This was a beautiful drama, everything from the makeup and costumes to the fight scenes was done exceptionally well. Acting was on point the entire time, it wasn't overly funny and cutesy like china likes to do, and it wasn't boringly serious either, they hit just the right note.

Ren Ruyi and Ning Yuanzhou are perfect main characters, they both stand briliantly by themselves, and form a perfect couple together. The Female Lead, unlike what is popular, is not dependant on the ML, and doesn't cry every 5 mins. She's strong, dependable, smart, and acts like a mature grown woman instead of a child. The ML is the best at what he does, but instead of being cruel like most other drama leads in his position, he is kind and affectionate towards his brothers. When they are together they form a beautiful sight.
The Princess is the one who really rises up throughout the show, it is so rare to see a princess show such growth, it was an amazing progression throughout the season. I would love to see more of her in a 2nd season.

The soundtrack was great, the combat music for the female lead is so hype it always gets me giddy with excitement.
I've already begun rewatching the show.
The only flaw to point out is the rush in the last 6 episodes, with the amount of content they rushed through, they could've done an entire 2nd season for the show instead.

Definitely watch this, you will not regret it.
