"Ok, then what are some other 'assumptions' of yours?" Regulus asked. I set my tea down and stared at him.
"You think coffee tastes like dirt, you prefer your mum over your dad, you convince yourself that the reason you hate your brother is because he's irritating and not because you actually miss him, when you were little you wanted to play professional quidditch, and your dream is to live in the French countryside."
"I hate France," he said.
"Just assumptions," I repeated again with a small smirk.

In the Shadows | Severus Snape
Sylvia's first choice had always been Sirius Black. She had fallen for him easily, much like most other girls at Hogwarts, drawn in by his irresistible charm and magnetic confidence. But as time went on, cracks began to form in their relationship. And after a year of dating, new feelings and doubts begin to seep their way into the crevices, leaving Sylvia to realize that her heart might not have been as certain as she once thought. Severus Snape, on the other hand, was never supposed to be an option at all. He was impossibly aloof, always brooding alone in the shadows of Hogwarts. He was the last person she ever expected to care for. But throughout a year-long partnership with him in Potion's, she begins to see another side of him, one that nobody else ever bothered to uncover. The dedication he poured into his work. The rare kindness he managed to mask so well. And slowly, her dread of working with him blossoms into something she never anticipated, a connection she never knew could exist.

Madness | R.Black
Elara June Lupin was the beacon of light in her family - full of laughter, wildflowers in her hair, and a heart that burned like the summer sun. She was brightness and bravery, the kind of girl who believed in hope even when the world told her not to. Regulus Black was the Slytherin Prince - cold-eyes and silver-tongued, all sharp edges and secrets. A boy raised on pure-blood legacy and quiet survival, with a future that was already carved into stone. When they're paired together in fifth-year Potions, everyone expects the worst - light and shadow rarely mix. But slowly, between simmering cauldrons and late-night study sessions, something shifts. A glance held too long. A lingered touch of hands. A truth shared in the dark. As the world around them begins to fracture under the weight of a growing war, Elara and Regulus are forced to choose: loyalty to the names they were born with, or the love that defies it all. Because sometimes, the brightest stars burn out too soon. And sometimes, love is the most dangerous rebellion of all.

Cracks [Regulus Black x Muggle]
[Regulus black x original muggle character] [enemies to lovers] [kind of a slow burn] Flora, the muggle half-sister of protective older brother Remus Lupin, finds herself hidden away during the First Wizarding War for fear of werewolf attacks. Her life is lonely and quiet until Regulus Black, a former Deatheater and insufferable, arrogant prick, is also in need of sanctuary. Or, a story in which Regulus never expected he would fall in love with a muggle. [enemies to lovers] [regulus black x original muggle character] This fic was inspired by WizardGod's 'dirty old town.' I did have a similar concept prior to reading her work, so it's more accurate to say it motivated me to write this. The setup is generally the same, but this story is very different. WizardGod's fic is brilliant and I highly recommend it if you haven't already read it! Barty Crouch Jr. is tagged but he doesn't come into the story until chapter 23.
