Plot Summary: Jiang Yiran transmigrates into a melodramatic novel as the villainous stepmother. The original host, mistakenly believing the triplets to be her husband's illegitimate children, abused them and was ultimately killed by her vengeful stepson after his dark transformation. Armed with knowledge of the plot, Jiang urgently pivots from this self-destructive path: she nurses Lu Xingxing through a dangerous fever, prevents Lu Yebai's fatal fall, and gradually wins over the three adorable children. Meanwhile, Su Muqing - the novel's original time-traveling heroine - attempts to follow the established storyline to replace Jiang, only to discover the narrative has derailed.
