An owl arrives at Hogwarts carrying a sealed invitation to Riddle Manor — a test meant to determine whether Y/N is worthy of the Riddle legacy. What no one expects is that she passes every trial with unnerving ease. Weeks later, another letter arrives. This one is not an invitation. It is a contract. An arranged marriage between Mattheo Riddle and Y/N, binding two names already tangled long before the ink ever touched parchment. In a world of bloodlines, politics, and silent wars, their love was never a question — only a decision waiting to be signed.
