Y/N wakes in St. Mungo’s Hospital with no memory—no past, no allegiances, no understanding of who they once were. The world is a blank slate, and every face is unfamiliar… except one. Tom Riddle. He arrives composed, controlled, and entirely prepared. And when Y/N looks at him with confusion instead of defiance, he doesn’t hesitate. “I’m your boyfriend,” he says smoothly, as if it has always been true. “Don’t you remember?” With no memories to contradict him, Y/N has no choice but to accept the version of reality he offers. Under his careful guidance, their former rivalry is rewritten into something softer, closer—something binding. But fragments of the past don’t stay buried forever. As fleeting instincts, misplaced distrust, and echoes of a former self begin to surface, cracks form in the story Tom has constructed. And the question becomes far more dangerous than simple truth or deception— If Y/N remembers who they really are… will they become his greatest ally— Or his most devastating enemy?
