/N and Ryan act like they can’t stand each other, constantly arguing, teasing, and getting under each other’s skin—Y/N thinks Ryan is annoying and full of himself, while Ryan thinks Y/N is stubborn and impossible, though he’s starting to notice her in ways he doesn’t understand. Ryan is best friends with Dylan, Y/N’s older brother, and they’re basically brothers, which makes everything complicated since Dylan is protective of Y/N and would never expect anything between them. Lily, Ryan’s best friend, is one of the few people who can tell there’s more going on between him and Y/N than either of them will admit. When Dylan plans a two-week road trip with no parents, Y/N and Ryan are forced to spend more time together than ever, turning their usual arguments into something that slowly starts to change.
