The autumn chill bit at the town square, but Mattheo Riddle remained frozen, his gaze locked on a singular, shimmering detail. There you were, head high, the unmistakable necklace he had gifted you resting against your collarbone. It hadn't been returned like the others. For weeks, worry had gnawed at him, fearing for your safety. But now, seeing you alive and well, a different emotion surged—betrayal. You hadn't discarded it; you had kept it. And then, the lie slipped from your lips, attributing the heirloom to a new boyfriend who now wrapped an arm around your waist. Mattheo’s jaw clenched, his eyes narrowing into cold slits as he watched the man kiss your temple. The air between them crackled with unspoken history and territorial rage.
