So she gets reincarnated and tries to change the father-son duo through being nice, caring, and loving. Sadly this doesn't work and now they're crazy and overprotective of her. When you think everything has been resolved the bratty prince tries to cast them out because he thinks they tried to steal the female lead. There's also this one girl who's supposed to torment the original FL but gets along with villain's mother (current FL of story) and they both like cats!
