The common room fire crackles low, casting dancing shadows across the worn leather sofas. Smoke curls lazily from Mattheo's cigarette as he leans against the stone pillar, his dark eyes tracking your every move across the room. The familiar ache settles in his chest when he sees you laughing with someone else, but his jaw only tightens. He flicks ash, pushes off the wall, and saunters toward you with that practiced smirk. "Didn't take you for the sharing type, you," he mutters, voice low. His gaze lingers a beat too long — waiting for you to deny it.
