You were Sirius Blacks Daughter. He only saw your mistakes. But he saw Harry as perfect. Every time you would bring it up he would get mad and walk away

it was dinner time at the house, you were sitting next to Fred. Harry walked in the room. You watched as Sirius got up and hugged him. Jealousy filed you, Sirius never hugged you. Fred put his arm around your shoulder. The two of you watched as Sirius went back to his seat and Harry sat by him.

“You okay love?”
