30-Year-old Lin Chen is the most common "denominator" in a big city - he was squeezed into being a scapegoat in the workplace, his crush on the goddess of ten years is married to a rich second generation, his parents are seriously ill but he has no money to treat him, and even his former best friends are drifting away because of his "no future". After getting drunk, he accidentally activated the "Life Correction System" from the future. The system can trace back every key "regret node" in his life and give the optimal choice. However, each correction requires completing the corresponding "life mission", and failure will face unknown penalties.
Starting from revising a key workplace report, Lin Chen corrected his mistakes step by step: he recovered the promotion opportunities that were stolen from him, helped his parents avoid health risks, reunited with the goddess with a new attitude when she was at a low point in her life, and under the guidance of the system, she seized the entrepreneurial opportunity that she had missed. However, as the number of error corrections increased, he discovered that there seemed to be a secret about "parallel lives" hidden behind the system, and every seemingly perfect correction could trigger a chain reaction and even attract the covetousness of other "error correctors". Lin Chen gradually understood that real life is never about "correcting mistakes" to perfection, but about learning to take responsibility in choices. In the end, what he wants to do is not to become a "perfect life template" controlled by the system, but to control his own life with laughter and tears.
