Yan Fei: I have never liked anyone else, and I don't know how to be nice to you, but I know my own heart very well. I used to think that I could be alone, very free, and very happy. But after meeting you, I realized that two people can be so good together. It seems to be better than alone. Qin Yuxin: You and I only have this life, only this life. I want to waste each other with you, spending the short silence together, the long meaningless time. Let's waste away the old and delicate universe together. It is best to sum up the lifelong promise. May the piano and the harp be at your disposal, and it is best to be quiet.
