Sixty-four-year-old Xu Xiulan entrusted her son Chen Li to collect three years of storefront rental income. Believing this was a secure retirement fund, she discovered when the roof leaked and desperately needed repairs that over 100,000 yuan had been secretly misappropriated by Chen Li to rent a high-end elevator apartment for his former mother-in-law for two years. She decisively took back the rental account and demanded her son return the debt. Amid continuous demands and debt pressure from his ex-wife's family, Chen Li suffered setbacks one after another, lost his job, and sold his beloved car. Finally recognizing boundaries, he took the initiative to assume responsibility, and the mother and son rebuilt a healthy mode of getting along after clarifying financial boundaries.
