Arranged Marriage; Forgotten First Meeting
To me this sounds like two princes who have a very drunken hookup in college, both too drunk to recognize each other, and then stumble out the next morning without looking their silent shame in the face.
A few years later they’re out of college, they’ve stopped partying (mostly), they’re respectable, it’s time for them to do their princely duties and get married. For the good of their countries and solidifying old fashioned alliances and whatnot. Neither of them is particularly thrilled about it because rumor has it that Stiles guy is kind of a weirdo, and Prince Derek has one hell of a stick up his ass.
But they’re adults, they’ve known this was coming, they follow each other on Instagram (though Derek has posted all of one picture, that was clearly posted for him), they can handle it.
They finally meet in person, officially, with their parents and diplomats and a trusted photographer in the room, and there’s…something about this guy. Stiles narrows his eyes over their handshake that’s been going on too long, trying to place why he seems so familiar; Derek raises his eyebrows at what he interprets to be blatant dislike, and things are off to a rocky start.
There are formal brunches during which Stiles practically glares at the guy, because when has he met him before? Somehow he knows him!
Stiles plays the piano, because he’s a well rounded prince, but Derek can’t even focus on the music because he can’t stop watching his fingers. There’s something familiar about them. He has some distant, fuzzy memory of those fingers—and for some reason they’re a turn on?
They’re at a diplomatic soiree, keeping close to each other for appearance and because they really should get to know each other, when a server approaches them with a tray of crystal champagne flutes filled with the finest bubbly. Stiles shakes his head as Derek holds up a polite hand, and the server moves on.
“Bad experience in college,” Stiles says, and Derek just nods. Neither can remember the details, but there were two bottles of stolen champagne finished off on a rooftop under the stars.
It isn’t until much later, maybe months, maybe after the wedding that they realize why they know each other. Maybe Derek takes off his shirt for a quick swim, or Stiles spills something on his dress shirt and has to borrow one and starts unbuttoning while Derek’s standing right there. Maybe it’s Derek’s abs Stiles remembers licking, or a particular mole Derek has a weird memory of biting a massive hickey onto while drunkenly advising Stiles get it checked for melanoma.
Either way, there’s a moment realization where they stand there, gaping stupidly, totally blindsided as that night slowly filters back into their minds in bits and pieces, and then there’s probably more ab licking and mole biting and Derek’s still weirdly concerned about melanoma.
