Y/N and Mike Wheeler have always been known as the two people who cannot stand each other. From constant arguments during group plans to sarcastic remarks and competitive one-upping, their rivalry is practically legendary among the party. Whether it’s who comes up with the better idea or who gets the last word, neither of them ever backs down. But when a new threat forces everyone to work closer than ever, their usual fighting starts to shift. Late nights strategizing, moments of unexpected trust, and seeing each other in vulnerable situations begin to crack the walls they’ve built. Y/N starts to notice that Mike’s stubbornness comes from how deeply he cares, while Mike realizes Y/N’s sharp attitude hides courage and loyalty. As tension grows, so do their feelings—confusing, frustrating, and impossible to ignore. Jealousy creeps in when either of them gets close to someone else, and their arguments start to feel less like hate… and more like something neither of them wants to admit. In the middle of danger, when one of them is at risk, the truth finally surfaces: all that passion they’ve been using to fight each other was never really hatred—it was something much stronger. From sworn enemies to something neither of them expected, Y/N and Mike Wheeler find themselves falling for the one person they thought they’d never love.
