When two world's collid

The year 3050 the air is always filled with smog u can very rarely see natural ground earth is now just a bunch of tunnels and passageways, if u weren't rich you where shoved down into the metal passage way to try and survive and if ur lucky enough u can find a underground city people live in peace, the rich on the other hand had so much kids normally went to school and got everything there heart desired, everything u could ever hope for. Kade is from the underground, while Tyler is from millennium city the capital of the sky city's what happens when they meet for the first time. (No pictures are owned by me)
