Nugu groups don't get the protection from fans. Theres so many examples but Busters is the best example.
Chaeyeon and Yeseo were especially young when they debuted in the group. Members from nugu groups are in more danger than big 4 groups as seen in what happened to Chaeyeon on that kids show. She suffered both verbal sexual abuse and physical abuse.
None of this would have happened with a big 4 member cause they are powerful enough that nobody would mess with their idols like that.
