I think the misconception for BP yall have comes from the fact that they are awkward af sometimes. Idk if YG skipped the media training with them or controls how they act or what it is - but BP on variety/award shows and interviews versus BP on ot4 vlives and their reality show on the BP channel seem like 2 entirely different groups. So it's no surprise to me that those that are not blinks say they aren't close.
As for ITZY's Yuna, most of the people who call her arrogant or independent are clearly not fans. Yes she is very confident and outgoing but she is also very dependent on her unnies and they're constantly saying how sensitive and thoughtful she is towards them so idk where that came from.
