My Stepbrother Bullies became Good??!!

Y/N goes to ******* high school, where she gets bullied because, she's just quiet. Sure she knows how to fight so she can put the girls in their place, but can she put the guys? Her mother marrieds Mr.Kim who has 7 sons. BTS. Not only are they the school bullies, they are the biggest mafia in Korea. Y/N get bullied by them but she doesn't let her mother know, but when she finds out the BTS is going to be her new stepbrothers it goes for an unexpected turn.
