Office AU where Eren and Mikasa sit next to each other during tedious board meetings and have thumb wars beneath the table. It's 7-2, and when Eren loses again he becomes visibly frustrated, prompting Erwin to ask Eren if he has a problem with his proposal. Eren stutters, Jean snorts, and Mikasa breaks up their dispute later.
Eren and Mikasa going to a carnival as kids. Eren drags her to each booth, trying to win a huge prize as a gift for her. He only wins a small sphere with a mystery prize inside, feeling dejected as he pops the frosted covering off. It's a small ring (at the time he thinks is genuine) that glitters when you hold it underneath the multicolored lanterns. He wordlessly turns to her and takes her left hand to slide it on her ring finger, both unaware of it's significance. Mikasa smiles sweetly and doesn’t stop looking at it for the rest of the evening.
High school dances neither of them wanted to go to, but ultimately enjoyed because the intimate slow dances and cause of how attractive the other looked. They took pictures in the photo booth, those photos eventually turning into crowded and extremely silly group shots. Mikasa has a copy of them all, and both of them laugh every time they find it.
College AU where Eren and Mikasa are strangers who are assigned as partners for a presentation. Mikasa always comes to the library prepared and on time, while Eren, as you guessed, shows up late and procrastinates. One day as they’re (she’s) working, Eren accidentally knocks over her cup of coffee while enthusiastically telling a story over the phone, caffeine spilling all over her notes. Silently seething, she gathers her things and leaves in the middle of his apology, deciding to complain to the professor first thing in the morning. Later that night as a fan blows over her notebook, Eren comes to her dorm bearing a new cup of coffee and journal, promising to be a better partner. They get a lot of work done in one night, and after cracking jokes and some not-so-subtle flirting, he kisses her.
Eren. Pinning. For. Mikasa. I will never ever get sick of that.
Both of them taking a bubble bath and Eren purposely adding too much soap for extra suds. They both play, Mikasa sculpting bubbles on his head in a hairstyle similar to George Washington, and Eren giving her a long beard and a fluffy mustache.
Mikasa recording Eren after he gets his wisdom teeth taken out. He cries, saying that he won’t be smart now that they stole his wisdom teeth. She comforts him and he instantly feels better, in one sigh telling her that he loves her. And you know who else he loves? Jean. That’s his bestest friend. So nice. So supportive. She snorts at this, making a mental note to use the video as blackmail if need be.
Eren freaking out more than Mikasa when she goes into labor.
The identical looks of disgust Eren and their daughter get when Mikasa tells them she's adding vegetables to their dinner. The conjoined whine of ‘Mikasa’ and ‘Mommy’ are so similar in tone and length all she can do is smile.
