Nobody at Hogwarts expected the transfer student to survive Mattheo Riddle’s attention. Cold, possessive, and dangerously obsessive, Mattheo is the kind of person people fear in whispers — a Slytherin prince wrapped in cigarette smoke, bruised knuckles, and violent devotion. He doesn’t get attached. He doesn’t lose control. Until her. What begins as curiosity quickly spirals into something darker: lingering stares across the Great Hall, jealous tension, whispered threats, possessive touches, and an obsession neither of them can stop feeding. Because the more the transfer student challenges him, the worse Mattheo becomes. Protective before affectionate. Possessive before honest. Obsessed before romantic. And at Hogwarts, being wanted by Mattheo Riddle may be the most dangerous thing of all.
