Established Facts and Remaining Uncertainties

Production Background and Series Context

The series adapts the webtoon “Now at Our School” by Joo Dong-geun, maintaining the original’s setting within a high school microcosm during societal collapse. The production utilized extensive practical effects combined with CGI to create the infected, requiring coordination between stunt performers and the main cast.

Director Lee Jae-kyoo and writer Chun Sung-il collaborated to translate the source material’s horror elements while expanding character backstories. The show represents a significant entry in the Korean zombie genre, following the success of films like Train to Busan but extending the narrative across multiple hours of television.

The ensemble approach recalls other large-cast survival dramas, though the high school setting provides unique dynamics regarding hierarchy, bullying, and academic pressure exacerbated by the apocalypse.
