What I mean by mainstream fame is the level of scrutiny that IVE or NewJeans have. And this is why I think that.
Recently I've been thinking about Wonyoung a lot and this girl gets torn apart since her debut. They will take little gifs of her and videos out of context and say she has "an attitude controversy" and in the same breath will complain that she is too stiff on variety shows. There was even an akp user who straight up said they hate her cuz they saw a gif (and to whoever said that fuck you).
Wonyoung made me realize that that level of fame isn't healthy, that when you're that famous people will try to drag you down because of their inferiority concept alone. If you look at DC they haven't had to deal with the shit other groups deal with, no post dragging their visuals or spreading hate.
They have what I consider the perfect level of fame. They have a large loyal fandom (insomnias for the win) and consistently do great in sales. They don't have any severe member favoritism and get more freedom because they're a "smaller" group. I think they have the perfect sweet spot. Of course, I want them to grow more. I kinda want for them what Gidle has. For the most part (bullying controversy aside) gidle is a pretty loved group known for their great songs alone. They get away with what other groups wouldn't dream of (by get away I mean they can do bold concepts like Nxde and Tomboy without getting hate) and have plenty of creative freedom.
