A modern, spirited postdoc unexpectedly transmigrates into a book, becoming Valeria, a 200-pound princess despised by Prince Sebastian and framed by her cousin Mia. Right after arriving, she finds herself falsely accused of having an affair. Using her modern mindset and determination, she breaks free from dead ends, exposes fake friends, confronts the scummy prince, creates a refrigerator to make money and solve her living difficulties, sets a weight-loss goal, and begins her transformation. Amid doubts, exclusion, and scheming, Valeria proves her worth, impresses the palace with her intelligence and skills, earning the queen's respect, and gradually wins the heart of the scummy prince. Through it all, she stays true to herself, focuses on building her career and improving herself, and moves toward success and independence, writing the legendary comeback story of a once-overweight princess.
