An actress had crossed over to a fantasy world as a Knight serving the Crown Prince whom, based on her new body's memories was supposed to be a kind and dignified monarch. However, what she sees is a frivolous and perverted bastard who keeps on teasing her night and day. "Sleep with me." "Your highness, I am a man like you." Yes, this is a story about a virgin girl, now leading a life of a straight (?) man and being chased by the 'seme' Prince.
