A flip of a coin. A twist of fate.

Twilight Sparkle, younger sister of Princess Celestia's personal student, Shining Armor, grew up listening to her brother's bygone dreams of joining the elite of the elite: The Royal Guard.

Now, fresh out of the Academy, this young mare is ready to prove herself equal to the deeds of the great soldiers she read about as a filly. Too bad the princess she ends up protecting isn't Celestia.

As a thank you, and upon seeing the potential in her, Twilight Sparkle has invited Sunset Shimmer to be a part of her team. Sunset has absolutely no idea what she's doing and she does not feel like she belongs; Whether if its from her regrets of trying to pursue power desperately and being corrupted by it, or her immense failure as Celestia's first pupil, or even her general inexperience with friendship, Sunset Shimmer has been humbled into nothingness, and has to rebuild her life from scratch.

And most complicated of all, Sunset Shimmer is now in love with Twilight Sparkle, the girl that changed her life for the better, and saved her from herself. She will keep these feelings extremely close to the chest; but her heart is on her sleeve now.

Can Sunset Shimmer improve? Can she be worthy and deserving of the friends that were imposed upon her? Could she possibly ever deserve to be side by side with a princess? Can she earn Twilight Sparkle's love?

Can she belong? Or is all of this temporary... And eventually she will have to move on, to anywhere more fitting of her insignificance? Are things destined to go wrong around her?

Will Midnight Sparkle return?
