The aloof CEO Nangong Sihua has spent the first half of his life living as though everything were as fleeting as spring dreams and autumn clouds. But he suddenly realizes that all the glitz and glamour around him are illusory and impermanent. Just then, he unexpectedly welcomes an innocent and lively daughter, Qingli. Sweet and adorable, little Qingli gradually melts her father's long-silent heart with her purity and kindness, turning this detached young master, untouched by worldly concerns, into a devoted daughter-loving dad. Under her influence, Nangong Sihua and a group of his subordinates form a joyful, warm family. Together, they protect little Qingli as she grows, discover the true meaning of family affection and companionship, and embark on a new chapter in raising a child.
