It tells the story of Song Tinghuan, an AI genius girl who was forced to remain anonymous because her family went bankrupt and her project was stolen by her mentor. In order to pay off her debts, she applied to become the personal nanny of Shen Yuqing, the president of Shen Group. Shen Yuqing was disabled in both legs due to a car accident and had a cold personality, so he drove him away many times. Song Tinghuan relied on her intelligence to deal with Shen Yuqing's difficulties, and gradually swayed under Song Tinghuan's "AI style" care and tactful response.
