[WTF]'s manga / #manipulative mc(2)

I just started reading this and the mc is getting into my nerves but still gonna read it hoping for some character development

This has potential but it pissed me of, she's a grown adult in a body of a child, it means she has a better skill in assessing situation plus she has the advantage of knowing the future where they became villains, that alone should have made her realize that there's no way that uncle will set them free, but she chooses to stay still for so long to the point where the kid's health declined. Their future won't change at this point since the other kids will probably become a villain sooner or later from that experience. If the story progress as what i expected, ill probably drop this ://
