Source: Seven Seas Entertainment, Vol. 1 A woman who’s lived her life in the shadow of her sister must suddenly take her place after a tragic accident—but her life is about to get way more complicated. Marie was never meant to shine. Though she’s a baron’s daughter, she’s treated like a servant in her own home—especially compared to her glamorous sister, Anastasia. Even on Marie’s birthday, the spotlight is stolen, as the family uses the party to parade Anastasia before potential suitors. But when the dashing Count Kyros accidentally stumbles upon Marie—ragged clothes and all—he’s instantly taken with her. Sparks fly… until a mix-up leads him to propose to the wrong sister! Can Marie and Kyros overcome the confusion and find their way back to each other?
