The Genius Doctor's Rebirth 22

Dorothy, a genius physician from the 21st century, found herself transported back in time, becoming a woman deemed unattractive. After being doubly betrayed by her scummy fiancé, Crown Prince Carl, and her scheming sister, Kristine, she boldly broke off the engagement on the spot. She publicly confronted the deceitful pair and then turned to marry the powerful Ninth Prince, Ethan. The couple joined forces, and ultimately, Ethan ascended the throne as Emperor with Dorothy as his Empress. They remained devoted solely to each other for life.
