During a heavy rainstorm at three o'clock in the morning, Lin Xiao, a delivery boy, accidentally touched a mysterious electric current and awakened the power of "traveling back three seconds of time" - which he thought was just a life-saving skill to avoid being punished. However, during a meal delivery, he witnessed financial tycoon Chen Yan personally controlling the stock market crash, causing hundreds of retail investors to jump off the building. In three seconds of retracement, he reversed his fate for the first time: he exchanged a piece of hot soup for a human life. From then on, he is no longer a food delivery boy, but a "karma liquidator" who travels through the gaps in time. Chen Yan didn't know that he was being used by a low-level ant to tear apart the shady story of the financial empire bit by bit with takeout orders. When every delivery becomes a secret battle, when every second of retrospect rewrites the outcome of a family, Lin Xiao finally understands: the real power is not to reverse time, but to awaken people's hearts.
