Sorry Big Sis, But I’m Stealing the Crown and Your First Love!

Duke Luna Iris' daughter fell in love with the crown prince when she first met him in the garden at night. However, taking advantage of their indistinguishable resemblance, her older sister Rosa came forward and said that it was she who had spoken to the crown prince. Rosa successfully got engaged to the crown prince. But Luna's first love was taken away by her older sister, who has always wanted what she had. Luna saw her sister off to the royal palace. You would think that she would be crying in secret, having had her first love broken. --Hehe... so far so good! They don't just look alike. This is the story of a sly younger sister getting revenge on her sly older sister who wants everything.
