    Summary

    【THIS STORY WAS ORIGINALLY POSTED AND DELETED BY ME HERE, SO WELCOME BACK IF YOU SAW THIS BEFORE!!! I MAY UPDATE THIS FROM TIME TO TIME, BUT I LOVE IT SO MUCH I COULDN'T TAKE IT AWAY FROM AO3 *CRIES*】

    Oh how you made his heart go ‘thump-thump-thump’.
    How he wished he could make you go ‘bump-in-the-night’.
    How you enticed him so tightly, that he could only think of you for days on end.

    How delicious your powerful soul was.

    You were so peaceful and round in this sharp and edgy world. All you would do was bless this shithole called ‘home’ with your sweet and untainted personality.

    How could he simply let *HIS* sweet little angel get away like that? How could he let her go unprotected in this filthy, nasty world?

    How, oh how, could he have the audacity to not call you his?
    You were, after all, his little Femme Fatale :)

    Summary

    He had been having dreams of the same cute little drunk human for almost a year now. They were vivid and she was fun to talk to, and he was convinced that his 'dreams' were accidental manifestations of her magic. Magic she didn't even realize she had. But that magic may have just pulled her into a world of danger.

    (not sure where I'm going with this but I love mafiafell sans. Lets see how this goes. Constructive criticism welcome. I'm a writing noob.)

    Summary

    You met him at a bar.

    To be fair, it was a very nice bar. You didn't usually go to those kinds of joints straight after work, but it had started raining, and you were not looking forward to getting soaked. Thankfully, you had noticed Grillby's open, and it was awfully convenient. It being in the 'monster' side of down didn't perturb you. Monsters were already involved in your life.
