literally
Simple, they crave something like a badass heroine/person reincarnate to a villainess who is responsible and wise. Not a naive child. She's still young and not know anything, kinda understandable it would come out a little boring. But hey, every child always acts like they're annoying but cute. They easily forget things (like me :D) but they learn fast. If they don't like the mc, no one should be judging (except if they hate her in an unsensable way.)
ikr? and the child was literally abused and wasn't taught how to stand up for herself because of that? she's not even reincarnated?
People in the comment really hating on a child. What?
