Lady Cinderella

After her mother's death, Elladis (Ella) had fallen from her father's favor and was reduced to being a maid under the abuse of her stepmother and sisters. But her stepmother wasn't satisfied to treat Ella as her maid, so she forced her to marry a gambler-crazy Viscount. The only pleasure for Ella, who lives a difficult life, was the country's hero, Archduke Wellington. She goes through each day memorizing anything about Archduke Wellington. The Viscount, who is her husband only in name, sells Ella to pay his gambling debts. However, Ella, who runs away with the intention of dying, somehow returns to the age of 18 after a desperate wish. The opportunity came once again like a miracle! She decided not to live the way she used to until she inherited her mother's legacy and chose to entrust herself to Archduke Wellington. What will be the conclusion of Ella's bold choice, who proposes a contractual engagement to Archduke Wellington using the information she knows from her previous life as bait?
