Easy we watch VTubers for what they truly are entretainers not public girlfriends filling the void of incels lifes. If they collab with males it doesnt matter its actually hilarious.
If you want a girlfriend go out and get a girlfriend. But now you say no girl wanna be close to you because you look and act like shit? Well thats youre problem not theirs. You need to step up youre game and actually become attractive for a girl to stay happy with you. Take a shower, dress decent, work on youre self confidense and you might score. Dont do it because feels like a chore and you want an easy exit pestering some egirls and youll only become more and more depressed over time.
