Mattheo Riddle and Y/N are Hogwarts’ worst-kept secret. They’re never officially together. Never officially over. Every few months, they have some explosive argument that ends with screaming across the common room, broken glasses at Slytherin parties, blocked owls, and promises that this time they’re done for good.

Because eventually Mattheo always walks back into the Slytherin common room looking irritated with himself… …and Y/N is already sitting in his usual chair with the smuggest smile imaginable. She never chases him. She doesn’t have to. She knows him better than anyone. She knows exactly which buttons to press, which memories to bring up, when to ignore him, when to look at him for half a
