This was fantastically done, and I'm going to go sob in a corner. Seriously. I've read Cloud lives forever fics, but they were way too emotionally written; your style here is emotional, yes, but more in the sense that it lets the readers own emotion bleed in, rather than you forcing yours upon them.

The Zack and Aeris leaving bit also left me wincing horribly. This was a lovely piece, thank you.
