All I Want - Regulus Black

"Her heart sank into her shoes as she realised at last how much she wanted him.
No matter what his past was, no matter what he had done.
Which was not to say that she would ever let him know, but only that he moved her chemically more than anyone she had ever met, that all other men seemed pale beside him"

Regulus Black was bought up in a family where his parents and those before them believed that pure-blood wizards were more superior to any other wizard and those who weren't purebloods, were considered filth. Regulus Black, the perfect son, the Slytherin Prince, also believed all of this up until a certain half-blood witch who was best friends with his brother decided to come crashing into his life.

She heard the rumours, she had heard all about the young, charming slytherin boy who tended to keep to himself, who admired the dark lord, but for some reason, she just couldn't bring herself to stay away from him, after all, every Hufflepuff needs a Slytherin and every Slytherin needs a Hufflepuff.
