Whatever/whoever it is, I guarantee it's nothing like what happened to T-ara 😅😅
T-ara's situation was caused by weirdos on the internet speaking over them and making weird, out of contexts gifs/videos that cost them their career, got them 5 years of hate and petitions asking them to commit suicide with hundreds of thousands of signatures. Nobody actually ever accused them of bullying. Plenty of reasons to not like Hwayoung but she always (kinda) defended them from bullying rumors
What's happening with your faves is He Said/She said. Not even remotely the same.
It's just a big pet peeve of mine as a stan when people that don't understand what happened with T-ara try to defend their faves with this "this could be another T-ara/hwayoung"
