What they said is wrong. I guess the MB LZ wants to know refers to the money boy. As the name implies, he is a boy who loves money. In layman's terms, it is a duck shop. A group of students have no financial ability, so they can only earn tuition or pocket money by their bodies. Of course, they serve men and women, as long as you have money. But some MB only accept female guests, not male guests. The fate of MB is mostly bitter. There was a time when I really wanted to be MB. Hey ~ I hope it helps you! Happy Valentine's Day
