no I'm pretty sure the sister wasn't treated like her in her past life. The reason mc was treated bad was bc she molted to have red hair, which is like, a bad omen or smth. Yeah the little sister's ability is a mutation but I don't think the family head would see it as a bad thing bc her ability's useful
honestly I lowkey get the vibe that she's an evil character, in the past life she should've known that her powers were harmful but she killed ml anyway. Well what I said was based on logic and info we already know, like, no one else was treated badly except fl for her hair color. The little sister looked lifeless whenever she came up, and yeah I'm hoping she was never treated badly. I'm honestly hoping that mc and the little sister becomes close bc everyone else in that family looks like dirtbags
I feel bad for the little sister, it seems like instead of the FemMc the little sister will be stuck in that household.
