Shen Yuan has a secret - he can't die. It's not the kind of person who has a "tenacious vitality" who can't die. It's the kind of person who can get up from his workstation at six o'clock the next morning even if he really dies. In the past ten years, he has tried to resign, change jobs, and even be fired on purpose. But no matter which company he went to, he would wake up the next day and return to the cubicle where he worked. His status in the HR system is always "on the job", social security is always being paid, and he can't even print out his resignation certificate. What's even weirder is that only the cleaning lady in the company can see him, and no one else can even sense his existence. Until one day, the new intern Lin Nuan handed him a cup of coffee: "Senior, what are you doing lying on the floor? Looking for a pen?" Shen Yuan was seen by his colleagues for the first time, and realized for the first time that he was trapped in this office building. Maybe it was not a coincidence at all.
