Have spoilers. I warned you.
I can summarize this series plot in two-sentences. If you remove Fukangan (the imperial guard) from the story. It would have still ended the same way.
Everything in the middle was just a waste of time.
Fake love triangle. When I think about it.. there was no love between any of the characters. Or they couldn't convince me that these 3 characters even love each other. Fukangan has a sad backstory. Honestly, this character acted like the end boss of a video game only to become the NPC guard of the palace gates. 7th princess, I liked her character until the end in which did an "M Night Shyamalan move" (added a plot twist). Mongolian Prince also did a "M Night Shyamalan move".
I normally don't write reviews but this series was so bad that I need to vent.
