Prosperity Is Like Icing on the Cake

I have a friend who is very rich, so rich that I want to kidnap him. I have never seen an emperor, and the history books I have read are not enough to help me describe what an emperor looks like, but I always firmly believe that my friend is an emperor. No one knows where his money comes from, but it seems to me that he will never be able to spend it all. People who know him will say that he lives a very happy life, while people who don't know him will say how could he not be happy? But only I know how much his happiness costs every time. Following him, I discovered a hidden world. It was a prosperous world.
