Have you ever been like this: When you had no definition of love, someone appeared and taught you what love is. When you truly understand love, he pulls away again, leaving you with only sadness and memories. Faced with the betrayal of love, Xue Bi chose to go abroad to escape. She thought that she could forget everything about him as long as she stayed away from him. But being willing to forget someone you once loved so much, is that love? She rejected all suitors, only for him. When she came back three years later, she accidentally learned from her father that the betrayal was just a play, a play that her father made to prevent her from falling in love early. But Yan Shuo already has a girlfriend by his side. Is it a transference or something else? What can snow do? After all, I missed it! How will she face Yan Shuo's humiliation and Yan Shuo's doting on his girlfriend? Until one day, Xue received a call from Yan's mother saying that Yan Shuo was missing and no one could find him. Xue entered the room that Yan Shuo was not allowed to enter - it was all Xue and Yan's things. It turned out that she was right to insist. But what happened to make Yan treat her like that? All the answers are in a journal. That diary fell into the hands of Yan's girlfriend Shen Manwen. Will she give it to Xue? Can Yan and Xue be together in the end? How should I pay back the happiness I owe?
