Lin Bei has always followed his childhood friend, Zhao Yang, like a trend. When Zhao Yang gets divorced, Lin Bei impulsively proposes a divorce of his own. His wife, Su Nian, readily agrees, making him suspicious. After investigating, Lin Bei discovers that Su Nian has secretly transferred 3.8 million yuan to her ex-boyfriend, Zhou Kai, over the past four years. Lin Bei quietly gathers evidence and prepares to deal with Su Nian's schemes, including pretending to be pregnant, planting an informant, and attempting to transfer the proceeds from their house. In court, Su Nian's side forges an IOU and bribes witnesses to give false testimony, but their tricks are dismantled by an airtight chain of evidence. The court grants the divorce and divides the marital assets in a 70-30 split, with the full 3.8 million yuan recovered. After Su Nian gives birth, Lin Bei obtains custody of the child. Having weathered the storm, Lin Bei learns to stand on his own and continues moving forward alongside his brother, Zhao Yang.
