When I was young, I fell in love with someone and always thought that I had to be with him in my life. Later, when I met someone who was kind to me, I realized that the world could be so beautiful. Xu Yi, just like her name, is lonely and isolated, as if she has nothing but herself. It wasn't until she met Zuo Qingyu that her world was filled bit by bit. His smile is like candy that children cannot resist. After tasting it, they are reluctant to let go. Everyone you meet in this world is fate. Meeting him was fate. This is also the meaning of God and the existence of God.
