For 3.8 Yuan to buy groceries, the father mistakenly swiped his son's family card and was immediately released and humiliated by his daughter-in-law. The frustrated father stopped repaying his son's loan, and ended his years of forbearance - selling his house to collect the down payment and monthly subsidies, but only received a 50 yuan credit and "sense of boundary" criticism. When the fake pregnancy scam was exposed, a hidden "Investment Agreement" became the ultimate trump card. The father resolutely filed a lawsuit, recovered the house payment, and found himself in the breakup. This is not a three-eight war, but a sober rebirth of a father taking back his dignity and teaching his giant baby responsibility.
