Urrr, does it have to be an established AU? Because if not, how about Kurofai Grad School AU? (where they're both grouchy, stressed, and sleep deprived and keep running into each other in the building's atrium...)
Thereâs like so many things they could possibly study for grad school //handwaves
1. Both of them were complete biology nerds growing up. Kurogane specializes in zoology while Fai in biochemistry.
2. The labs might as well be open 24/7 to the grad students. Now and then they run into each other at the department building at 2 in the morning working hastily on their research and experiments. Week by week, their schedules âsomehowâ align more and more. Maybe itâs because they think the other are really attractive. Fai wonders how Kurogane fits in time to workout and have such a hot body. Kurogane desperately thinks itâs his sleepiness fooling him to see Fai as a truly handsome man.
3. They cuss in agreement that the scientific method they learned for so long in school, until their undergraduate years, was oversimplified and full of lies.
4. They also cuss/confide in each other over the baloney students in their classes give them. Fai had never been so stern to anyone until he became a TA (among the bajillion of duties being a grad student entailedâŚalso pays off little of his growing student debt). Kurogane recalled the times he gave some of his TAs a hard time in his undergrad years, and felt pangs of remorse. Kurogane also gives hell when his and Faiâs students spread rumors that they are dating. Theyâve been for at least six months.
5. There is no doubt Fai is brilliant in his field of study. But on his first day (of many) presenting and defending his dissertation to the faculty panel, Fai was a nervous wreck. Kurogane, in spite of being grumpy and running on little sleep and lots of caffeine consumption, is Faiâs #1 cheerleader and gives his fiance lots of cuddles in bed.
