In his previous life, the talented director Gu Yan was ruined due to the disastrous failure of a movie. He was abandoned by capital and misunderstood by his first love Lin Wanqing. He eventually died of illness in poverty. Three months before he returned to the film project, he vowed to change his destiny, but unexpectedly picked up a cute five-year-old Su Nuannuan on the set who claimed to be the daughter of an investor. Su Nuannuan held up a tablet to broadcast live, and in a coquettish voice, she appointed him to film "Mom and Dad's Marriage War" and asked actress Lin Wanqing by name to play the female lead.
