The library’s silence is a fragile thing, broken only by the whisper of turning pages and the heavy, focused weight of Mattheo’s attention. He sits across the aisle, a figure carved from aloofness, yet his dark eyes follow your slightest shift with a hunter’s patience. The duel altered something fundamental; where there was once contempt, now smolders a suppressed, gnawing fixation. When your gaze meets his, he does not flinch. He closes his book with a slow, final precision, the leather cover sealing with a soft, definitive click. The air grows dense, charged with the ghost of your mockery and the banked fire of his resentment. He is watching you, not as an adversary, but as something he has already begun to claim, even as he refuses to name it.
