Back to the 1970s: Commander Shen, Hurry and Take Your Wife Home

After returning from the apocalypse, Xia Yilin learned that the world she lived in was a book and that she was an insignificant background character. She immediately set three goals.

First, split from the family and stop working like a beast of burden for her scumbag father and stepmother's family.

Second, reunite with her relatives: find the Chu family, who had been sent away, protect them from harm, and enjoy the good life with them once they were cleared of their charges.

Third, save the book's main villain, become the biggest obstacle for the hero and heroine, and keep making trouble for them.

But why does that big villain keep clinging to her?

Xia Yilin: Hey! You're the big villain. You should be going after the hero and heroine, so why are you clinging to me?

Shen Dongliang: Honey, I'll go in a bit. Let me cling to you a little longer, okay?

P.S. The male lead appears fairly late. Don't read if that bothers you.
