At the birthday banquet, a cup of poisoned wine sent Princess Tang Zan to her death.
When she opened her eyes again, she had become Li Shengming, the regent who held the court in the palm of his hand!
A man's body, an emperor's soul; a woman's body, imprisoned in the palace.
Her body became a sacrifice for a political marriage, while his power fell under her command.
A bloodstained imperial seal, a web of old cases, and the bloody palace coup from ten years ago all lead to a shocking secret.
Could the young man who once saved her life be the sworn enemy with whom her soul is now out of place?
Two souls trapped in the wrong bodies are forced to join hands, stirring up the realm under each other's identities.
When identity is both a shackle and a blade, can they defy fate and reclaim control of the world?
Theme: Identity is only an outward appearance; our choices define us. Protecting our homeland and those we love matters most.
