Demoted from Wife to Concubine? The Legitimate Daughter Turns Around and Marries into the Palace as Empress

[Mad, reborn male lead + female lead who transmigrates into a book and pretends to be a naive sweetheart + devoted to each other + career-focused couple + household and palace intrigue + clear-eyed heroine + young emperor and empress]

Ji Yaorao transmigrates into the male-oriented novel The Struggle for the World as a villainous supporting character. She is supposed to marry the male lead, but on their wedding day, her half-sister takes her place. The original Ji Yaorao, madly in love, willingly enters the household as a concubine, only to die taking a sword meant for the male lead.

To defy fate, Ji Yaorao instead marries the governor, Nangong Jiayan. When she discovers that her husband is the villainous emperor, she decides they should work together, and the two become partners with a shared interest.

Nangong Jiayan becomes emperor, and she becomes empress!

In his previous life, Nangong Jiayan was a career-driven second male lead who fought the male lead all his life. Though he ultimately won and ascended the throne, he sat alone upon it until his death, never taking a wife or a concubine.

The arrival of Ji Yaorao, who transmigrated into the book, rewrites his ending. He thought he was the one moving the pieces, but never expected to fall for her more deeply with every passing day.
