Occasionally I went through what I originally wrote and found this article. I remember that when I wrote this, I had not graduated from college yet. The classmates gathered and dispersed, and I never saw him again.
Now, he is in Shanghai and I am in Shandong. We will never see each other again.
There are a few references to things that happened between him and me in real life, but most of them are made up by myself. Bow and thank you.
