When Bai Yue woke up, she found that she had actually time-traveled into the female supporting character with the same name in a certain novel. Although this character bore the title of a wealthy socialite in a prestigious family, her actual status was precarious. Without the support of a family background, her stepson treated her coldly, her biological daughter was so spoiled that she was timid and cowardly, and her tycoon husband was dead set on divorcing her. According to the development of the original plot, she would eventually be kicked out of the house, and then be exploited and drained by her parents and younger brother, ending up in a miserable situation. Thinking of all these, Bai Yue couldn't fall asleep the whole night. After tossing and turning, she finally made up her mind: Since she couldn't change the script of fate, she would take the initiative! She had to face the reality, play the role of "mother" well, and step by step, become a competent and professional worker in the wealthy family! Taking care of children? What's so difficult about that? She was a professional at dealing with adolescent problems! As for those members of her original family who were like bloodsuckers and tried to get close to her? Sorry, don't even think about it! Bai Yue firmly resisted any form of emotional manipulation (PUA). Even when she met a cheating playboy on the street, she would never show mercy and would definitely give him a good lesson. Unexpectedly, her efforts gradually changed everything around her. Her originally timid daughter, under her guidance, grew into a star baby sought after by everyone. Her cold stepson was also touched by her sincerity. Not only did his attitude change dramatically, but he also became her sweet love bodyguard. Even the classmates in the children's class affectionately called her "stepmom sister". Before she knew it, Bai Yue had transformed from an obscure and low-profile wealthy socialite into the invisible favorite of the group. However, as her reputation grew, envious eyes also followed, and rumors began to spread everywhere. Facing the escalating rumors, her tycoon husband, who had always been regarded as her "boss", suddenly took action. He spent a fortune to bid for a priceless piece of jewelry, just to set off her radiance. Bai Yue was stunned: Didn't they agree that she was just here to work and not to fall in love? Why did the plot suddenly take an unexpected turn?
