I think the funniest HR AU stuck in my head is one where there is Human Ilya and Non-human Shane, and it isn't until they have a huge fight that Shane realizes that Ilya is completely unaware that he is dating a Creature and not a Regular Man
He just, kind of assumed that Ilya had figured it out. He came out as gay and got laughed at! And it's way more reasonable that he could be bisexual than fully human. And if Ilya didn't know then why was he constantly doing little Mr Man teasing comments for the past few years?
Just like, Selkie!Shane who knows he smells like salt all the time, and eats so much fish, who has made comments about how skating is the closest you can feel to swimming in the open ocean on land, who showed Ilya his pelt?? They had a romantic night where they made out on top of Shane's pelt and Ilya assured him that he liked that Shane chose him???
Meanwhile Ilya feels fucking insane. How was he supposed to guess that Hollander was fucking magic? He thought Shane was within the normal human spectrum of weird! He didn't know magic existed! He's never even heard of seal people, why would he question a fur coat?? What next, the babayka he was afraid of as a child is going to be a neighbour?
There's something that just tickles me about Shane "but You know me better than I know myself" Hollander VS Ilya "I didn't know fucking monsters were real Shane!" Rozanov.
