Wu Zhaoping used to think the empress was the most honored person in the world, yet even she couldn't escape the fall of her kingdom and the ruin of her family. Her fate had always been in someone else's hands.
Given another chance, she wants to take control of her own life. In her previous life, she used many people for power and money, and wronged plenty of them.
This time, she won't go looking for trouble, but trouble finds her anyway. The young marquis inexplicably hates her, and her fiancé, who should have died, has become a prince of an enemy nation.
(It's a brainless feel-good power fantasy, so don't overthink the logic.)
