Fluttershy has always been a timid pony. It was a truth long accepted until the day she met her one and only love: that stallion who cared for her, protected her, and sheltered her from any harm... a stallion as quiet and as shy as she was.

In his embrace she grew, learned, laughed, and loved. She reached out further into the world than she ever had before, and with his support she became that mare she always dreamed she could be.

Now, as she stands overlooking the world, her memories of their times together will keep her warm when his hooves no longer can. With her final hours and the remembrance of their life together, her life will slowly fall back into place. With his confidence and her love, nothing can shake her. Now, at the end of everything, does she understand how it all went wrong.

What she doesn't understand, however, is that she's wrong about everything.

Rated teen for some sexual references (but no Clop).

Fluttershy and Big Mac used to live a happy, carefree life together.

Now Big Macintosh is one of Celestia's greatest soldiers in the war against Discord. Fluttershy is a trusted Elemental General, one of six.

Equestria: Blocks the memories of soldiers to cut ties. Makes all soldiers sound the same. Uses the Elements seperatly, thanks to Twilight. Has Spike, now a large, pony-crushing, 50 ft. tall dragon.

Discord: Misshapes soldiers. Whispers lies of hatred, and forces soldiers to murder close relatives. Has own Elements. Has Discord.

Discord is winning.

Real original, I know. Rated teen for (so far) sexual references and mild cursing.

If you downvote this story, please tell me why so I can improve.

IF YOU ARE A TOUCHY PERSON, I SUGGEST NOT READING THIS.

Fluttershy has a delicate situation. She has been fussed over by a certain stallion, yet another colt is after her as well. Soarin and Big Macintosh are competing fiercely for Fluttershy's affection. The yellow filly doesn't know what to do; the two stallions aren't consulting her for the decision, but it wouldn't matter either way, as she doesn't have a clue which stallion she'll choose.

Big Macintosh is finally going to marry Fluttershy, but he doesn't know how he should propose. To figure out how, he asks his three best friends for advice: Caramel, Mr. Cake, and Braeburn. Hilarity ensues when Big Mac tries to propose. Will any of his attempts work? Will Big Macintosh propose to Fluttershy, or will he fail?
