When salvation becomes a curse, every reincarnation is signing a stranger's death notice for the one you love. After pushing his lover away from the wheel for the ninety-ninth time, he saw the full picture of the cruel rules - this world filled every modified destiny gap with random lives. Reborn for the hundredth time, he chose to walk to the truck in advance, but attracted other observers who noticed the phenomenon of reincarnation: scientists obsessed with data, police officers who discovered probability anomalies, convenience store clerks with memory flashbacks, and taxi drivers who saw the truth from the driving recorder. Six mortals trapped in a time rift faced off against the approaching Möbius loop in a convenience store all night long. When the footsteps of the ninety-nine dead substitutes gather from all timelines, they must make a decision together: continue this infinite cycle of equivalent sacrifices, or find a third possibility to break the law of cause and effect?
