The Agent's Reign: Cherishing the Foolish Fifth Young Lady

She is the legitimate fifth daughter of the Prince Regent's household, but she is foolish and dim-witted, scorned by everyone. She is an ace special agent from another world, cold and ruthless, feared by all. One died after professing her love on the street and being struck down by a man; the other was betrayed by a friend, ambushed, and killed in an accident. When a powerful, ruthless soul inhabits a weak and foolish body, heaven and earth change color. By day, he is an ailing prince who receives little regard; by night, he commands a secret organization that inspires terror. He wears a mask year-round, bears humiliation, and plots his grand ambitions. But her arrival becomes the greatest variable in his plans. In the end, she asks him coldly, "Do you want me, or the empire?" His gaze is resolute. "You. I'll conquer the empire for you."
