Every trace of my entire youth is engraved with the same name. When I see the trees on the street and the clouds on the horizon, I will think of him unconsciously. I remember the bubble tea he ordered for me, and the sparklers he lit up for me. Those memories supported me through difficult days and made me think I was special at one point. When I was young, I often wondered, is it possible? Even if it is one in ten thousand, what if I am the heroine in his story? I have said goodbye to him countless times, on the phone, on WeChat, face to face, every time without pressure, because I know there will be another meeting. But this time is different, Xu Jiamu, this time I really want to say goodbye to you. “Goodbye, Xu Jiamu.”
