In the coastal city of Ningzhou, Su Wan's dream of buying a house was shattered by her parents who favored sons over daughters. The down payment of 150,000 yuan, which she had saved for three years, was secretly transferred to her younger brother for a wedding house. In a desperate situation, she used her many years of childcare experience to become a confinement nanny and broke into the wealthy life of the cold-blooded CEO Lu Chengyuan.
Faced with Lu Chengyuan's doubts about being "young and inexperienced", Su Wan used her expertise to break the prejudice: soothing Nian An, the young master of the Lu family who suffered from colic, and counseling Mrs. Lu Lin Man, who suffered from postpartum depression, and even won the recognition of the wealthy old lady and the sincere treatment of his daughter Lu Xingyao. However, she was driven away by Lu Chengyuan due to a misunderstanding, leaving Lu Zhai in chaos and Nian An missing her.
When Lu Chengyuan clumsily regretted it on a rainy night in the old city, when the two worked together to prepare their 40-square-meter loft, and when the reconciliation of the native family was intertwined with the acceptance of the wealthy family, Su Wan finally understood: home is never a cold house, but a gentle haven with Lu Chengyuan's protection, Nian An's dependence, and the warm sunshine in the room.
