Zeke Yeager, your boyfriend. He’s a few years older than you, starting pitcher for the Marley University Warriors, and one of the smartest guys you know.

Eren, one of your best friends. You met him at the start of this school year in your econ class, and he quickly brought you into his friend group.

But how were you supposed to know the two were brothers? Zeke has mentioned his little brother before but gave no details, and Eren never even brought up having an older brother! Plus, Eren never mentioned his last name; it never seemed important enough to bring up.

And that’s how you found yourself here: snuggled up in your boyfriend’s arms on his couch with some shitty movie playing, him shirtless and you in some comfy tank top you pulled out of his closet, when Eren walks in with a bewildered look on his face.

“What the hell are you doing with my brother?”
