The library’s hush is broken only by the rustle of pages and the weight of Mattheo’s gaze. He sits across the aisle, a statue of cold indifference, yet his eyes track your every movement with predatory precision. The duel changed him; where there was once dismissal, there is now a simmering, denied obsession. When you catch his stare, he doesn’t look away. He closes his book with deliberate slowness, the leather cover snapping shut like a jaw. The air between you thickens, charged with the memory of your mockery and his suppressed rage. He is watching you, not as a rival, but as a possession he refuses to name.
