In the modern city of 2024, top actor Lin Mo unexpectedly became the single dad of his daughter "Little Rice Cake" at the peak of his career. This "drama star" with a cold appearance and superb acting skills is a well-spoken "Brother Mo" on the set, but when he returns home, he has to face the chaos of being slapped in the face by baby wipes when changing diapers, having his daughter play "on-demand" children's songs out of tune when putting him to sleep, and being counterattacked by "little rice cakes" with a spoon during complementary feeding time. In order to balance career and family, Lin Mo reached a cooperation with gold medal agent Su Qing. Su Qing used her professional skills to help him screen scripts and deal with paparazzi, while Lin Mo provided "cross-border" advice when Su Qing was stumped by parenting problems. During this period, Lin Mo's "daily life as a nanny" was accidentally photographed by fans and posted online, triggering the topic of "top movie stars contrasting cuteness"; rival Zhao Yu tried to suppress him by using rumors of "having a daughter out of wedlock", but Lin Mo cleverly resolved it with cute photos of his daughter; assistant Xiao Xia grew from a novice in the workplace to a "little expert in raising children" under Lin Mo's "special parenting training". In the end, with the help of Su Qing and Xiao Xia, Lin Mo not only successfully completed the filming of the movie, but also revealed the existence of his daughter at the premiere, receiving blessings from the entire network and achieving the dual perfection of career and family.
