The drama should have been titled "The Forgiving Princess" as the FL forgives everyone that has plotted, betrayed, and used her in order to gain power.

I was really impressed with Zhou Yi Wei's portrayal of Xiao Qi (the ML). Loyal, faithful, honorable, stoic, and strong. I don't normally cry while watching Chinese drams, but I cried when Xiao Qi wept over the death of Gen Song Huai En.
I wasn't impressed with Zhang Zi Yi as toward 2/3 of the drama, she was essentially wooden and expressionless. The sets and costumes were gorgeous. And the song End Of The World was simply beautiful.
