Sun Xiang, the takeaway webmaster, was involved in a car accident on a rainy night while working overtime continuously. When he was about to die, he awakened to the "Cause and Effect Book", a selection system. The system appears in the style of an ancient book, with 2-3 options popping up for each key event. Different plot lines will be triggered after selection, ranging from handling customer complaints to major turning points in life. The consequences of the options include explicit rewards (money/connections) and hidden causes and consequences (prestige/karma). Under the guidance of the system, Sun Xiang, who worked at the bottom, gradually got involved in the undercurrents of the business circle, emotional entanglements and self-salvation. In the process, the old voice of the system's "bookkeeper" gradually revealed the mysterious origin, and finally had to make the ultimate choice between "peak life" and "ordinary happiness".
