It's quite normal in Japan

If you've watched Midnight diner, you know what I'm talking about. There are normal Japanese girls being sex workers, just to accumulate money for college, and they do quit when there's enough money made. One call girl ran into her divorced father, whom she hasn't met for years.  The guy accidentally called his daughter for service to his home. She saw her own photo in his living room and ran off.

Prostitution is the oldest career in human history. It's not glamorous but it's certainly not a crime and shouldn't be one.
