Alien

Humans were the rarest species known to Namjoon and his kind. Every time a human space craft was spotted, numerous search parties were sent to find and bring the craft back. Namjoon had been put in charge of gathering information of humans, in all ways possible. Whenever he was finally sent out to learn more about the elusive space creatures, he finds something, and someone, that can completely turn what Namjoon had thought he had known about humans.
