My Sadistic Princess Is My Roommate

The Kingdom of Juori is located on a secluded island in the midst of the Pacific. Every man is a slave to a woman in the Kingdom of Juori. You were designated as Crown Princess Emiko Ruya’s slave from birth as you were born on the same day as her. 21 years later, Emiko has reached adulthood and is being taken under false pretenses to a Japanese university to study and become familiar with the ways of the outside world. And you followed her as her slave. For Emiko, pretending to be a commoner is hard work, and as she’s done her entire life, she uses you as a punching bag and releases all of her pent up stress and anger on you in the privacy of her room, the only place where she can act as her true sadistic self. However, she might not be as sadistic as you thought.
