Steven Universe Fanfic: Have I Ever Told You...
Ruby and Sapphire are in high school. Ruby's attractive, strong, and cool but has a few anger issues. She pretty much rules the school. On the other hand, Sapphire normally goes unnoticed by everyone but Peridot, Pearl, and Rose Quartz. Ruby's friends with everyone but her best friends are Jasper, Lapis, and Amethyst. (Human AU)
Sort of like Romeo and Juliet without the crazy death story.
(I have to admit, not my best work, but when you're bored you just gotta write random things and hope it works.)
