45-year-old Lin Xiumei guards a small breakfast stall, but her ex-husband struts in with his new love to show off, throwing down an invitation and telling her to bring a partner to humiliate herself. In a fit of anger, she blurts out on the spot that she will bring a man a hundred times better than him to crash the place! Right after, she bumps into Zhao Guodong, a man with a proper demeanor, and hires him as a fake partner for a daily wage of twenty yuan. Who knew this 'temp worker' would get more and more into character, excelling at holding his ground, shielding her, and fixing electronics. The more her ex jumps around, the harder he gets slapped in the face, while Lin Xiumei's life gets more and more flavorful—turns out leaving the wrong person is the start of a good life.
