Mia gets a second chance and immediately chooses to be selfish anyway, except this time her selfishness saves everyone. The diary is a weapon, not a redemption arc, she's reading the future like a cheat sheet and weaponizing her own narcissism to rebuild an empire. Every good thing that happens is a side effect of her trying to live a comfortable life, and the show never makes you choose between rooting for her ambition and watching her accidentally become the leader everyone needed.

Princess Mia of the Tearmoon Empire, known as the selfish princess, is sent to the guillotine after a revolution topples her failing nation. Then she wakes up as her twelve-year-old self, with the bloodstained diary from that doomed future lying beside her pillow and every memory of what went wrong still intact. Determined to avoid her original fate, Mia sets out to rebuild the empire. The motivation isn't noble ideals or compassion for her people, though. She is driven purely by the wish to keep her neck away from the blade. Using what she knows of the future, she works to fix the empire's troubles and gather allies, and her self-serving efforts end up winning the hearts of the people, who come to see her as a saint. Based on a light novel series, this comedic fantasy with touches of drama and romance follows a cowardly, self-interested girl racing to change history before it repeats itself.
