Summary
Sometimes, when you look at yourself in the mirror, you can't help but wonder "Why am I here?"
You knew your mom wasn't in love with whoever your dad was.
And you knew she gave up everything-her friends, her physical form, everything she truly cared about-to have you. But...why? She was everything you could never manage to be, confident, strong, friendly, perfect, and to top it all off, she would never stop until everyone around her was happen.
You're absolutely nothing like her, and everyone knows it.
Well, almost everyone knows. There's one person who doesn't know, or maybe he just doesn't care.
Steven Universe. Anytime you start to doubt your existence and yourself, he's always around, lifting you up and admiring you in ways you didn't know were possible.
You've been friends for your whole lives and he still admires you, somehow even more than before...
You can help but admire him more too. He means everything to you and more.

Summary
This is a fanfic about Lapis Lazuli and Sapphire's relationship before the war. This is cannon (in my heart) and I try to keep the story on track with the real Steven Universe timeline as best as I can. If you love toxic yuri this is for you. I proof read as much as I can but if I'm being completely honest there probably are still mistakes. Please enjoy! <3

Summary
"Human sex," Chuuya says, letting himself be disdainful. He's allowed to hold contempt for a human activity.
But he's definitely not allowed to want his Diamond to use him for pleasure instead of a fucking human.
Dazai laughs. "You don't have to say it like that."
How do you want me to say it, my Diamond? How do you want me, my Diamond? Please, please just want me. I'll do anything.
Understanding sparks in Dazai's dark eyes. "Are you jealous, Chuuya?"
"Don't call me that!" Chuuya snaps. His head buzzes with static; hands curl into fists.
Dazai's eyes narrow. "But it's your name."
"I don't have a name." I'm not supposed to. Vibrating with repressed anger, Chuuya steps back. He wants to hurt Dazai—hurt his Diamond—in all the ways he's been hurt. Dutifully, he holds it in. He grits out, "I'm your Pearl. Stop acting like I'm not."

Summary
“Fusions are not made from power,” All-Might said, laughter rumbling beneath the microphone’s static, “Even when it’s two heroes. They’re made from trust. From choice. What you become says as much about you… as it does about the person who stood beside you.”
He shifted, gaze surprisingly soft behind the press lights, “People think it’s a technique. A strategy. But it isn’t. Fusion isn’t a show you put on—it’s a way of being. It’s what happens when two souls stop trying to be separate.” He smiled like it was obvious, like everyone knew what it felt like. Which was ironic—he’d only fused twice in his entire career.
Izuku could relate to the hero in a strange way.
After all, he'd only ever fused once.

Summary
The rain was coming down harder than usual.
Garnet stood beneath the awning outside Forks High, watching the parking lot as it had personally wronged her. The clouds were low, heavy, predictable. Jasper stopped beside her, careful not to crowd. “You don’t mind the rain,” he said. “No,” Garnet replied. “It’s consistent.” He nodded thoughtfully. “I respect that.”
After a moment, Garnet held out her hand. “Walk me home,” she said.
Jasper froze—just long enough to be noticeable—then took her hand like it was sacred.“Yes, ma’am,” he said solemnly. Then added, dead serious, “Though I should warn you, I am prepared to fight God, gravity, or any puddle over two inches deep on your behalf.”
Garnet actually laughed.
Behind them, Edward Cullen froze mid-step. He heard it all. Every infuriatingly sincere thought Jasper had about eternity and choosing her forever. “Oh no,” he muttered.
Alice appeared at his side, grinning. “Oh yes.”
Edward turned away sharply, hands clenched, staring into the rain like it might absolve him. “I have lived through a century,” he whispered. “And this is how I suffer.”
The rain never touched them.
Edward, unfortunately, was soaked.

Summary
[Based off of a FF.Net Fic by the Author, LibraMoon, who wrote a lot of fem!america]
When they had first fused, it was out of desperation. No one had wanted to do it at first. They were too different, too out of sync.
But the next time was no accident.
