The year is 2832. Earth has been destroyed by nuclear war. Chae-on, an outcast in a research group searching for humanity's new home, is discarded like a useless pawn and dispatched alone to the unexplored Planet 99. There, he discovers signs of new life. However, his joy at finding hope for humanity is short-lived when unidentified alien creatures suddenly attack him. But these guys... Why do they keep hitting all the right spots?! Pushed to the brink of dying from pleasure by their relentless and forceful probing, Chae-on is entirely overwhelmed. At that exact moment, a mysterious boy appears before him.
