Jasmine Gould has fallen for Mattheo Riddle. Unfortunately, so has his girlfriend. Or at least, that’s what Jasmine thinks. Y/N Riddle is always touching him, stealing his clothes, sitting in his lap, playing with his hair, and acting like the two of them are completely inseparable. And then there’s Theodore Nott—the boyfriend Y/N is supposedly cheating on. Jasmine is convinced she’s uncovered the most scandalous love triangle at Hogwarts. There’s just one tiny problem: Y/N isn’t Mattheo’s girlfriend. She’s his twin sister. Now Jasmine is determined to expose Y/N’s “affair,” while the Slytherin friend group watches in increasingly horrified amusement as she turns eighteen years of completely innocent sibling behavior into the scandal of the century.
