The 99th Planet

The year 2832. A future where Earth has been destroyed by nuclear war. Chae-On, an outcast in a research group searching for a new home for humanity, is sent alone to “Undeveloped Planet No. 99,” like a discarded card. There, he discovers a signal of new life. But his joy at finding hope for humanity is short-lived, as unidentified alien lifeforms attack him. But these creatures... Why do they keep picking on the places that feel good?! Driven to the brink of death by their ruthless and coercive search, Chae-On is on the verge of collapsing. At that moment, a mysterious boy appears before him.
