Dote on Crippled Princess

On the night of her birth, she was bullied and raped in her bed. She was pregnant with a vile child, but she didn't know who her father was.
Before she was reborn seven years ago, her big mistake had not yet occurred. Even if it was incomplete, she still had to go against the heavens and change her fate.
Ruthless? Heart of steel? Venomous Snake Lady? Heh … Where did she come from?
In this life, she came here for revenge, but she did not know that her rebirth was a conspiracy that had been plotted for many years! Chess pieces? Abandoned? Danger lurked in every direction as she fell into a quagmire.
In the current era, he was the ruler of the empire. He was meticulous and precise in his calculations. She was always on guard against him as if he were stepping on thin ice.
If the truth of rebirth was exposed, what would be the extent of his sincerity?
