A Belated Noble Lady's Romance: Having Her Fiancé Stolen by Her Younger Sister ~ By Order of the Queen, I'm Going on a Date with the Knight Commander for Today ~

"Commander of the Isla Salud Knights. By order of Her Majesty the Queen, please go on a date with me for the entire day today." Isla was taken aback by the sudden proposal. Standing before him was Chloe Applegate, the Countess's daughter and lady-in-waiting favored by the Queen—27 years old. She was known as the "Ice Woman," a woman unmoved by men. However, her misandry was not without reason. Chloe had a past where her beautiful younger sister Lily had stolen her fiancé. The beautiful Knight Commander Isla, who harbored secret feelings for such a woman, gradually began to melt her frozen heart—but the appearance of Lily and her former fiancé completely ruined the atmosphere. However, he did not give up, and through a certain method, he captured her heart. This is a love story between two sisters and a somewhat devious Knight Commander who admires Chloe.
