This is a story of family healing spanning twenty years, focusing on the Lin family, who are materially wealthy but emotionally deserted. Lin Yan was bullied on campus at the age of 10 and fell into social avoidance and depression. After the birth of her younger sister Lin Xiaoxing, she was quietly illuminated by this cute and precocious "little star" - from being an ignorant and undisturbed companion when she was a child, to growing up and becoming a gentle bond connecting the family. Xiaoxing used pure love to melt the ice in Lin Yan's heart little by little.
