Kelle and Arjun are best friends.
Kelle and Arjun have never met.

They live in different pods: underground settlements separated by long stretches of strictly regulated tunnels, each pod sealed off to avoid viruses and other plagues devastating what remains of humanity and its food sources. Even romances, to an extent, are regulated. But people can still communicate via landline telephones, and people can still fall in love, even from afar. So when the government in control of the North American pod system has determined it's time to make a trade of goods between Pod North and Pod West, the human inhabitants of each pod are also welcome to petition for a transfer.

It's time for Kelle and Arjun to meet.
