Sirius Black has a crush and it's time for him to make a move before:

1. Someone else does

2. He gets blown to pieces in a Death Eater raid.

Luckily, James and Lily have just gotten engaged and weddings are the perfect setting for a date. Romance. Low lights. All of that. And, even more luckily, his crush has just walked into the Leaky Cauldron.

This is set in 1979 when Sirius is a member of the Order during the First Wizarding War.

But I've not specified what User is - you can be a fellow member of the Order, a childhood friend, or anything you like! There is also multiple openings for different pronouns.

My version of Sirius isn't a playboy either - he's flirty, handsome and charming. But he is romantic deep down and wants a relationship.
