Flirting Mistake: I Married My Ex's Billionaire Uncle Overnight Novel

Nina Sinclair's boyfriend of three years is marrying someone else and has the audacity to invite her to the wedding. Furious, she hires a man to pose as her husband—specifically impersonating her ex's mysterious billionaire uncle—to humiliate the couple at the event. However, the marriage certificate turns out to be genuine, and her fake husband becomes her real one, demanding she fulfill her marital duties. To shame her cheating ex, Nina accepts the situation. Her hastily chosen husband proves exceptional: wealthy, devoted, and eager to help her exact revenge on the scumbags while doting on her relentlessly. Things grow stranger when Nina notices her husband vanishes whenever the billionaire travels, and a rare pink diamond necklace photographed with the billionaire mysteriously appears on her dresser. The truth becomes undeniable: her bargain husband is the billionaire himself. Confronting him, he simply pulls her close and whispers, "Stay calm, my dear wife. Don't let this stress affect our baby."
