Shen Ruoxi's parents selflessly cared for their grandson for five years, yet her husband Lu Zeyuan heartlessly drove the elderly couple away, turning around with the intention of bringing his own parents to the city to enjoy their old age in comfort. Shen Ruoxi implemented an AA system, splitting living expenses item by item to make Lu Zeyuan personally experience how difficult it is to manage a household. Having witnessed the pressure of life, Lu Zeyuan suddenly came to his senses, proactively repaying the expenses his father-in-law and mother-in-law had given over the years, and learned to treat both sides' elders with equal kindness. The family came to understand one another and lived harmoniously.
