She was once known for her powerful magic — the very reason she was chosen to be the crown prince's fiancée. But when a "saintess" appeared, fear of losing everything drove her to make desperate, reckless decisions. Accused of committing evil acts against the saintess, her engagement was broken off and she was exiled to a monastery. On her way into exile, she was ambushed by bandits... and killed.

But death wasn't the end. When she opened her eyes, she had gone back three years into the past! Yet her body was now frail, and her magical power had all but vanished. This time, she resolves to choose a different path — to pursue happiness, even if it means breaking off the engagement herself. The twist? The crown prince refuses to let her go! And even more shocking... a mysterious dark spirit, one never before seen in this world, chooses her as its master!
