Rarity and Rainbow's wedding is coming close and all Equestria is excited about it, but something may interfere in both mare's happiness...

A.N.: sequel to LFL 1 and 2, it is not totally necessary but if you want to read those, here they are: LFL:1 and LFL:2 also, there MAY be mature chapters but they'll have a warning on the chapter title and the I tagged the story as AU since there may be small "uncanon" events/references.
