Personally, I think the fans should just shut the hell up. 😂
The real problem in BM isn't how they perform (they're young, not even 20 except Ruka), it's what they have to perform. I'm talking about their songs, of course. And honestly, their choreos aren't as good either. A group like them should focus more on the vocal and rap performances, just like Mamamoo did. I'm pretty sure they could pull off something like them, but that's not the YG style.
