I really can't explain why I'm so sad all the time, so I'll use this essay to express my feelings. Nothing can be done, nothing can be undone. But when I see bad comments, I want to cry. How can people be so bad? No, it's not my intention. It was all an unwarranted disaster, and it was all a failure to understand one's fault. Even a little change is good, don't let him leave without doing anything. Goodbye, such a sincere smile that I have never seen before and only discovered now. May you get more genuine smiles in your next life.
