Over the last year, Mattheo Riddle has made it his mission to tease Y/N for being a weak Hufflepuff. It had been harmless, for the most part, but one day he takes it too far. While she is studying in the courtyard, he snatched her textbook from her and held it above her head, embarrassing her in front of half their class. Having had enough of his bullshit, Y/N finally stops being the bigger person. Unfortunately for her, that only delights him. He won’t be leaving her alone any time soon.
