YESSSSS, THANK YOUU!
I remember mc got adopted as the third child or something. She got and older bro and sis. She had different hair/eye colors I think because of a certain magic casted by a cat to protect her identity. She’s strong and i remember her dad and bro was shocked when they knew of her strength after bring adopted.
