I really liked your Popular Kid & Nerd AU, so maybe something else in that universe? :D High school dance, maybe? Or lab partners?
Sabellian loathed placing partners together. They were always horribly chatty, and never got their work done. And they usually kissed over the lab bench. Which was a horrific breach of lab safety code, and, on top of that, disgusting. He was here to teach chemistry, not to watch teenagers "making out".
But the look of sheer hope Anduin Wrynn had on his face when he asked, please, please to be allowed to pair with Wrathion, they'll do the best projects in the whole class, please... he just couldn't bring himself to disappoint the boy.
Not least because he'd hear about it from his own boyfriend, who happened to be Anduin's father, if he didn't keep him happy.
"Just how did you manage to spin this? He never puts romantic partners together. Or... friends, usually.""I just asked him." Anduin beamed.Wrathion narrowed his eyes. "...witchcraft," he muttered, then his face split into a grin.
They did work very well together. Wrathion had all the theoretical knowledge, and although Anduin was clumsy, he was conscientious. Their practicals produced perfect results; their write-ups, dictated by Wrathion and written down in Anduin's careful handwriting, were as diligent as they were technically perfect. And Sabellian couldn't even get them on safety violations - Anduin's cautious nature meant he corrected the mistakes Wrathion usually made with those things.
It drove Sabellian up the wall.
And that made Wrathion very amused indeed.
