Lin Wanwan married into the Chen family seven years ago. Every household expense, from daily necessities to food, clothing, and other living costs, was meticulously recorded in a ledger. When her father-in-law suddenly fell gravely ill, the family needed 500,000 yuan for surgery. Her mother-in-law declared matter-of-factly, "You're the daughter-in-law. Paying for it is only natural." In the family group chat, five relatives each sent a red envelope containing just 5 yuan before collectively disappearing. Lin Wanwan opened her ledger. Her contributions over the years were clearly documented, totaling 870,000 yuan. Meanwhile, every penny of her husband Chen Jianjun's 670,000 yuan salary had gone straight into his mother's hands. Only then did she finally understand: the ledger she had kept for seven years wasn't a record of her contributions. It was proof that she had never truly been considered part of the family.
