Abused by her stepmother and stepsisters following her mother’s death, Count’s daughter Ella spends her days treated like a lowly servant. Upon reaching adulthood, she is forced into a marriage with a gambling-addicted Viscount. Her sole comfort in this miserable existence is her fanatic devotion to the nation’s legendary hero, Grand Duke Wellington, memorizing every single detail about him. When her husband sells her off to settle his debts, Ella loses consciousness in total despair, only to awaken back in the past at eighteen years old. Determined to escape her tragic fate and protect her mother’s inheritance, Ella uses her ultimate fan knowledge to propose a strategic fake engagement directly to the Grand Duke himself.
