I wrote two songfics (fanfictions based on a song) on the ship MorMor. Because of FFnet's rules, I'm not allowed to publish a text that contains extracts from other authors (in this case, song lyrics), so I had to delete them. I had read that kind of fics here before, but mine got striked down so I won't insist. That said, you can still read them on AO3.
1) Bang Bang:
He shot me down, Bang Bang
When he fired that gun, right into the centre of his skull, it killed me as surely as it killed him. That bullet went through his brains and through my heart. And you can't live on with your heart missing.

2) Oceanographer's Choice:
What will I do when I don't have you to hold on to in the dark?

(note: I will edit this document if I write other songfics.)
