramas and k-dramas, the female lead is strong minded, strong willed, knows what she wants and isn't afraid to speak up for herself and others. In other words, she isn't a damsel in distress constantly making mistakes and looking for the male lead to save her. Additionally, the script writer did an excellent job, as there isn't any super long and unnecessary conversations between the characters. I also like the fact that the plots are not dragged out for 30 episodes; each scandle is resolved within 2 episodes and I love it! This is the type of historical drama I dreamed of, but to be honest I am shocked that I found. For example, when the female lead actually defends herself, take actions, and doesn't back down, I am pleasantly surprised because I am not used to this level of female confidence in c-dramas. I love it! I was turned off by the king's character, but realIstically, in every culture throughout history, kings most likely acted like this king (e.g. rude, arrogant, hasty, etc). So, while I hated his character at first, I've grown to be okay with it because it's a realistic character trait of kings throughout history. I am currently on episode 23, at the 36 minute 45 second mark to be exact and the queen's brother as fine as he is, just made a stupid mistake. I had to pause, to remember that it was culturally acceptable back in those days to disregard women, and slaves. So I decided to write this, while I allow my emotions to cool down.

GREAT DRAMA
GREAT ACTORS
GREAT WRITING
GREAT FILM QUALITY (RESOLUTION)

Edited on 5/6/21:
One thing that kind of throws me off a bit is the fact that the emperor was going to rape the main lead but she was able to get away. She ends up falling in love with the emperor who wanted to rape her, and him with her. Most dramas have some level of toxicity but this is problematic because it romanticized rape, which is the reason why I dropped the rating from 9.5 to 9.
