Nanfang, 25 years old, has completely settled down after graduating from college. She does not work, socialize, or fall in love, and lives a life of a home girl with black and white reversed. Under her persuasion, the 45-year-old parents decided to have a second child and gave birth to their younger brother Nanfeng. Since then, the South has been reduced to a "full-time tool for raising children."
In order to force their daughter to leave the house, Nan's father and Nan's mother arranged endless blind dates for her. In order to disturb the blind date, Nanfang always brought three-year-old Nanfeng to pretend to be his son, dressing up in weird ways, and it worked every time.
However, this time, she met her ex-boyfriend Jiang Zhixing, whom she broke up with four years ago.
Jiang Zhixing, 28 years old, is a well-known private equity partner. He has a successful career, is handsome and rich, but he is always single. Reunited four years later, he recognized the green-haired Nanfeng at a glance, and mistakenly thought that Nanfeng was the son she gave birth to for him.
A thrilling and hilarious reunion journey begins. And the biggest "assist" is the three-year-old little girl - Nanfeng.
