This book is composed of multiple independent stories, some may be long or short. Life is full of infinite possibilities, and human emotions are also unpredictable. I hope you understand.
If you don't like it, please don't come in and don't disturb it.
Some of them are homework, so they seem a bit messy.
Intention: do what you should do, stop where you should, respond when you come, and don't stay when you go.
