Looking for Hogwarts AU

[sostrata]

I need help! I was reading a fic and then lost it. I don't remember the author or title. It's an old fic, from the previous decade. It's Marauders Era, but an AU where Remus was in Gryffindor but didn't interact with the others until 6th year (I think). He had become infamous in the school for a messy relationship with a Quidditch player the year before. It begins with gay!Sirius wanting a boyfriend, and James points Remus out to him. Sirius then becomes obsessed with winning over Remus. They are exaggerations of their usual selves- Sirius is extremely hyper and silly, and Remus is very closed-off and sarcastic. Remus at first thinks he's being pranked, but gradually warms to Sirius, but he's sure that Sirius will break it off if he finds out Remus is a werewolf. At the urging of Remus's father, Remus sends a letter to Sirius telling him it's over, and when Sirius gets it he runs away from home to James's. James gets Remus to help calm down Sirius. In this fic, when Sirius gets upset about his family, he goes into massive magic rages that only Remus can calm him down from.

Thanks!
