There’s a villain in every novel. Elfie, who reincarnated to a novel as the maid of the future villain Prince Tron, thought. Wouldn’t a happy future come if our prince becomes nice? However, the ending that came for Tron, who grew up as a good person, was only as a corpse as he got caught up in a fight. Elfie wails as she regrets her own choice. When she came to her senses again, an unexpected sight was unfolding before her eyes. She returned to the time when she first met 12-year-old Tron. To save Tron and give him happiness, Elfie wants to make him a king by fully mobilizing all the knowledge of the future she knows. With that, she determined to raise the prince, who is still young and kind. “Okay. Then, let’s look forward to seeing how much that swindler looking maid will please me.” But, is it really the best way to raise that prince as a good person?
