Keep my Secret (pearlmethyst fanfic) by scaldera3

What sucks about having a crush that'll never like you is that you keep hoping that they will, but they never do. And only one person knows how to help with this kind of thing. Someone in a relationship. Someone that sucks at lying.

Of Gems and Demons by JungleFurious

A young man comes to Beach City, hoping to find answers about his past and where his future might take him after his mother died. There he meets a young boy named Steven and his four caretakers called the Crystal Gems named Garnet, Amethyst, Pearl, and Spinel, with the four of them knowing his mother. What he never expected when he met them was to be pulled into an adventure he'd never thinker he be a part of. He will go up against other Gems from outer space, crime lords, and demons, but he will not face them alone. The odds are against them, it won't be easy, but they're not going to do this alone. Why? Because they are the Crystal Gems, they always save the day, and if you think they can't, they always find the way!
