Mujonjaegam

The world was transformed into a world where many people were turned into cannibalistic monsters due to an unknown virus, and the screams of the dying were swallowed up by the cries of the monsters. Kim Jong-Do, a boy who had lived a dark life because he was not paid attention to by those around him due to his innate lack of presence, survived the apocalypse because he was not paid attention to by the monsters either, and for some reason, Kim Jong-Do was able to communicate with several monsters. While he was trying to relieve his loneliness a little by communicating with the monsters, he met Jo-Myeong, a female student from his high school class, by chance. Unlike the indifference of those around him, she was one of the few people who took interest in Kim Jong-Do, and in this way, Kim Jong-Do's 'sense of non-existence' began to shake.
