A commoner, the illegitimate child of a bard. Leone, who has no background to boast about, gained power as a maid thanks to her extraordinary intelligence. However, when the empire she thought would be immortal, collapsed due to an enemy invasion, she met her death at the hands of the enemy's sword. Her life was marked by a willingness to harm others and use trickery because of her greed. A life full of regrets made death feel pleasant, but... she returned.
She went back to the time when she had just entered the palace as a maid. This was clearly a chance to correct the mistakes of her previous life. "This time, I will not live a life of harming and taking from others, but a life of protecting and nurturing." So, she chose the crown prince—her political enemy whom she had dethroned with her own hands in her previous life—as the key to changing her fate. She assisted him as a maid, and everything seemed to be going well...
"Leone, let's leave this place together."
Something seemed wrong. The secrets of the crown prince, thought to be cold and indifferent, and the truth hidden from the world began to unravel, and the shadow of destruction loomed over the empire.
