When We Were Legends

Two kids; one dying slowly and one dying quickly, both wasting away. Instead of letting death cripple them, they decide to take death as a challenge and make sure whether they died tomorrow or in fifty years, they'd be remembered but not as the boy with the terminal illness and the girl with the eating disorder but as legends.

"Oh how silly we were to think immortality meant living forever,"

ps: this isn't a dark story!
