Years ago, a misunderstanding tragically separated Ye Chen and Su Nian, cutting off all contact between them. Su Nian gave birth to twins, Huanhuan and Lele, on her own and entrusted them to their great-aunt in the countryside. Years later, when their great-aunt's health began to deteriorate, she arranged for the children to travel to their biological father's home to find him. The two little ones knocked on Ye Chen's door, and their sudden appearance and claim of being his children caught the single man completely off guard. After a paternity test confirmed their blood relationship, Ye Chen officially accepted the girls as his daughters. From then on, he devoted himself to his work while lovingly caring for the children, gradually unraveling the many misunderstandings that had separated him and Su Nian years ago.
