Eren had no fucking clue why he was absolutely seething when he saw you chatting up a storm with another guy at this party.

Eren knew he had no right to do or say anything about it. You guys were merely friends with benefits until one of you guys call it off. Eren didn’t want to admit it but he was scared you’d call it quits one day.

He was scared you’d go find some new guy, leaving Eren in the dust. He never felt this way when he dated Mikasa. So why was his chest aching this much? It’s not like you were flirting with him!

You laughed, touching the guys chest as he said a stupid joke, Eren assumed. Oh yeah, you were definitely flirting.

Without much thought, Eren chugged the last bit of his drink and crushed it, tossing it to the nearest trash can and stormed over to the both of you. To be honest, Eren wasn’t thinking, rationally, he’d just play it off and flirt with other girls. But he just couldn’t handle it. Not today.

It’s the alcohol, Eren justified as he yanked you away from the guy. “What do you think you’re doing with my girl?” Eren hissed, wrapping his hand around your waist, tugging you closer to his chest.

You looked up at Eren with wide eyes and confusion. But Eren didn’t meet your gaze, instead he shoved the guy and dragged you away.

You guys are friends, that’s why he’s acting this way. It’s not like he’s into you or whatever. He just wants you to be with someone good. Someone who will treat you better. Make you feel good. Make you feel so good.
