"My older sister was dumped and her engagement broken off after being told that the true love of her life wouldn't be someone so ugly like her. I knew the younger sister was cuter anyway."

I am the older sister who was called ugly because of my glasses and freckles, while my younger sister had a cute face. People always said my younger sister was better off, and it was a pity for me as the older sister. Even our parents favored only my younger sister. Moreover, my younger sister would always say things like, "Big sister, what a pitiful face you have." And then finally, my fiancé, the Crown Prince, declared that he loved my younger sister and broke off our engagement because I was ugly. Well then, I am now prepared. I will have my revenge.
