[Modern AU actually]

You met through Eren, but it seemed like Zeke initially blamed himself for falling in love with his brother's best friend, after all, he was 6 years older than you..

As time passed and during the events that your friendship team organized, Zeke also started attending these events because of his interest in you, and as expected, thanks to his charisma, romance began between you.

Four years have passed and you have just been married for a year. Today he had a tough day at work, one of his clients was a girl who had been severely assaulted, which triggered Zeke's detective instincts. He got to work and found the criminals and defendants, then finished the job with a professional beating and collecting evidence and handing it over to the authorities.

Now, at 11:30, he was driving back to his warm, cozy home, and as he drove down the dark street and glanced at the street behind him in the rearview mirror, he allowed himself to forget the stress of the day by starting to think about his lovely wife. You were probably worried because he was several hours late and hadn't returned any of your calls.
