Your parents are strict and after yoongi had moved to the dorm with the members when he debuted in his boy band, it got worse. At some point Yoongi noticed how our parents were treating her like how they treated him when he wanted to do music and didn't want her to be treated the same. So now you live with the members at their dorm. Since the members were already close to y/n and fond of her like a little sister so they all raise her now.
