What is the end of Xiasha?

Finally, Sha Mu Chen knew that it was actually the real Susie (written in the book), but he didn't go to Xia Xiaoxi. He realized that he had been in love with Susie for so many years, and he fell in love with her from the beginning. Susie also knows that Xia Xiaoxi is wonderful in her world even though she has changed her identity and environmental background. Finally, Xia Xiaoxi went abroad to study, and Xu Xiang chased him. They were very happy together (I can't remember exactly).
