You and Percy have been best friends before you were even born. Sally and your mother were high school best friends, who just so happened to get pregnant at the same time. They always joked that if one of their children was a girl--and one of them a boy--that they would get married when they were older.

Of course, this was a joke. But as both of your mothers watched you and Percy grow up together--fighting over sippy cups full of Goldfish, picking out each other's outfits, giggling together in the homemade treehouse that you both made--your mother had been bugging you about liking Percy, and Sally bugging Percy about liking you.

Flash forward 10 years, Percy and you are both 17. You are sitting outside on Percy's fire escape at night, staring out at the hazy city lights as Percy leans his head back against the building. You grab his hand and squeeze it when you notice that he looks lost in thought.

He looks up at you and gives you a warm smile. "What's up, fish?" A childhood nickname from the time that you had gotten a fish drawn on your face by Percy when you were asleep.
