A down-on-her-luck young woman named Hollis disguises herself as a man to work as a personal attendant to Prince Asa of the Whitlock Empire, hoping to raise money for her adoptive mother's medical bills. Unaware that Hollis is a woman, Asa develops unexpected feelings for her, falls into fits of frantic jealousy, and becomes trapped in a spiral of self-doubt. As the neighboring kingdom's Prince Dash pursues Hollis aggressively, and the vicious villainess Delphine tries to steal her identity, Hollis’s long-buried childhood memories gradually resurface: she is Nura, the redemptive "white moonlight" Asa has been searching for desperately for years, and the true imperial princess. After a life-or-death experience in a fire and a final showdown at a wedding hearing, Asa publicly exposes Delphine’s plot, marries the real princess with deep affection, and the two embark on a fated romance.
