The Shaderan household, once powerful but now teetering on the edge of financial ruin, is desperate to regain its former status. The selfish baron and baroness shower their beautiful elder daughter, Anastasia, with attention in hopes of securing a wealthy marriage alliance, while treating their younger daughter, Marie, with the scorn typically reserved for a lowly servant. Years of neglect and abuse have left Marie convinced that she is unworthy of love or kindness.
At a celebration held to showcase Anastasia, Marie encounters Count Kyros Granado. He is immediately captivated by her and her knowledge of his family history. Mistaking Marie for Anastasia, Kyros proposes marriage. Tragically, Anastasia dies in an accident before the wedding can take place. Reluctantly stepping into her sister's role, Marie becomes Kyros's betrothed—assuming the position he originally intended for Anastasia. Despite Marie's deep insecurity, Kyros remains unwavering in his support, helping her recognize her own worth and discover true love.
