After the wonderful experience of being a pony for a day, Sonata Dusk makes a wish for her friend Aria to be one for the whole weekend, much to her friend's expense.

Adagio discovers that she has a crush on Aria, but after walking in on a rather intimate moment between her lackeys, she'll do whatever it takes to make Aria all hers... by any means necessary.

Aria has an upset stomach. Adagio offers help, but why?
