Secret Agent Crazy Concubine: the Absolutely Pampered, Stupid Fifth Miss

She is the fifth daughter of the regent's palace, but she is stupid and stupid, and is despised by everyone. She is an ace agent from another world, with a cold and ruthless personality, feared by everyone. One expressed love on the street and was beaten to death by a scumbag, while the other was betrayed by his friend and died accidentally due to a conspiracy. When the weak and stupid identity merges into the strong and cold-blooded soul, the color of the world changes. Although he is a sick and weak prince who is not taken seriously, secretly he controls the terrifying secret palace. He wears a mask all year round, endures humiliation and carries heavy burdens, and plans great achievements. But her appearance became the biggest variable in his plan. Finally, she asked him coldly: "Do you want me, or do you want the country?" His eyes were firm: "You, I want it. I will give you the country."
