The Facade of Us | Sebastian Sallow x Reader
"We can't keep tipping the scale of friendship, Sebastian." I say, my voice trembling as I meet his gaze. His expression falters, vulnerability flickering across his face. "Then tell me, Y/N-what do we call this?" ββββββ ββ βββ Returning to Hogwarts for your seventh year, you're still celebrated for your heroic deeds during fifth year. But fame comes with its challenges, and nothing complicates life more than unspoken emotions. Over the summer, you, Ominis, and Sebastian made a solemn pact: no matter what, nothing would break your trio apart. One condition, however, left you uneasy-Ominis forbade any romance between you and Sebastian, convinced it would only bring chaos. You agreed, believing your feelings for Sebastian were purely platonic. But as the new school year begins, the line between friendship and something deeper began to blur. Leander Prewett, persistent as ever, refuses to take no for an answer when it comes to his infatuation with you that started in your fifth year. Desperate for a solution, you turn to Sebastian for help, thinking it might finally end Leander's advances. Little did you know, this small request would set the stage for a far more tangled web of emotions and forbidden feelings.Complete![In the shadows of Blood and Snakes [Sebastian Sallow x Gryffindor MC]](https://img.wattpad.com/cover/373794261-256-k579189.jpg)

The Unyielding Ravenclaw of Birmingham
CURRENTLY BEING REWRITTEN. She's a Shelby. Trouble runs in her blood. Dragged from Birmingham to Hogwarts, Larissa Shelby carries more than her family's notorious name-she carries ancient magic the wizarding world thought was long buried. But Hogwarts is not all as it seems. Curses whisper through the shadows, relics hunger for blood, and every choice drags her closer to the edge. Enter Sebastian Sallow: clever, infuriating, impossible to ignore. He's as reckless as she is sharp-tongued, and together with Ominis Gaunt, they're pulled into a spiral of secrets Hogwarts was never meant to reveal. As Larissa flirts with power-and danger-she has to ask herself: is she carving her own path, or stepping into the darkness her family was born to rule? Because at Hogwarts, survival isn't about following the rules. It's about rewriting them.
