The father has been supporting his brother-in-law without any bottom line all year round, draining the family's wealth. The mother only relies on a monthly salary of 3,000 to support the whole family. Unbearable, she filed for divorce and asked her son to choose sides. However, the son took out his marriage certificate and admitted that he had already changed his surname and separated from his original family. He detailed the past of his father misappropriating his scholarship and neglecting his family over the years, and presented evidence to demand that his brother-in-law and his father repay the debt. In the end, the mother successfully divorced and started a new life, while the father and brother-in-law, who blindly supported his younger brother and ignored his family, also came to the end they deserved.
