Kurt is the crown prince of the Kingdom of Ast, and the only child of the King but was forced to go on the run when the nation is invaded by an antagonistic empire. Kurt lives with a secret known to only her closest allies. Though she is presented as a man, she was born a girl. Due to the rules of royal succession in Ast, only male heirs are allowed to claim the throne, but Kurt has no siblings, and the act of a female heir openly claiming the throne would instigate a political incident. Thus, Kurt lives publicly as male in order to maintain position as the royal heir. Kurt's fiancée, Princess Rose of the neighboring kingdom of Holtz, is fully aware of this truth, but it has no impact on her love for her.
