This is a story after the collapse of the world... There are only different stories of various human beings at the end of the world. Watching how they survive step by step, this is the story... (Not a cool novel, not a time travel, not a golden finger, no system.) (Can you add a bookshelf if you like (｡ò ∀ ó｡))
If you really want to read this book, then I can only say that your taste is really cool!
