Chen Hai, who had been working abroad for many years, returned home full of heart with gifts, only to be met with a divorce agreement thrown out by his wife, Su Qing. Chen Hai insisted that he sent twenty-five thousand home in full every month, but Su Qing only received three thousand each month, and the huge gap caused the conflict between the two to erupt.

Their daughter Duoduo was caught in the middle, suffering from illness, and scene after scene of misunderstandings piled up layer upon layer. The whereabouts of this huge sum of twelve years became a mystery, and a hidden secret was concealed in the mother-in-law's room. A truth hidden beneath the family fireworks was slowly surfacing.
