Her obsession with little boys has become a significant aspect of her life, despite her reluctance to admit that she is a pervert. Her friends are well aware of her shota-con tendencies. Ahiru has always dreamed of marrying a young prince, and her fantasy appears to become a reality when a new student, Shirayuki, transfers to her school. However, the following day, supernatural events occur, and Ahiru finds herself in an alternate dimension with a fever. When she enters the infirmary, she sees Shirayuki sitting on a throne and is informed that she will be the wife of the prince of the Devil's world. What in the world is going on here?
