They were fighting, again. And once again, it was over your attention. Eren had given you a pen and Jean had got mad. It was petty and childish.

"It was just a pen, bastard!" Eren yelled, grabbing Jeans shirt and shoving him to the wall.

"Just a pen!? It was way more than a pen! If he/she wanted a pen, he/she would've asked me for one!" Jean tried hitting Eren but missed.

"I can't believe you're crying over a pen!" Eren snickered, going in to punch Jean once again.
