The so-called unforgettable past is nothing more than two or three love songs and two or three things about youth; I still don't understand why thinking about someone when I was sixteen or seventeen made me cry. What I experienced when I was sixteen or seventeen can persist in my memory for so long, persist until I can tell it calmly, persist until the protagonist of the story changes from myself to fiction, persist until I write these. It is nothing more than an afterthought in my imagination, whether it is moaning for no reason or showing sympathy to each other, it is better that we parted ways at the end of the song.
