Some Random Idea for a dA Story I Have

(WARNING: THIS IDEA IS FAIRLY DARK AND MAY CAUSE TEARJERKING)

I had a dream last night where I was spending the last few hours of a girl's life whoum chose me. And when I woke up, I had implanted an idea in my head about a story I should do on dA. It's about a teenage boy (name not yet thought of) who lives in a pre-apocalyptic future where terrorists unleash a un-curable disease on the US, which has infected his girlfriend (still not yet named) as well. When the girl has 72 hours left to live, she chooses her boyfriend to spend her last 3 days with. So, they begin to bond even more together even to the verge that they care for each other more than anything else. but eventually the final hours of her life become shorter and shorter, and they realize they have to give each other up. That's all I have for right now, I'll think up more and you may or may not see this on Deviantart. Discuss below your opinions.
