Lin Yuan, an invisible presence in the workplace, is deliberately left behind when his team charters a plane to Xiamen for a company-building trip. A photo of the empty seats shared by his colleagues, accompanied by the remark, "What a shame. Someone just doesn't fit in," becomes the final straw. He turns off his phone and falls into a deep sleep. When he wakes up, the world has been turned upside down—88 missed calls, hundreds of WeChat messages, and even the CEO personally showing up at his door. That's because nobody in the entire company knows that the core of a multimillion-yuan proposal and the lifeline of its servers both depend entirely on him. When everyone begs him to put out the fire, Lin Yuan's counterattack has only just begun.
