Rushia were quickly abandoned by most of her fans after they know all her flirting was fake because she maybe had a relationship with some idol guy
Rushia instantly got almost one million subscribers on her new channel. Don't project your unhealthy parasocial obsession on to "most" fans.
And also most of her fans didn't care at all for what i've seen, only a vocal minority as always. Even her top donor who was shocked at first come to accept it if it was real. Lot of peoples were sad that Rushia had to go for something like this
From a few stuff I saw I got the feeling many of those were not even her fans but actually vtuber hater who smelled blood after a few of the kimoota started the drama and they fueled it up.
"after they know all her flirting was fake" <- and tbh I can never understand this, how can the fans possible think the flirting are real?! She can't possible have romantic feelings for all of them right?! It's a play and the fans understand and like that. Well except a few delusional individuals I guess.
