After Fang Xiaojie's death, he was reborn as Gu Yanhui and became the guardian of his brothers. The brothers are all villains: the eldest brother of the 29-year-old company president, the second brother of the 27-year-old paranoid doctor, the third brother of the 25-year-old men's group C, and the younger brother of the belly black school bully. Although Fang Xiaojie only saw them as tasks, the brothers had different ideas. Once in the bathroom, when Fang Xiaojie was about to flush, the second brother suddenly appeared and blocked the button, and forcefully asked him to leave, and let Fang Xiaojie glance at the "Ah Hui Fecal Observation Manual" in his hand. When shopping with the eldest brother to buy clothes, the villain traits of the brothers are also beginning to emerge.
