the thing about harry du bois and kim kitsuragi is that they fit one another, in a way that kind of goes beyond normal fitting
like, harry is A Lot. this is known. he is Too Much for a lot of people (dora included), but he is not Too Much for kim. Kim fucking eats that shit up. every time harry centers him or puts the spotlight on him, i expected him to be embarrassed and he puts on a show of embarrassment but if you have the good empathy you know, you know, that he's ABSOLUTELY LOVING IT, he's just not very demonstrative about it
he loves it when harry gives him a shoutout on his favorite radio station
he loves it when harry dedicates a karaoke song to him
he's a little less enthused about getting dragged out onto the dance floor but that's more because of his history as a juvie cop than anything about harry's attention being on him. this is a man who has always been sidelined his whole life, who has had to walk a tightrope to make sure he was never showing too much of himself and for whom the idea of attracting attention has typically meant attracting negative attention
and then he has harry's Whole Attention and suddenly all of it's positive and focused on him.
harry thinks that love at first sight is what happened when he met dora
but love at first sight is ACTUALLY what happened when he met kim
it just takes him a lot longer to realize it
(this is why i'm not very good at reading/writing slowburn in this fandom. while my caveat is that as with any read, esp in a fandom where the player has so many ways to play the MC, this is mega YMMV, i just cannot envision any scenario where these two chucklefucks aren't basically married by the time the tribunal is over. the only kind of slowburn is the kind where it takes them both six months to actually notice they've been dating since they met.)
