After seven years of marriage, Shen Ning has lived frugally and worked hard to support their family. But when her husband, Cheng Yuan, mistakenly believes he has won 38 million yuan in the lottery, he hides the ticket and conspires with his first love to kick her out with nothing. Shen Ning does not fight back. She simply signs the divorce papers and walks away. Cheng Yuan throws a celebration party and borrows a huge sum of money to open a business, eagerly awaiting the public prize claim so his ex-wife will regret leaving him. What he does not know is that the ticket in his hands is worthless, and the real prize money has already been deposited into Shen Ning's account. When the day of the claim finally arrives, his dream of becoming rich crumbles in front of everyone, while his five-million-yuan debt comes due. Only then does he remember the seven years they spent as husband and wife.
