This is a story about first love and last love. No matter what she experienced along the way or what she did to him, Chen Xiao always believed that Liu Yucheng had never given up on loving him. Fortunately, he had never doubted it. She has never forgotten the prediction made by the frail old man in the underground passage to Liu Yucheng: "For a long time in the future, you will think about one person when you open your eyes, and think about another person when you close your eyes." But she never thought that she would be the one who finally fulfilled this sentence.
Liu Yucheng said: "No matter how much you deny me, Chen Xiao, there is one thing you can never deny, that is, we always have a heart that wants to be together."
Chen Xiao said: "Liu Yucheng, for a long time I wished you would disappear, but for a longer period of time, I was afraid that I would never find you again."
"Fortunately, I didn't find you, but you remembered the way back."
