(David: Better title needed. Suggestions?)

No suggestions but this fic is definitely not bright enough for its title.

"<Well, okay.  I'll see you when I get back.>"

People always forget. Belldandy goes to the same classes as Keiichi, the 
better to be with him.

It was there that she first realized something was wrong.

She should have realized it when she couldn't feel her angel. The only 
being closer to her than Keiichi.
I guess this is why the epilogue of Dire Fates turned out the way it did. I 
don't suppose you'd care to tell us now if Belldandy's condition is long 
term or not.

Keiichi looked up from his mechanic work.

You'd think he'd be beside himself trying to help Bell-chan come to terms 
with her situation.

Sayoko Aoshima smiled.

It's Mishima Sayoko.

(David's Note: This seems optional. Is it worth it if I expand on it?)

You should expand it and use it to show how Belldandy is uncertain she can 
hold on to Keiichi as a mortal.

She didn't know what she would do without him now that she was truly 

mortal.

Two things I would see Belldandy worrying about as a mortal. One, her 
insecurity in holding on to Keiichi. Two, that she could not protect 
Keiichi from any supernatural enemies without her magic. You've seen the 
first, can you use the second as well?

Belldandy found herself becoming tired frequently from mere

daily chores.  The wind seemed a bit more harsh, the sun a
little more stinging to the skin.<<

She probably was using her magical reserves to do her chores before.

Sometimes, when she was watching the television, she thought she saw Urd.

As if she ever has time for that?

This fic is good. It parallels "Falling..." that was written some time ago. 
I hope it ends on a better note.
