Cadance invites Shining Armor to the castle to meet her Auntie Celestia. Of course Shining is nervous, seeing as Cadance's Auntie is the ruler of Equestria. 

Cadance makes Shining an offer he can't refuse: if he can be on his best behavior and impress her Auntie, she'll give him a little "reward." Unfortunately for Shining Armor, that's going to be easier said than done.

[Update:] (10/26/15) I decided the story would flow better if it wasn't divided into chapters.
