It's been ten years since Eleanor Blackwood left Hogwarts. She wasn't planning to come back - not really. But when the offer came to return as a guest lecturer in Alchemy, she said yes before she could talk herself out of it.
She tells herself it's not about the past. Not about the people she left behind. Definitely not about him.
Sebastian Sallow is still at the castle. Still sharp. Still complicated. Still feels like something unfinished. And then there's Garreth Weasley; kind, familiar, maybe something more. She doesn't know yet. But part of her wants to find out. But the thing is some feelings don't just fade. Some stay quiet until you walk back into the same room, and suddenly they're loud again.
And that one question she's tried not to ask for years:
If he had just answered... would everything be different?
A slow-burn, second-chance story set years after Hogwarts Legacy. For anyone who's ever tried to move on but kept looking back anyway.

Passion | Sebastian Sallow
Sixth year was supposed to be a fresh start, but Sebastian Sallow has been pulling away, and Vanity Steel can't figure out why. When a night out brings them back together, they fall into an unexpected fake relationship that quickly becomes something far more complicated. But just as everything begins to feel real, Vanity is given a once in a lifetime opportunity. The only catch? If she takes it, she has to leave Sebastian behind. And she has no idea the relationship was never fake to him at all. ---- "Alright, just take it easy," he said, resting a hand on her thigh without a second thought, a reassuring touch meant to ground her. But for Vanity, the warmth of his hand on her leg was electric. Her eyes were drawn to it, her mind racing with thoughts she couldn't stop, thoughts she didn't dare say aloud. He must have noticed her staring, because he smirked, glancing at her. "What? My hand doesn't bite, I promise." ---- This story includes 18+ content and spicy scenes, uncluding breeding kink and hand fetishes. Because of that the characters are 18+.

Sebastian Sallow and Gracelyn Marwood have always been partners in crime, best friends, and the source of each other's greatest mischief. But as they enter their final year at Hogwarts, something shifts. Teasing glances linger too long, friendly duels grow heated, and unspoken words threaten to break the delicate balance they've built. Sebastian is usually confident and a flirt, yet utterly infuriating when it comes to romance. Gracelyn is self-confident, radiant, and yet only one who can make him falter in his steps. When jealousy sparks, secret feelings unravel, and choices lead them down unexpected paths, they're forced to confront the undeniable-this has never been just friendship. From the tension-filled halls of Hogwarts to stolen moments in the Undercroft, from whispered promises by the lake to the life waiting beyond the castle walls, their love is a slow-burning, all-consuming fire. But Sebastian's past haunts him, and his greatest fear isn't the darkness he once embraced-it's his own mind telling him he doesn't deserve her. Will he finally let himself have the future he never thought possible? Or will his fear of falling cost him the one person who's always been willing to catch him? Friends to something more. The best kind of madness. *BONUS AU CHAPTERS AT THE END*Complete
