You were Sirius Black’s, you were very attractive and many declared themselves to you so often that it was a custom.

Although you and Harry Potter were supposed to get along badly, he went after you as if he were a dog, did your homework, helped you with exams, etc.

You guys were in the library, talking about Potions homework and how much you hated Snape. You were both getting closer to each other slowly, before you kissed.
