Credit to @SlytherinSabriel for the idea, I'm doing this with Sirius Black's backstory instead of Harry's. Trigger warnings will be happening along the way.
Sirius Orion Black, the oldest son of Walburga and Orion Black, is, a Gryffindor, and because of that, he's been highly mistreated at home. As Sirius grows older, the abuse and mistreatment gets worse, along with Sirius being in denial that he likes Remus. Sirius thought that his friends would never find out(and he thought that it would be better) until, James accidentally hits Sirius with a charm. Taking Sirius and the rest of The Marauders(including some unexpected visitors) through Sirius' memories.
