A forced life-bond ties Mattheo Riddle and Y/N after she saves him from death, linking their emotions but not their thoughts. He rejects the bond violently, using cruelty, distance, and other girls as distractions while repeatedly trying—and failing—to release himself, never realizing the attachment forming beneath his resistance. Y/N endures the emotional backlash of everything he does, slowly learning to let go while he continues to hurt her without understanding what he’s becoming. Over time, the imbalance shifts: she detaches, he unknowingly falls in love too late, and just as the truth begins to surface, she speaks the release vow. The bond breaks cleanly, but the magic enforces its final rule—she forgets the emotional depth entirely, while he is left remembering everything, including the moment he realized too late what he had destroyed.
