Y/n and Mattheo Riddle have hated each other for years. Nobody remembers why anymore. So when a game of spin the bottle forces them to kiss at a Slytherin party, it’s supposed to be nothing more than an embarrassing joke. Except neither of them can stop thinking about it. Weeks turn into months. The arguments continue. The insults continue. The hatred continues. But now every glance lasts too long. Every accidental touch feels intentional. And every argument ends with them wondering if maybe they don’t hate each other as much as they’d like to pretend. The worst part? The first kiss was an accident. The second one definitely wasn’t.
