Sirius was always known as the nice gryffindor but he never acted like that to you.

He scoffs every time he sees you, and calls you stuff like “wh0re” and tells you, you are just like your mom that is in Azkaban for some stuff. Little did he know how abusive your dad is and how his words remind of your dad's word. You are in the great hall for dinner and the only seat open is next to sirius, when he sees you sit down scoffs at you.
