I Transmigrated Into a Book and Became the Factory Director’s Darling

[Period setting + wealthy family + marriage first, love later + raising villainous kids] Zuo Li transmigrates into the role of the cruel stepmother of four villains. To stay alive, she decides to cling to her factory-director husband's coattails. When he comes home late at night, she greets him eagerly: “Welcome home, Mr. Gu.” But her husband isn't there. Instead, the villains appear. The eldest gives her a cold, stern look, proud and aloof. The second seems gentle on the surface, but inside he's full of resentment: “Stepmother?” The third wears a brazen smile and speaks with malice: “Second Brother, she's the little stepmother!” And the fourth looks like an angel but acts all sweet and innocent: “Auntie Zuo, why did you push me? It hurts~” Zuo Li trembles and clings to her husband. “Help me, honey! There's something wrong with your kids!”
