At the Hogwarts masquerade, Y/N meets a masked boy who is sharp, arrogant, charming, and impossible to walk away from. Neither of them gives a name. Neither of them realizes they already know each other. By daylight, he is Mattheo Riddle: Slytherin trouble, Y/N’s enemy, and the boy you reported months ago after finding him in a bloodied, ruined corridor. Y/N thinks she saw the truth. Mattheo knows you never did. Now they are both haunted by a stranger from the ball while tearing each other apart in the corridors, never realizing the person they want is the same person they hate.
