Four Ways to Spell Loneliness

"Su Wei, I have a wonderful book that I would like to lend to you to read. I wonder if you would be willing to do so." "What?" ""Me and You"." "What?" "The name is "You and Me"." "Oh? Why is it called Qishu?" "It is said that no publisher is willing to publish this book because the government prohibits it. There are only 'printed copies' that are circulated privately. The book says that for a period of time in this world, all people disappeared. Haha, there was only one person left, the author. Then the author had nothing to do and wrote every day. Then he made hundreds of copies and scattered them everywhere in the streets." "Oh? That sounds fun." "Yeah, what's even more interesting is that one of my classmates happened to come across some very old printing papers that day. The ones I gave them were sorted. You know, because this book gave birth to a private research organization named 'Loneliness'." "You've whetted my appetite. Show it to me quickly. Well... I will pay you back as soon as possible." "Here. I know you're a bookworm. Read it when you have free time. Don't forget about the final exam." "You are so funny. Bye~" "Goodbye!"
