Mia es la princesa del Imperio Tearmoon, y tras una vida de lujos y despreocupaciones, cuando una rebelión derroca a la familia imperial, ella acaba pasando varios años en un calabozo hasta que llega el día de que la pongan bajo la guillotina. Por suerte para ella, Mia no muere, sino que vuelve a su cuerpo de ocho años atrás, cuando tenía 12 años. ¿Fue solo un sueño o pasó de verdad?

Mia necesita poner a Ludwig de su parte para intentar solventar los problemas económicos del reino y evitar que ella acabe en la guillotina, pero ¿Cómo logrará que el joven funcionario la ayude?

Mia comienza su vida en la Academia Saint Noel con dos simples propósitos: no relacionarse con las dos personas que en su anterior vida la llevaron a la guillotina, y hacer contactos que le puedan ser útiles en caso de una posible revolución. Por supuesto, los planes no siempre salen bien.

Llega el día del baile y Mia acude con Abel, quien sigue sin terminar de creer que la princesa del Imperio Tearmoon lo eligiera a él como pareja.

Ever vigilant to find new means of self-preservation, Princess Mia joins the equestrian club. As the academy's sword fighting tournament approaches, Mia finds herself wrapped up in a student tradition. She needs all the help she can get with it.

Keithwood rushes to prevent Mia, Chloe, Tiona, and their attendants from ruining lunch with their blatant incompetence. Then, as the tournament approaches, Prince Abel finds himself facing opponents he's desperate to overcome to prove his worth.

Back home during a school break, Mia refocuses her efforts on the Tearmoon Empire's issues within its borders. She uses her school connections to procure resources and does everything in her power to avoid an upcoming conflict.

Princess Mia returns to the forest with Dion to recover her hairpin and finds herself thrust into negotiations with the chief of the Lulus. Afterwards, she takes steps to properly secure the support of the Ruldovon family.

Princess Mia's excitement to be back at Saint Noel Academy is cut short when word of a revolution in the Kingdom of Remno reaches her and her classmates. Concerned for Prince Abel, Mia and her friends plan to sneak into Remno to look for him.

As Princess Mia and Prince Sion move to rendezvous with their friends, Mia is kidnapped and separated from her last ally. While in revolutionary custody, she'll find a new ally and learn that things may not be as they seem with Remno's rebels.

Mia and Sion finally reunite with Prince Abel. However, the circumstances are far from happy as Sion quickly challenges Abel to a duel for his loyalty to an oppressive royal authority! Will Mia's pleas be enough to prevent bloodshed?
