Worldbuilding
We see Seok-woo's world of selfish corporate dealings and emotional distance. Background news reports hint at a spreading disease. His sister tries to get him to spend time with Su-an. The normal world is established—but with ominous undertones of chaos breaking loose outside.
Disruption
