[Tifa heaves a whimsical sigh.]

[This is just the Hopeless Romantic in her talking. One of her favourite past times is stargazing, back when she could see them in Nibelheim, so the thought of being completely surrounded by them is something that could only happen in dreams.]

I'd love to go up there sometime... See what it's like. Maybe play a little song.
