Princess Cadence decides to enroll in public high school for her senior year after being tutored all her life, to get a taste of other ponies her age. What she doesn't expect, though, is to fall for the most important stallion on campus- Shining Armor, captain of the wrestling team, and boyfriend of the most beautiful mare in the city, Fluer De Lis. Despite all this, she does make a new best friend, and land an excellent job foal sitting for a pretty little filly, Twilight Sparkle. But will her love for Shining Armor ruin all the friendships she's managed to build?
