Summary
Song Shushui dies and wakes five years in the past—with a gun held to his head by his younger self. To survive, he lies his way into the assassin’s guarded villa, planning to steal his identity and destroy the paternal and maternal clans that ruined his life. But the younger Song, calling himself Leviathan, soon uncovers the truth. They share the same face, instincts, wounds—and a dangerous narcissism neither can resist. As family conspiracies and a secret time-travel project close in, the two assassins must decide whether to eliminate each other or become the only partner either of them can ever trust.
