The night before her wedding, her world shattered.Betrayed by her own sister and abandoned by her fiancé, who demanded her kidney as the price for his love, she thought her life was over. But she refused to be a victim.At the altar, she made a bold move: she called off the wedding and declared she’d marry anyone willing to step up. To everyone’s shock, he—the richest and most powerful man in the city—stepped forward, claiming it was his “duty” to marry her.Overnight, she went from a betrayed bride to the wife of her ex-fiancé’s uncle, turning the tables on everyone who wronged her. From navigating family drama to outsmarting scheming rivals, she rose to become the undisputed queen of both families, building an empire of her own.Now, with a thriving career and a husband who adores her, she’s living her best life. But when her husband calls, begging her to come home because their twins are “starving for attention,” she knows her chaotic yet glorious life is just getting started.

He wants indoor plumbing. They think he’s conquering the world.Arthur was a genius engineer on Earth, capable of optimizing global logistics and automating entire factories.

The people of this world don't understand engineering.He builds a high-pressure boiler for a bath; his father thinks it’s a “Dragon-Breath Siege Weapon.”He creates a hydroponic garden; the local church declares him the God of Harvest.He ignores a Princess's flirting to analyze the thread count of her dress; she thinks he is playing “hard to get.”Follow Arthur as he accidentally industrializes a kingdom, terrifies his enemies with home appliances, and remains completely oblivious to the fact that he is becoming the most powerful man in history.All he wanted was a warm bath.
