A secret that I, a maid of the imperial palace, accidentally heard… that the runaway fiancée of the prince was actually a man?! *"Please spare my life! I'll do anything!"* *"Anything?"* As I desperately nodded my head, the prince gave a chilling smile. There's only one way to not get silenced permanently! *"Then I choose you."* *"For what?"* *"To be my fiancée."* To become the fiancée (replacement) of the prince.
