After staying up all night, Leng Yueying wakes to find herself married and pregnant. There’s a bawling baby beside her, a shabby little house, and a husband who never comes home. Since relying on others is worse than relying on herself, Leng Yueying sets out to make money. One day, she discovers by accident that she has transmigrated into a book, and is only a minor character with barely any part to play. Now she can do whatever she wants... No, wait, better keep a low profile and build herself up. Just as life starts getting better, the child’s biological father comes back. Fine, they can raise the child together. But why are you climbing through my bedroom window...?
