She Leaves the Father but Keeps the Child, Only to Be Caught: The Heir Locks Her in His Bedchamber

[Substitute Bride + Villainess + Male Rivals + System Wage Slave + Husband's Regret + Turning a Difficult Mother-in-Law into a Grinning Fan]

Su Yue transmigrates into an ancient bridal chamber and is left completely bewildered.

She becomes a villainess, takes her sister's place as the bride of a lame general, and is forced to sign a contract of servitude?

Her husband is choking her, yet she has to rush into consummating the marriage. Fail to complete the childbearing task, and her life starts counting down?

A grandmother who looks down on her low status, a mother-in-law with a princess complex, a sister-in-law who despises her, and a younger brother-in-law who wants to become the heir.

Fortunately, Su Ran has a conquest System that provides her with intelligence at any time.

Her brother-in-law keeps a mistress outside and even wants to use a parasite spell on her husband. First, expose the mistress as a spy, then use the spell on the pair of them.

Her former fiancé has lost his memory and been disfigured. Help him recover his looks, then bring him under her sway!

The Second Prince of Chen has been reduced to a slave. Rescue him and, while she's at it, train the adorable puppy-like boy.

Together, they investigate cases, take on the worst sorts of people, and bring that powerful minister down.

After making it big, her useless man actually wants to marry another woman.

Su Yue decisively leaves the man but keeps the child. She used the System long ago to create a paradise of her own.

Only then does the aloof heir regret his choices, kneeling by her bedroom door every day to eavesdrop.

"My dear, I was wrong. Come home with me, will you?"

Su Yue rolls her eyes. "Hmph! You looked down on me. I won't forgive you!"
