After five years with Harry Potter, Y/N thought her future was certain. Loyal, strong, unshakable—that’s what everyone saw when they looked at them. Until one moment in an empty classroom destroyed it all. She didn’t stay to hear excuses. She ran. And somehow, without thinking, her feet carried her straight to the last people she should’ve gone to—the Slytherin boys. Draco Malfoy, Theodore Nott, Blaise Zabini, Marcus Flint, Tom Riddle, Mattheo Riddle, marvolo riddle, and Lorenzo Berkshire—her rivals, her constant arguments, the boys who never made anything easy for her. But the second they saw her shaking, furious, heartbroken—everything changed. The teasing stopped. The rivalry cracked. And when they found out what Harry did… they lost it. Not just anger—protectiveness. Loyalty. Something deeper. At first, it’s just about picking up the pieces. Late nights in the Slytherin common room. Quiet conversations. Arguments that turn softer than they used to be. Each of them showing up for her in their own way: * Draco, trying (and failing) to hide how much he cares * Theo, always calm, always understanding * Blaise, surprisingly gentle * Marcus, protective in a loud, obvious way * Tom, intense and watching her like she’s something important * Mattheo, unpredictable but always there when she needs him most * Lorenzo, the one who makes her laugh again * Marvolo, is super soft for her and does whatever she says really. What starts as comfort turns complicated fast. Because it’s not just one of them. It’s all of them. Feelings blur. Tension builds. Jealousy sparks between the boys, but so does an unspoken agreement—Y/N matters more than their rivalry, even with each other. And for the first time, Y/N isn’t the girl who got her heart broken. She’s the girl eight Slytherins would burn the world for. Meanwhile, Harry watches from a distance, realizing too late that losing her didn’t just mean losing a relationship… It meant losing her to the very people he never thought she’d choose.
