In the not-too-distant future, post-disaster humans have eliminated the restrictions of race, country, and language, and built ideal cities one after another.
Consumerism makes people crazy and makes them no longer human. The strife between people makes some people as lowly as pigs and dogs, and some people spend money like dust. Now that all kinds of pain are gradually being numbed by pleasure, people are pursuing greater happiness.
When desires expand, what else will be watching humans?
Just a novel.
