The film lacks LGBTQ+ characters or non-heteronormative identities. The narrative focuses entirely on the survival mechanics of the two central protagonists.

A dual-protagonist structure features one male and one female character. Both are presented as equally capable in technical survival and resource management during the crisis.

The cast is ethnically homogeneous, reflecting the South Korean setting. It does not utilize diverse ethnic blending or race-bending to expand its demographic scope.

The story critiques modern urbanism by framing the apartment complex as a claustrophobic trap. It highlights the fragility of social contracts through the failure of institutional authority.

No characters with visible or invisible disabilities are portrayed with specific agency. Physical limitations stem from the virus rather than explored neurodivergence or chronic illness.
