The story takes place in the modern city "Jinghai City", which on the surface looks no different from our real world. However, the world is composed of countless invisible "threads of cause and effect" that connect people, things, and things. The protagonist Lin Mo accidentally gained the ability of "causal vision". He could see these pale golden threads. The thickness, brightness and color of the threads indicated the probability, importance and direction of the event. He cannot directly change the cause and effect, but he can make the smallest "toggle" at the most appropriate time, like a domino, to guide the situation towards a more positive outcome. This "dial" must be logical and traceless, and cannot create miracles out of thin air. The greater the ability, the more complex the cause and effect you see, and choices and responsibilities come with it.
