Story Overview
One day, Julianne, the Marquess’s daughter, suddenly remembered her past life. Looking back, she realized how selfish and cruel she had been—living in luxury, tormenting her siblings, and obsessively following her fiancé. Her personality mirrored the villainess of the novel she once read, and her appearance reflected years of indulgence. Determined to change her fate, Julianne decided that if misfortune was inevitable, she would face it with a transformed body and soul. With renewed resolve, she embarked on a journey of dieting and self-improvement, dedicating herself wholeheartedly to her family along the way.
