Three-year-old Youyou sells goods at the night market with her mother until her biological father, Shen Yue Bai, brings her back to the Shen family. With her childish words and sincere heart, she awkwardly tries to get close to her cold-faced dad, comforts her lonely cousin with hugs, and draws, raises a cat, and makes friends under her family's protection. Shen Yue Bai gradually learns to be a father, going from a helpless novice to someone who crouches down to listen to his daughter. The Shen family also grows close again because of this little girl. Youyou never fights for attention or competes with anyone; simply by being there, she becomes the apple of the whole family's eye.
