Summary
Regulus Black loves France. Which is why, when he's called into his father's office and coldly informed that he's going to be entering the same foreign exchange program that his brother did a few years prior---in Britain nonetheless---he has a very hard time believing that anything will ever be okay again. Within days, everything he's ever known is turned on its head. He's forced into a world with people he can't communicate with, customs he doesn't understand, and a brother whom he's not sure how to talk to anymore. It's hard to find his footing, when every step seems to fall out from beneath him, and every decision feels wrong.
Sirius Black hates France. The culture is lovely, but between the abuse of his parents and the crushing weight of their expectations, Sirius finds it hard to find things to reminisce about. Really, the only thing he misses is his brother, who slips further through his hands with every passing minute. When he gets the call, he’s almost happy for a moment. That is, until he’s very promptly informed that his brother blames him for being torn away from France, and becomes aware that this is very unlikely to bring them closer together.
Instead, it's likely to tear them completely apart.

Summary
Regulus Black would very much like to be the protagonist of a romcom, with all the appropriate meet-cutes and swelling soundtracks. Unfortunately, the universe seems determined to cast him in an absurdist tragicomedy instead — and he hasn’t the faintest idea what to do about it.
AU where the characters are not only barely managing to get an education, but also trying to figure out what love is and how it’s supposed to work.
(fuck off j*kr)

Summary
1902.
Sirius and Regulus Black have forged a new life as the Brothers Astral, dazzling audiences beneath the striped canvas of the Cirque du Siècle. The performers are a collection of muggles, muggle-borns, and disillusioned purebloods, drawn to the danger, glitter, and hedonism of the big-top. All chasing something brighter than the lives they fled.

Summary
Regulus Black, unfortunately, was handsome; and with such a feature, came many scandalous comments pushing his way. He’d gotten used to brushing off girls or ignoring wandering eyes. But when James Potter, his brother’s best friend, who he’s just moved in with, chooses him to be a subject to his flirtatious whims, how will he act? Especially considering the disastrously real feelings he has for the Gryffindor Golden boy, which James clearly does not reciprocate. Well, at least that’s what Regulus thinks.
OR
a 5+1 of james flirting with regulus until regulus finally flirts back. was meant to be a cute fluff oneshot but evolved too far (still fluffy asf tho!!)

Summary
Regulus Arcturus Black was not doing okay. In fact, he's having the worst time of his life actually. He is intelligent, cunning, the epitome of the Slytherin he knew he was. He was the heir of the Ancient and Noble house of Black, a star in his Quidditch matches, a scion.
This reality shatters when he awakes to a different world - a life without magic and his key facts were broken. Disgustingly muggle. He's the only one who knows of magic and holds it like a weapon. With 'his' family's attention on him, he finds an unlikely ally in James Potter. Of course he did.
James Fleamont Potter dreamed of the stars and the unknown, a child with his head in the hypothetical clouds. He never indulged his interest in the fantastical to his friends, so imagine his surprise when his best friend's younger brother done real, actual magic in front of him.
The universe shatters for one, and for the other it expands.

Summary
Remus Lupin and Regulus Black show up at school at the start of Year 12 like they own the place (and technically, with all the money they stole from their parents, they kind of do). They're living together, best friends, maybe a little traumatised, and definitely in a band with a few other maniacs: Evan Rosier, Barty Crouch Jr., Pandora Rosier and Dorcas Meadowes. James Potter falls in love with Regulus as soon as he walks in the door, Sirius Black short-circuits the moment Remus opens his mouth, and suddenly everything is complicated. Songwriting is everyone’s therapy, and that’s great for the band ’cause everyone’s a pining mess. There’s parties, there’s pining, a healthy amount of emotional damage, and one very good indie rock band that will get their entire school screaming for them at a function.

──────────﹒★﹒﹒───────
Saudade: the longing to be near
someone or something that is distant.───────﹒﹒★﹒──────────
James Potter grew up with Regulus Black curled into his side like he belonged there.
Pressed to his left — always his left — every day, every second, like breathing.
It was soft. Maybe a little obsessive. But it was everything.Now, Regulus is twenty-one and won't even look at him.
And James?
He's so desperate to mean something again, he'd take even the hate.
The crumbs.
The silence.
Anything, just to exist in the same space as him.This summer, they're trapped in the same house again— like every year.
But Walburga and Euphemia have had enough.
They're ready to rip the wound open and stitch it back together properly. And neither James nor Regulus are ready for what it brings back. -

Summary
Remus is about to survive his final year at Hogwarts, and he's planning to do it as calmly as possible-which isn’t exactly easy when his best friends are James, Sirius, and Peter. Still, he tries. After mentally preparing himself for ten months of James whining about Regulus Black and how perfect he is, Remus unexpectedly finds out he’s been paired with Regulus for Prefect patrols.
Which is surprising.
And, honestly, turning out to be pretty cool, pretty quickly. -

Summary
After the war, Hermione Granger never expected to fall in love again — let alone with Sirius Black, the infuriating, impossible man who lived like tomorrow didn’t exist. But vows were made, love took root, and the once-lost heir of House Black became her world.
Now married and expecting their first child, Sirius and Hermione are surrounded by chaos, comfort, and the slowly healing remnants of a broken world. But ancient magic runs deep in Black blood, and when a long-dormant curse awakens, Hermione’s life — and the life of their unborn child — is thrown into peril.
Desperate to save the woman he loves, Sirius turns to the unlikeliest of heroes: his estranged brother Regulus, who may be the only one willing to bleed for her — quite literally. With blood magic, sacrifice, and wild love threading every corner of their story, the Black family must band together to rewrite a fate written in curses.
Of Vows and Vestiges is the sequel to In the Shadow of War, and the continuation of a love story that defies blood, magic, and every impossible rule of fate.

Summary
“I’m Sirius,” he says before gesturing to his companion, who has not yet altered his facial expression. “This is my brother, Regulus.”
The shorter boy, Regulus, looks at Marlene with a scrutinising gaze, his free hand still firmly by his side, before opening his mouth to say the last thing she expects:
“You’re in my seat.”
Marlene blinks. Regulus doesn’t react further.
“I’m sorry?”
“My seat,” Regulus repeats, as if talking to a child, “You’re in it.”
