This is the story of two ponies who happen to be in love saving Equestria. That's a fairly generic premise, but more specificity will only make it sound worse. Let's go down the list.
Chapters are way too short? Check.
Chapters are published out of order? Double check.
OC as the narrator? Check.
OC shipped with Trixie? Check.
Details on the shipping kept light enough to not satisfy people looking for a shipfic or apply the romance tag, but heavy enough to bother those against the ship? Check.
Poorly written? Triple check.
Time travel? Oh you best believe that's checked.
Peppered with references nobody's gonna get? Check.
There's no way this could possibly succeed. Let's do this.
