Immortality is a mysterious, curse-like disease with no origin and unknown transmission route. People who suffer from it cannot die and live forever with the world. The one in two billion undead can only hide in the darkness of this world, pretending to be ordinary people and continue their endless lives.
One is the leader of the elite special forces team that names the entire FBI, and the other is an international killer with mysterious origins. The collision between the two is destined to be irreconcilable. In the chase and wrestling, who is the prey and who is the hunter? Who wins in the future, and who loses to fate.
Irresponsible version of the copy: In short, it is a series of love and killings that happened after a random killer was accidentally targeted by the scary guy from the FBI, and a story about the undead, who can't die if they are not careful.
