Gu Cheng had been married to Su Qing for over twenty years when he discovered that his wife had been secretly involved with another man for fourteen years. He kept his discovery to himself, moving into a mahjong parlor at the end of an alley and pretending to be an incompetent, cowardly husband obsessed with gambling, allowing relatives and fellow players to mock him. But nobody knew that, in his younger days, he had managed project accounts for over a decade. Every text message notifying him whenever Su Qing used his supplementary bank card, and every contract and invoice the other man proudly bragged about, he meticulously recorded. Fourteen years later, when Su Qing became critically ill, she left all her school-district properties and luxury cars to that man right in front of Gu Cheng, mocking him for having spent his entire life playing mahjong and having nothing to show for it. Gu Cheng leaned close to her ear and whispered, "Actually, I have a secret of my own. I've been hiding it from you for fourteen years."
