Lu Chen was subjected to ledger-style strict mistreatment by his parents since childhood, settled old accounts and left home at eighteen, and became an investment banking director ten years later. His parents and younger sister demanded that he bear the down payment for the marriage home and the dowry, but he presented his childhood ledger, declaring that he would support them legally from then on and would no longer bear extra burdens. Relatives booked a yacht without authorization and purchased extra gifts, attempting to make Lu Chen pay the bill, which he refused to pay on behalf after verifying the contract and signature records. The other party subsequently published false videos and harassed him at the company, and Lu Chen clarified the facts with evidence such ledgers, recordings, and surveillance. Eventually, the relevant parties settled the payments according to their responsibilities, and Lu Chen restored his position and was promoted to partner, handling the boundaries of support and debt legally and starting a new life.
