I used to listen to other people telling stories, but now I want to tell my own stories to others. After thinking about it, I don't know how to start. Whether it's from the first meeting or the end, the story is too long and too scattered. From that school, that building, that dormitory, those nights we spent together, the dramas we watched, the games we played, the books we read, the notes we memorized, what Song Wei misses is not the youth of those years, nor the stories of those years, but the people who walked into her youth and had those stories with her. The Su Yao who tolerates her in everything, the forthright Jiang Yun, the gentle, silly and sweet Lin Ning and the proud and complacent Ding Yiqing. From the beginning to the end, from a backward third-tier small city to a prosperous first-tier city, we are with each other for the rest of our lives.
