Li Zhi transmigrates into a period novel as the real daughter. As the foil to the original heroine's adored fake daughter, she's despised by everyone and gives birth to twins, a boy and a girl.
The children's father has eyes only for the fake daughter, his first love, and treats Li Zhi with icy indifference. "Where did these bastards come from? Don't expect me to acknowledge them!"
Li Zhi: ...Fine. Divorce, and I'll live my best life!
Later, Li Zhi makes tons of money, buys tons of houses, and finds another man to be by her side.
Her cold, aloof ex goes mad and pins her tightly in his arms, eyes bloodshot. "You want my children calling someone else Dad?"
"The children are mine. That has nothing to do with you."
"No, they're my biological children!"
