This story is a sequel to About Last Night
One month ago, Twilight Sparkle and Applejack got drunk and then got married.
Now Twilight's a princess, and the pair have to work on integrating that new aspect of it into their relationship. Add to that Spike's feelings on the matter and the fact that he's getting the attention of fillies his age, and Fluttershy and Rainbow Dash's relationship, maybe they're better off grabbing a few more drinks...
