On the wedding night, the wedding gift card of the bride Lin Su was inexplicably deducted for the mortgage of bridesmaid Xu Rou, and she unexpectedly became the co-payer of the other party's mortgage. She saw through the conspiracy of her fiancé Zhou Haoming and ten-year friend Xu Rou joining forces to impersonate her identity and attempting to use her gift money and credit to repay the mortgage. Lin Su calmly collected surveillance and bank evidence, tore off everyone's disguise, decisively stopped the losses, broke free from the scam, and ended this marriage full of calculation.
