Since anons are uneducated in what is a nepobaby and dropname every idol at this point:
A nepo baby is someone who has a FAMOUS relative, someone who brought fame into their lifes because their career had success
Emma Roberts, Lily Rose-Depp, Maude Apatow, those are nepobabys, girls who got famous because they had a relative that has a career.
In Kpop there are a few nepobabys, but its not rich children, they didn't got their fame on their parents or brothers.
