It's Been a Hundred Years Since the End of the World, and I Just Woke Up

[The end of the world + no immortality + no games] I don't know! How many humans are left in this world? From the moment I woke up, in order to be able to find human settlements. We have been wandering alone for three years in this apocalyptic wasteland that has lasted for hundreds of years. Now we have finally found the one, the only place where humans are still possible. Are human beings in the post-apocalyptic world the same kind of people who love each other? Or hunter and prey hunting each other?
