Twilight Sparkle, a magical pony princess, has fallen in love with Brad Flash Sentry, a human from an alternate dimension. Huh, seems very unlikely for this to happen what with all the Brad haters who don't like him because he's stolen everyone's waifu and is portrayed as an undeveloped and boring character. Happily Sadly (For Twilight it's sad.), the princess finds out that the human Flash Sentry and her friend, Sunset Shimmer, are now dating.
Heartbroken, Twilight begins to doubt herself in being able to find love. But when the pony counterpart of Brad Flash Sentry is stationed as Twilight's new line of defense, how will she handle it, and how does Brad Flash Sentry feel about the princess and his new position even though hardly any fan of the show gives a damn?
