Due to her high magical powers, Rachel became the fiancée of the crown prince, but was afraid that the appearance of a saint would deprive her of her position.
His engagement is annulled and he goes to a monastery for committing a treasonous act towards the saint.
However, they are attacked by bandits on the way to the monastery. When Rachelle, who thought he was dead, wakes up, he has gone back in time three years ago.
However, his high magical power was almost gone, and instead he became so sickly that he could not get out of bed.
Luckily, this time I tried to cancel the engagement, but for some reason the crown prince refused! ?
