Pain, So Violent and Serious

Sirius Black. A name that caused one of two emotions: spite or humour. Outcast of his family, Sirius hides things from everybody, simply so he can survive. But what happens when he meets someone who he can't hide from. Someone who, despite everything, doesn't even care? Rated for frequent swearing and slightly mature themes. Sirius/OC. Jily. Future Remus/Tonks, etc.
