What are the names of a man and a woman?

Men are called bachelors and women are called leftover women. The woman has no date, so she is the only one left. Listen to this symmetrical one, too. Of course, there are also people called leftover men. This is more corresponding.

Don't worry about it. Anyway, your brother is trying to find a man who is destined to be single, but he can't be a leftover woman. Get married as soon as possible, so that parents can rest assured that parents are not in a hurry. There are too many people who want to have children at present. In order to earn money and make a living, people often run around, but forget to find a partner, get married and have children. My parents are really worried.
