Taewoo, who won't die no matter how badly he bleeds, becomes the big shot of a gang because of his unusual constitution.

One day, on a request from his boss, who he considers a father figure, Taewoo checks out a place where gang members are known to often go missing.

There, he comes face to face with an unknown man who survives on the blood of other people...?

"You don't die no matter how much you bleed and I need to drink blood to live so... our encounter is really like fate, huh."
