Review:
The Horizon takes place during the aftermath of some kind of massacre (the Webtoon page says it was an apocalyptic event). A young boy is the sole survivor of some kind of event that kills his mother and pretty much everyone else in the city. With nothing else to do, he walks and eventually finds an abandoned school bus to sleep in. A girl his age also finds the bus, and the two of them become sudden traveling companions as more violence breaks out around them. Eventually they come across a third person, a grown man who seems to only be capable of screaming like a crow. Although the girl is fine with him following along, the boy can't help but be frightened and wary of the man.
