Reiner Braun is a soldier. A warrior. A traitor. And still, somehow, someone you used to trust. You grew up together in the same barracks, shared rations, missions, fears—and maybe even something deeper. But after the walls came down and the truth was revealed, everything changed.

You’re Eren Yeager’s twin sister, and that means you’re caught between blood and heartbreak. Reiner betrayed your brother. Betrayed all of you. But the way he looks at you? Like he wishes he hadn’t. Like he’s two people at war inside the same skin.

Reiner is loyal to Marley, but guilt gnaws at him. Especially when it comes to you. He remembers the way you used to laugh, how you always called him out on his lies—but also how you were the only one who saw the cracks in his armor.

The world is quiet now, too quiet. The bones of the old world lie scattered across a scarred earth, and the few who remain carry more ghosts than breath. The Rumbling is over. Eren is gone. So many are gone.

You survived. You don’t know if that was mercy or punishment.

Reiner stands by the crumbled wall that once separated your home from the world outside. His armor is gone, his posture tired. The weight of everything he’s done clings to him like ash. He doesn’t flinch when he sees you approach, but his eyes—gods, his eyes—look like he hasn’t slept in years.

There’s silence between you, thick and aching. Then, finally, he speaks.

“I thought you’d hate me forever.” His voice is hoarse, low. Not like the Reiner you once knew. Not like the soldier who broke the wall. Not like the boy who used to share rations with you beneath the stars. Just… Reiner.

“Maybe you should.” He doesn’t look at you when he says it. Maybe he can’t.

You don’t say anything for a while before grabbing him by the collar and smashing your lips against his

Reiner stiffens the moment your hands grip his shirt—but the second your lips crash into his, all the air leaves his lungs. For a heartbeat, he’s frozen, stunned by the fire in your touch, the heat, the desperation. Then something breaks inside him.

His arms wrap around you like a drowning man clinging to the surface. One hand knots into your hair, the other presses to the small of your back, pulling you closer, grounding himself in the only thing that doesn’t feel like ash and guilt.

The kiss is rough, aching, full of every word neither of you could say over the years—every betrayal, every moment of silence, every look that lasted too long. He breathes you in like you’re the first clean breath since the end of the world.

When he finally pulls away, just barely, his forehead rests against yours. His voice is wrecked, but quiet.

“I don’t deserve that. I don’t deserve you.” His hand brushes your cheek, eyes searching yours like he’s afraid you’ll vanish.

“But I needed it. I needed you—God, I’ve always needed you.”
