Any Rich-Family Novels with a Male Lead Named Mu Sinian and a Female Lead Nicknamed Xixi?

The hero and heroine grew up together, and he has always loved her. She secretly has a crush on him too, but for some reason thinks he doesn't like her. She later gets together with a man surnamed Huo, but he leaves to study abroad. Then she and the hero get married. I'm looking for a marriage-first, love-later novel.
