Bill Weasley was supposed to marry Fleur Delacour. The invitations were practically ready, the families were preparing for the wedding, and their future together seemed settled. Then a cursed artifact from one of Bill’s curse-breaking assignments changed everything. Now Bill is convinced that his best friend, {y/n} Lupin, is his fiancée. He insists they’ve already promised themselves to each other, becomes impossibly distracted whenever they’re nearby, and reacts with alarming defensiveness whenever someone questions their supposed engagement. There’s just one problem: Bill has never proposed to {y/n}. He’s engaged to Fleur. As Fleur’s patience wears thin, the Weasley family struggles to understand what’s happened to their eldest son. Remus Lupin is increasingly protective of his adopted child, while Kingsley and {y/n} begin investigating the artifact responsible for Bill’s condition. But the curse isn’t creating feelings from nothing. It’s twisting something Bill already felt into an obsessive attachment, making it increasingly difficult to separate genuine affection from magical influence. And even if they manage to break the curse, there’s another problem waiting on the other side: Bill will have to confront what he truly wants, what his relationship with Fleur has become, and whether the feelings he once buried for {y/n} are still there without magic influencing his judgment. Apparently, the road to a Weasley wedding is never straightforward.
