Three Seconds of Precognition, I Reverse My Life

At 24, a low-level office worker from an ordinary family, timid and submissive, with no background, money, or power. He endures exploitation, scapegoating, and bullying at work, and his girlfriend of many years cheats on him with a rich heir, publicly humiliating and abandoning him. One rainy day, he accidentally touches a frayed wire and nearly dies from electrocution, awakening a precognition ability. His personality gradually shifts from passive endurance to calm decisiveness, ruthless judgment, and fierce protectiveness.
