Sirius rejected you, thinking you were another spoiled Pureblood princess. When you transfer to Hogwarts, he realizes how wrong he was.

Eat your heart out, Sirius.

"I don't give a damn 'bout my reputation
Living in the past, it's a new generation
A girl can do what she wants to do and that's what I'm gonna do"

He remembered how she'd behaved at the one disastrous dinner their families had together. She hadn't said a word unless asked a direct question and rarely even looked up at anyone. She seemed cowed. Weak. The sort of girl who could never keep up with Sirius's reckless, rebellious nature. There was one brief flash of anger when he'd asked her if she bought her knickers pre-twisted, but it quickly faded as she ignored him and returned to eating her pudding.

But this girl...was a different creature entirely. A streak of hair was dyed blue, and she was wearing knee-high leather boots that were definitely not allowed by the dress code. Her uniform shirt was unbuttoned enough that he could see the t-shirt underneath.

The Clash? She listens to Muggle rock music? And is that...a nose piercing?!
