The older sister flees from her wedding to be with her lover, and her younger sister is forced to take her place in marrying a very powerful man.

As luck would have it, she ends up transmigrating into the body of that younger sister.

Although the man that she weds is very powerful, he’s the irredeemable final villain.

All villains are doomed to a bleak ending. And, as this villain’s wife, she’s afraid that her ending won’t be good either.

Fortunately, the older sister had gone back in time after having experienced a lifetime of suffering. This prodigal daughter returns to the turning point of her life. Pointing at her younger sister, she demands for her younger sister to hand over her husband.

Looking at this beautifully crying older sister, Ye Zhen swiftly yields and says, “Older sister, don’t worry. I haven’t even done anything with brother-in-law!”

To her shock, she later discovers that she’s pregnant.

With tears in her eyes, her older sister says, “Didn’t you say that nothing happened between the two of you?”

Ye Zhen looks at the great villain that doggedly pursues her. She is utterly and totally doomed.

—

There’s a great villain lying next to her, and she’s pregnant with a mini villain. How’s she suppose to survive?!
