After giving birth to her daughter, Wen Ying unexpectedly gains the ability to understand babies' inner thoughts. To secure a Beijing household registration for her daughter, she applies alone for a nanny position with the Shang family. She easily handles triplets whom even a PhD-qualified nanny cannot manage. She tears apart a manipulative live-in son-in-law's schemes and saves a powerful businesswoman suffering from postpartum depression. Even Shang Jue, the Shang family's second young master, who is naturally suspicious and believes she is trying to climb the social ladder, comes to willingly protect her after the truth repeatedly comes to light. "No one is allowed to lay a finger on this woman!" Her former in-laws, who once looked down on her, regret their actions bitterly. By then, a long queue forms outside the Shang residence as people arrive carrying their babies and shouting, "Wen Ying, come work for my family!"
