After I Transmigrated and Took the Legitimate Daughter's Place as a Bride, I Became the Crown Prince's Beloved

[A transmigrated heroine takes on a reborn rival + Palace and household intrigue + Sweet romance + Both leads have no past relationships]

After a car accident, college student Ning Hua transmigrates into the body of Ning Hua, the eldest legitimate daughter of a duke's household.

Ning Hua lost her mother at birth. Her grandmother dotes on no one but herself, her father doesn't care about her, and her stepmother abuses her. Everyone in the capital knows she's an ill omen.

The crown prince falls gravely ill, and the emperor orders her to marry him to bring him good fortune.

Ning Qingqing, the legitimate second daughter who was supposed to enter the palace as the crown princess, has been reborn. Knowing the crown prince will soon die, she schemes to make Ning Hua marry the sickly prince.

Ning Qingqing plans to marry Prince Su, who will rise to great power in the future, and become his consort, then empress.

Ning Hua is ready to lie flat, too. Anything is better than staying home and getting beaten to death, even becoming a widow.

But how come the crown prince, who usually looks pale and delicate as a painting, as frail as a willow in the wind, is so full of energy at night?

Crown Prince: Hua'er, I'm not well.

Ning Hua: This... is what you call not well?
