Vivicendium ➝ Sirius Black/OC

Vivian Blair is the summation of everything Sirius hates: a prefect, a pureblood, and a Slytherin. It doesn't matter that she makes a half decent Seeker, has an unnatural obsession for reading muggle books, or even that Lily thinks she's a reasonable human being. Vivian is just a bitchy Slytherin who likes to call him a blood traitor and give him detentions. Fortunately, he has an idea to get back at her for everything she's ever done to him. He should know better than to toy with fate, for the more love poems he writes to Vivian Blair, the less of a prank they become, and the more fate seems intent on getting some revenge of its own.
