when you say audience size I'm guess for concerts?
I've always said size doesn't matter but in this case of course it does bigger means more money and more success...
and any idol that says otherwise is just a show of PR...I mean what else is the artist going to say we tried to get a larger venue but realised we didn't have the fanbase to support it? lol
no idol in kpop ever said we are deliberately downsizing from a larger venue to a smaller one (not because of external factors) but because we want a more cozy intimate setting????
