Diggory and Marolmar are getting arranged married while both actually being in love with Nikignik, otherwise it wouldn't be as arranged; in my head it's some sort of a political union between human and Indie-adjacent but less. well. indescribable factions (fae? my go-to for making god-like characters more "down to earth" so to speak is fae). it's not pretty. they put on a facade of at least liking each other during their wedding, both being nice to guests and reporters through gritted teeth, and at some point during the party both sneak away from the crowd to get some fresh air. Marolmar is outside the venue touching grass and trying to make his breakdown into a quiet one, and Diggory is hiding in a bathroom staring in a mirror with a blank face and contemplating their unfortunate fate. Nikignik is the first to notice their absence and follows Diggory first; there's a heartfelt confession slash vent scene and Nikignik tries to convince Diggory to go find Marolmar with him but isn't successful, so he goes on his own. cue a second confession slash vent scene, where Marolmar finally loses his shit and starts crying. thankfully there's only him and Nik outside, no other witnesses. Nikignik's really confused because from his point of view what Marolmar and Diggory thought of as advances or flirting were just signs of friendship and tbh he doesn't think he's in either of their leagues and doesn't think of himself as worthy of attention and love anyway, but now is not the time to process his own feelings, he has to get them both to calm down unless he wants them to be at each other's throats and compromise whatever relationship he has with the two, and Nikignik really REALLY doesn't want to lose either as a friend (though "losing" them on technicality by becoming a _boy_friend does sound good). of course it's not mended in one night, on the wedding day Nikignik barely manages to reconcile them enough to keep up the newlyweds act, but through countless times hanging out together, a lot of talking things through and clearing up the misunderstandings Marolmar and Diggory somehow end up liking, and then loving each other: they are both passionate about ecology, though Diggory is more of a peaceful protest and do what you can kinda guy* while Marolmar is always one bad day away from straight up violence against people in charge; they are both artistic, Diggory a poet dabbling in music and Marolmar a painter; they both enjoy their alone time and orefer to show affection by just being next to their loved ones and quietly doing their own thing. Nikignik wipes away the sweat from his forehead and kinda bitterly thinks that he has never been good at helping others' relationships but at least he's better at it than at making his own... and that's when Marolmar and Diggory conspire "against" him and ask him out. together. as a throuple, maybe, probably, if Nik is okay with that and would want either of them. if he wouldn't then no worries, they're all adults here, they can stay friends; if he prefers one to the other it's also okay, neither is stupid enough to break off a friendship with him over that, and they are quite comfortable with the prospect of their de-jure spouse dating their friend, if that means they still get to hang out all together sometimes. Nikignik is in absolute shock but agrees immediately, no questions asked. happy end yay!!
