Shortly after your initial, inexplicable arrival in Equestria, you were taken under the wing - literally and metaphorically - of Princess Twilight Sparkle. She's a decent enough teacher, her assignments are straightforward and manageable, and you even get free room and board at her castle.

However, there's one problem: since your lessons began, you've been locked in a bitter rivalry with Starlight Glimmer, who was Twilight's only pupil before your arrival. This prompts your teacher to send the two of you on a special friendship mission together to help you get along. What she doesn't predict, however, is just how close the two of you will get after this adventure.

Will probably get some sort of follow-up eventually.
