Today's the day! Twilight is finally going to tell Rainbow Dash how she feels, and it couldn't be a better day for it! But there's still plenty that could go wrong, including Rainbow saying no. Needless to say, things go wrong in a way neither of them could have imagined, and Twilight's day goes from bad to worse...

This is more or less just setup for the sequel, and the sequel is much better than this.
