Relying on his pension, the father-in-law demands to split up their living arrangements. Daughter-in-law Su Nian readily agrees, immediately stopping the payment of various family expenses she had silently shouldered for four years. Losing the invisible financial cushion provided by their daughter-in-law, the household suffers consecutive water and electricity cutoffs. Facing the reality of overdue bills, the father-in-law finally realizes he was the one who had never contributed. Ultimately, the whole family unfolds the thick household ledger, the father-in-law reflects on the past, and a transparent household expense model is re-established. This storm brings the entire family true clarity and a warm reconciliation.
