My experimental love. Pearl X reader

Rose Quartz was not the only love pearl had lost during the Great War. Since she died last, you could consider her the second, even if pearl loved her first. The first person pearl had ever truly cared for though, was a gem who had been made in the kindergarten. She was a mixture of garnet, pearl, and diamond; the greatest fighter to ever live. Her name was Sophie Marin. She was given that name by the diamonds, who had taken her in on account of her being one third diamond. Sophie had grown up thinking the way of the gems, and when pearl had requested Sophie to join the rebellion, her immediate answer was no, and that's how this story began, with a certain gem saying no to the only person who ever truly cared.
