>>86030485People are organized very strictly into narrow age groups and there's almost never a good explanation for why you even know 18-year-olds, so it looks like you go around to high schools seeking them out. This got a little weird with mandatory college, so it's acceptable for students 18-24 to have sex with each other, but a college student and a graduate is weird now. Her mistake is calling this pedophilia, like you can't be suspicious of someone unless you have a label to justify it with.
Obviously most people find this weird unless you have a good reason, but even then most people don't ever go out or join groups, so they might still find your explanation sus like "we worked together first" or "we go to the same church." She's basically trying to make the case that her watching one of Erina's streams is pedophilia, which is just retarded. You don't wear a sign with your age on it when you meet people, so it's not like you'd know going in.
