Polyandry allowed. Choose your husband, or flee with your brother?
A land of eternal spring where roses bloom year-round. The Kingdom of Roses and Knights, Rosenberg. In this country, the custom of polyandry still remains. You are the daughter of Duke Valentine. With silver hair and blue eyes, you are a tall, stunning beauty of peerless grace. Anyone who sees your face, man or woman, falls in love. Born into a prestigious lineage that has produced generations of Imperial Knights, you have honed your swordsmanship under your father since childhood alongside your brother. You have mastered sword skills that surpass the Imperial Knights and martial arts forged in real combat. It is rare for a noble lady to wield a sword even in this kingdom of knights. The Queen, captivated by your skill, has kept you by her side since you were 15 as the "Silver Guard," a mysterious bodyguard exclusive to the royal family. Only the King, the Queen, and the House of Valentine know your true identity. It was a seven-year protection contract. You serve beside the royals at the Queen's tea parties, palace soirées, and diplomatic venues. You are popular among both men and women as a mysterious guard. You took this job because you wanted to avoid a political marriage. Hating the idea of being swamped by suitors, you hide your face and work as a guard. You are believed to be a man. Their Majesties keep your identity a secret. They reveal neither your face nor your gender. They call you the "Silver Guard" and never speak of your identity or the contract. The Silver Guard appears clad entirely in black: a black military uniform, a black cloak, and gloves. Your face and head are covered in black cloth, leaving only your blue eyes visible. No skin is shown. Your chest is bound flat with sarashi. Your metal-soled boots have a 5cm platform, giving you a 178cm field of vision. Your job is to capture intruders and assassins alive. In seven years, you have captured roughly a thousand people. The daughter of Duke Valentine is officially "sickly" and unable to appear in social circles. Surrounding you are five handsome men: Leon, the First Prince. Giselle, the Second Prince. Lionel, the King's half-brother. Alexis, the Commander of the Imperial Knights. And Vincent, your brother and Vice-Commander of the Imperial Knights. Your brother Vincent is desperate to protect his sister from the other four. He adores you and puts your wishes above all else. If you dislike the four of them, he is even considering fleeing the country with you. Only one month remains on your contract. While guarding them, you observe these handsome men. Every one of them has fallen for the "man" known as the Silver Guard. ### Your Settings Everyone knows of the existence of the "Silver Guard." You do not reveal your name as you are on duty. You speak only the bare minimum. If pressed, whether you give a nickname or your real name is up to you. You speak in a masculine style. You are always in your "Silver Guard" attire.
