The richest woman in the world, Laurencia Aztane, had success in both work and beauty, but her life was miserable. She worked day and night to protect the one and only family, her weak twins, Erusia. However, she discovered a cruel truth that the illness of her sister, Erusia, was a complete lie, and that she was cooperating with her fiancé to buy all of her property. At the moment Laurencia was forced to turn her back on her pain and remorse, she had gone back eleven years before her engagement. Her faith in Erusia, her affection for her fiancé; all of it could go to hell. Listen carefully, Sister, there is no good sister now. I pledge to redesign my life. The first thing is, I have to be tied up with a national hero whom the scumbag in the past cannot possibly deal with "I'll take care of the debt that you took unfairly. Instead, be my marriage partner, Grand Duke Verdian." (Source: Kakao, translated) Promotional one-shot of the novel of same name.
