Project manager Lu Jiang once entrusted three years of salary totaling over seven hundred thousand to his girlfriend Su Qingrou for safekeeping, keeping only 20 yuan a day for pocket money. On this day, his mother fell ill and needed 30,000 for surgery fees. When Lu Jiang asked his girlfriend Su Qingrou for help, he only heard "no money". At this critical moment, Lu Jiang borrowed money from a colleague to get through the difficult time. Afterwards, he learned that Su Qingrou had transferred Lu Jiang's entire salary to her younger brother Su Qiang. Lu Jiang decisively broke up with his younger-brother-obsessed girlfriend, and wanted to retrieve his money through legal means but encountered all sorts of obstruction from the other party. Can Lu Jiang recover his money, and where will his relationship with Su Qingrou go from here?
