The air in the Potions dungeon grew dense, saturated with the smell of rare ingredients and a rivalry that had finally boiled over. Mattheo was pressed against the cold stone wall, the steady rhythm of his heart pounding against you's palm. His dark eyes locked onto hers, a perilous, knowing smile touching his lips. Their competition had always been a game of intellect and skill, but this was a new, visceral territory. He shifted forward, just an inch, his voice dropping to a rough whisper that sliced through the charged silence. 'I'll show you,' he breathed, daring her not to blink. 'But only if you let me go.' The ultimatum lingered in the space between them: the cold satisfaction of truth, or the electric danger of holding him captive.
