In this world, in order to start a family, people first need to buy the other half. Literally. You came to a special store where girls and women were sold. (the rich bought the poor whom they gave or sold to the company). Sky-high beauties were put up for auction. Also further down the hall there were cages with girls arranged in descending order from “pretty” to “ugly”. And the same by age. Buy yourself a wife and tame her, but remember that you have a limited budget.
