A/N: First non-Rivetra fic!
It was a cool night at the boys' barracks in the training camp. It is usually loud and rambunctious within it due to everyone sharing one main cabin. Eren always slept early, he felt that he needed his rest to do his best during training. To do his best to exterminate the Titans.
The bell signaled awhile ago after dinner so that the cadets knew they must return to their cabin. But it usually took a few hours later until everyone went to bed, much to Eren's disliking. He was half awake, half asleep. Drifting in and out.
Suddenly, the door to their cabin opened and it became silent. Eren thought it was the Commander, telling them to shut up and go to sleep. He kept hearing whispers and mumbling, but ignored it since he was just about to fall asleep.
"Eren," He slowly opened his eyes, squinting to the sudden brightness. As soon as his eyes were able to focus, his green ones met grey ones.
"Mikasa?" He replied, voice strained from being tired. He sat up to rub his eyes. His eyes were hooded and tired, so he didn't notice that all the talking was about the two of them.
"Eren, I couldn't sleep" His eyes widened. He already knew too well what that meant. She thought about her mom and dad some nights and would wake him up because she was all shaken up. He nodded.
"Come here," She didn't hesitate as he put his arms around her with her head buried in his neck. He let go to pull the covers over them and then laid down. Her head was now on her chest, their arms and legs entangling with one another. Soon they were fast asleep, the whole barrack in shock.
It was the next morning while they were eating breakfast when Eren noticed their confused eyes.
"What is everyone staring at?" He looked toward Mikasa and Armin. Mikasa continued eating, uninterested in the topic. Armin looked around and realized what Eren was talking about.
"I have no idea, but I am going to get some more water," Armin said as he was standing up. Eren nodded, shrugged, and continued to eat his food.
Once Armin was filling water, a couple of guys came up to him. He looked up to see Jean, Marco, and Connie.
"Hey Armin, was what that between Eren and Mikasa last night?" Armin raised an eyebrow, confused.
"Jean, he was sleeping at the time," Marco stated.
"Is.. um, Eren and Mikasa dating?!" Connie asked, anxious to hear the answer.
"Eh? No, not that I know of, why?" Armin asked, curious about what happened last night.
"They slept together last night!" Jean said quickly, too quickly. He turned his head, sighed and looked back at Armin. Armin smiled, the three boys surprised at his reaction.
"Well, back in Shiganshima, the houses aren't very big so they normally shared a bed," Armin then continued, "They probably don't think anything of it, it's just second nature to them,"
Jean left, cursing Eren under his breath for having the upperhand.
