A woman who was living an ordinary life suddenly wakes up inside a TV show as a cruel nanny who is destined to be killed by the twin princes she mistreats in the future.

Knowing the tragic ending that awaits her, she decides to completely change the story. Instead of abusing the young princes, she works hard to raise them into kind and responsible adults before they become corrupted.

Things seem to be going well at first, but her peaceful plan becomes complicated when a powerful and feared duke starts taking an interest in her. As she grows closer to the royal family, her new life becomes filled with unexpected relationships, danger, and romance.
