Everyone knew Sirius Black hated his family. What nobody knew was that he wasn't the only one. Y/N Black had spent seventeen years learning how to be the perfect daughter. Sirius had spent seventeen years learning how to rebel. Regulus had spent fifteen years learning how to obey. And somehow, all three of them were still living under the same roof.

And Y/N was the one who stayed in the middle, keeping everyone happy. Until she realised she didn't want to anymore.
