"Not every fairy tale has an happy ending."

And a sad ending may have been what this fic needed. You had a very good
buildup, but the ending was a let down. Look, I wanted Belldandy to live as
much as you do, but the way you went about it was... disappointing. it
lacked the emotional impact.
Unless you can rewrite the ending for better impact, you may have to let
Belldandy die.
Looking forward to reading the completed version of this fic.
