Lady Yu had passed away years ago, and he hadn't remarrried since—likely because there was no woman at home to keep things in order, allowing him to be out all day.
And his daughter was in the bloom of youth, as well as strikingly beautiful.
But her reputation had been tarnished by recent events, and she certainly wouldn't marry into a good family.
It would be better to marry her off to Lord Yu; although it would mean being a concubine, the Li Family was actually getting the better end of the deal.
If Li Mo'er could manage to win over Lord Yu, her father would be safe, and his reputation would improve in the future.
Li Mo'er, however, didn't see things that way. She knew Lord Yu was an even older man than her father, nowhere close to the husband she had imagined.
Most importantly, she still had Bai Yifan on her mind and would rather remain unmarried than wed anyone but him.
So when Li Zhengtian brought it up, Li Mo'er immediately turned against him.
