Unmarried and pregnant with fraternal twins, Wen Qiao makes a living running a street stall. To cope with Elder Gu's urge to marry, she enters into a flash marriage contract with Gu Yushen, the person in power at the Gu Corporation, to fake being a married couple. After marriage, she moves into a wealthy family and joins the Gu Corporation, successively suffering harassment and framing from Bai Muning, the adopted daughter of the Gu family, and repeatedly encountering danger in the workplace and at a birthday banquet. As clues emerge, Wen Qiao learns that Gu Yushen is the biological father of her children, while also discovering that she is the long-lost biological granddaughter of the Bai family. Bai Muning kidnaps Wen Qiao to seize her identity, ultimately reaping what she has sown. The two clear up their misunderstandings, give up a grand wedding, donate the money to an orphanage, and run towards happiness.
