I couldn't get past chapter 3. She's supposed to be an adult, and a professional(?) RF reader but she's acting like an actual child with zero clue on what to do. Your dad's first impression of you is a scrawny rat, and yet you would still do household chores, far from being a duke's daughter, because you think that will ensure your stay?? What is this line of thinking? I still want to give it a shot though.

The MC is an adult in a child's body bullying an ACTUAL child by ruining their entire life, the mc manipulates all the adults around them just to sabotage an actual kid... like yeah she bullied the kid whose body you possessed but you didn't have to go that hard bro, the lil bully wasn't even fully at fault for how MCS bodies previous owner was being treated, it was also her parents, AKA the ones that lead the lil bully astrays fault mostly, yeah she also participated, but her parents def had more power over what had happened, MC could've just placed the lil bully somewhere where she wouldn't have any contact with the MC in a non-dramatic and less cruel way because the way the adult MC handled that was vicious asf in my opinion
Ps, I've always found adults that possess the body of a child so weird, like imagine being that child's parent, not realizing your baby's looong gone, then realizing that entire time you've been raising a fully grown adult woman/ man that was just pretending to be a child, ICCKKK
OH! and the fact they start getting all lovey lovey with kids despite being an adult on the inside????, ickkkk
