Unknown Ro'meave girl

(Y/N) is just a normal girl to the outside world, but a liar to her school. Nobody thinks that she is apart of the family because she doesn't compare to her eldest brother, Garroth. Her other older brothers, Zane, who is older than her by two years and is a freshman. And Vylad who is one year older and is also a freshman. She is a sophomore even though she is the youngest. Her parents sends her a tutor who beats her, she doesn't tell. Her father hits her sometimes but it's very rare. (Y/N) hears something she doesn't want to hear, what does she do?
