Lin Bin married into the Liu family eight years ago. He has always worked tirelessly and given everything without complaint, yet he has never earned the respect of his in-laws. As his brother-in-law, Liu Xiaonao, prepares to get married, his mother-in-law, Li Qingzhi, and Liu Xiaonao demand that Lin Bin pay for the wedding. They even pressure him to sign a loan agreement. Lin Bin finally decides to stop enduring their mistreatment and fight back. He brings out eight years of financial records, detailing everything he has spent on the Liu family, including home repairs, his mother-in-law's medical expenses, his brother-in-law's engagement, and monthly living allowances. Shocked by his detailed accounts and newfound determination, the Liu family begins to reconsider their behavior. Lin Bin and his wife, Liu Mengya, leave the Liu family home and temporarily move in with Lin Bin's older brother, Lin Dashan.
