During her unemployment Gap period, Lin Yao proposed a best-friend mutual support plan. After female protagonist Su Xiaoxiao sincerely fulfilled her commitment and paid, Lin Yao, having enjoyed the benefits, treated the agreement as a "joke", tore up the verbal agreement, and refused to fulfill it. Su Xiaoxiao's boyfriend Wang Jinglin disguised himself as a warm man, secretly colluded with Lin Yao, favored Lin Yao, and completely tilted his stance toward the victimizer. Suffering double economic and emotional damage, Su Xiaoxiao triggered the An Eye for an Eye system. The contract became mandatory, and the defaulting party Lin Yao must complete the support obligation. Defaulting will increase the contract duration --- fleeing to the ends of the earth, the bill follows like a shadow. This money, she wants to default on, but she cannot shake it off.
