I'm a Fool, but You Can't Call Me a Fool

I'm a fool, but you can't call me a fool. In traditional fairy tales, an honest man who is extremely dissatisfied in modern society and has been frustrated all his life finally gets the same chance to start over at the bottom of another strange world. There is only one thing in this life, do it if you don't like it, do it if you don't feel like it, do it if you want to do it!
