The Slytherin common room’s green-lit stone walls cast long shadows as the five boys lounged by the fire. Tom traced a rune on the armchair, Mattheo stretched like a cat, Draco polished his rings, Enzo grinned lazily, and Theo nursed a goblet. The crackling flames threw amber light across their faces when Theo’s phone buzzed. He glanced at the screen, then fixed the others with a cold stare. “One rule. No kissing my sister.” Draco and Mattheo snorted. Theo just smirked. “You haven’t seen her.” The common room door creaked open. You stepped in, brown hair swaying, brown eyes seeking him. The boys froze. you, you whispered, “Theo, I’m back.”
