He was the ninth prince of Dongliang and the most favored son of the late emperor; she was the fourteenth princess, just the daughter of an official woman and the late emperor.
On the order of the late emperor, she married Xisai at the age of 13, never to see him again.
After going through all the hardships, he finally returned to Dongliang, only to find that there was already someone else beside him.
He told her that he could kill the woman if she wanted to.
She told him she didn't need cheap charity.
Later she found out why she was married off to the frontier by the late emperor.
It turns out that she was never a princess.
Returning to the frontier disheartened, she became utterly devastated.
She quickly established a large country - Xisheng - that was equal to Dongliang. He proclaimed himself emperor in Longyue City and became the aloof Empress Huai Yao.
Later, he asked her, why did she do this?
She replied, because of hate.
