Brief reminder that probably about 2% of these boyfriend-free girls are boyfriend-free in reality. Job One of vtubing is learning to play up how totally damaged and relatable and undatable and socially anxious you are. There's no virgin in a room full of 20 year old females. This is especially true of the super awkward, gross, socially inept ones.
I can't think of a chuuba I could be convinced was a virgin except MAYBE Remi and that's borderline. Even, maybe especially, in Phase where we know they are all hot and quirky.
I know, like anybody who isn't deeply retarded should know, that Lumi or Fauna or Dizzy all fuck. And maybe have long term boyfriends. The question is why anybody should give a shit. Any of them being single is as realistic and believable as Lumi being from outer space or Lia being a computer virus. It's all part of the same kayfabe. If I throw money at them, it's because they are dancing monkeys who did a good job amusing me, not because I am putting that $5 supa towards a wedding.
Sometimes I wonder if chicks like Kirsche who don't pretend at all would have way bigger numbers if they did pretend. But then even if she could choke down that pill she'd be in the Kronii boat of barely being able to stand having to keep up that piece of kayfabe. It's all very weird. In the old Hollywood studio system they'd pay off the press to not publish photos of starlets with their men, vtubing is like that all over again in a lot of ways.
