So, yes, I'm promoting a story contaning a very rare shiping. It's so rare that, infact, it's the only fanfic I know about containing this shipping.
Stripeds Scars
Zecora has been missing for months and Fluttershy is starting to get worried over her striped friend. Against the advice of others, she sets off alone to Zecora's hut, deep within the Everfree forest.

Now join me readers, as we delve into the world of Equestria and and watch the friendship of these two mares grow into something much, so much more.
But what happens when their dark pasts are revealed and they learn that sometimes, you simply can't ignore the nightmares.
As you can guess allredy in the description, this is (as far as I know) the one and only Zecora x Fluttershy fic that excists on this site! It provide you with a steady portion of the feels, and allready after reading the first chapter, you'll feel a hunger for more of this fantastic, well written story!
So give it a read!
