Crossing books to become a vicious stepmother, Jin Xi decides to turn over a new leaf. The second male lead Zhou Yanqian, whom she abused in the novel, will grow up to become a dark villain, but right now he is only a three-year-old milk baby. To prevent the tragedy from repeating itself, Jin Xi opens her pet-the-cub mode: feeding, coaxing to sleep, buying clothes, and protecting the cub, stubbornly raising the future major villain into a soft and cute little milk bundle. But Zan Zan is full of vigilance: why has the bad woman suddenly become gentle? Faced with wicked servants making things difficult and relatives acting up, the kung-fu stepmother meets every trick with ease. As the little villain is warmed up little by little, this family begins to quietly change.
