1. Pick one, you aren't "close" to any of these girls, they aren't your girl friend and I doubt any of them consider you an actual friend, so again, random bitches
You are coping if you don't think they see you as a random guy who they could care less about, you "caring" about them because they are "classmates" doesn't make their relation to you any more significant
I had many classmates you I rarely ever talked to, everybody forms their own groups, just because you go to class with someone for years doesn't make them your "friend" or "someone you know"
You know about these girls about as much as you know about a woman you see at a bus stop every single day

100 times better than anything you will see on a live class, you are obviously the orbiter type of guy, else some "classmates" merely being on camera showing their face wouldn't arouse you at all. I can see you being the type to buy an onlyfans subscription in the future, because its like the "connection" means more to you than the actual sex, and there isn't even a "connection" there is its nothing but delusion, and that's no different that the delusion of guys paying for onlyfans subscriptions because it "feels like a relationship" or "feels like I know her"
