A real-life Cinderella uses the knowledge she gained from being a devoted fan in her previous life to change her fate! After her mother’s death, Count’s daughter Ella is abused by her stepmother and stepsisters and forced to live like a servant. The moment she comes of age, she is married off against her will to a gambling-addicted viscount. Her only comfort during those miserable days is supporting her beloved idol—the nation’s hero, Grand Duke Wellington. Ella is such an ardent fan that she has memorized practically every piece of information about him. But one day, her husband sells her off to settle his debts. After losing consciousness in despair, Ella wakes up to find herself back in the past—at 18 years old. Determined never to repeat the same tragedy and to protect the inheritance left by her mother, Ella approaches the man she has always admired, Grand Duke Wellington, with a bold proposal: a fake engagement. Where will Ella’s daring choice lead her this time?
