Seolha Seon is the last of the Yul, a people said to have beauty passed down from divinity. After hearing the news that she was to be summoned to the emperor's bedchambers, Seolha's face was disfigured by her mother to deny him his prized concubine. Forced to endure years of abuse from those who ridiculed her, Seon's last hope for salvation is the emperor's twin brother, Muhon.
