Rugged Northwestern Man Vs. Sweet, Soft Heroine, Yandere Hero

Please help me find a book I read a few chapters of before. The male protagonist was from the far northwest, while the female protagonist seemed to be from Haicheng. Her surname was Ning, and her grandfather may have been called Ning Jianguo. Everyone in her family was a civil servant except her. She was an only child who studied painting, was forced to break up with someone, and married the male protagonist.
