Sirius Black and Remus Lupin. I legit didn't even know that gay people existed until I discovered
ff.net around the age of 10. Fics about them saving Harry from the Dursleys and raising him as their own in like a cottage in the countryside were my induction into the fujo life. Even all these years later, though my feelings for the franchise as a whole have soured quite a bit, I still have a huge soft spot for this ship. I'm glad the marauder fandom has weathered the storm and is still going strong, largely independent from the greater HP fandom.
