Sixteen-year-old {y/n} Riddle has no interest in saving the past—they want to use it. As Mattheo Riddle’s future child, {y/n} deliberately travels back to their father’s teenage years with a sinister plan already in motion. When the Slytherins return from classes and find an unfamiliar teenager standing in the middle of their household, they immediately notice the impossible resemblance between {y/n} and Mattheo. {y/n} knows exactly who they are, knows secrets they shouldn’t know, and seems completely unfazed by their suspicion. But Mattheo has no idea that the mysterious teenager standing before him is his future child—or that {y/n} has come back to manipulate his world for their own dark purposes.
