At the collapsed Tearmoon Empire, 20-year-old Princess Mia Luna Tearmoon, who was scorned as a selfish princess, was executed through guillotine. However, instead of dying, she awakens to find herself back in her 12-year-old body, initially believing the event to be dream, before finding her diary covered in her blood from the execution and containing the entries she made prior to the event. Pleading to avoid the execution at all cost, she decides to rebuild the empire. As such, she would "put her own safety first". Her supposedly selfish action, mixed with her knowledge from her first life, somehow charms the people around her instead as she works hard to turn her enemies in her first life to be her allies.
