It starts off, like most things do with them, as a joke that both of them take way to seriously. Izuku is on a three day caffeine-driven spiral to figure out how to afford university when he stumbles across it.
“Kacchan I need you to marry me.”
“...why?” And that’s not an immediate no, so Izuku plows on moving into the living room proper so he can properly pace.
“So there’s little to no way I can afford university next semester, even with my two part time jobs and the money I’ve saved up is for emergencies only, and well… in the grand scheme of things I can always take a gap year or two to save up more and apply for more scholarships and grants. But as I am now I’m doing really well in school and if I had to take a year off I might forget something- well maybe not forget but I’m already used to how things are and I just- and I know you’ve also been struggling to pay everything and with this you could get the school to pay your tuition so then you would be able to save up more money and then we could maybe even-“
He’s rambling, he knows this, but when he gets truly stressed Izuku’s mouth tends to have a will of its own. Taking in a deep breath he looks over at Kacchan, who has sat up from his comfortable ball in the one comfy spot on their sofa. His eyes have taken on that same fire that Izuku so admired when they were kids, so hopefully this means he doesn't think that Izuku has finally cracked from the pressure.
“That… that might actually fucking work.” As he says it Kacchan pulls out his phone and starts furiously tapping at the cracked screen, and Izuku takes that as his cue to slum onto the other end of the sofa, dutifully ignoring the springs that dig uncomfortably into his back.
Moments like this make him so glad that he and Kacchan had reconnected at university after having grown so far apart in middle school. Even now neither of them quite know what caused the rift between them, but by the time they were 14 they could barely be in the same room without something breaking. Being assigned roommates their first semester of university should have ended in destruction, but somehow the two of them had come to mutual understanding that first day reunited, and when Izuku went apartment hunting his second year Kacchan was the first number he called without hesitation to see if he wanted to room together again.
A cry of victory brought Izuku back from his musings, as he turned to see his childhood friend grinning sharply at his phone.
“So what do you find out?” Izuku asks, leaning over to look at the other’s screen.
“We’re in fucking luck Deku, looks like the school has no rules about how long the couple was married beforehand and no stipulation about how long they have to be together after the forms are filled out.”
“Really? Huh, guess the school doesn’t keep too close an eye on this kind of situation. I can’t believe this might actually work? What about both people being students?”
“It says here that as long as we get an ordained minister to officiate it and pay the fee at the courthouse where we sign it, we could get married by the end of the week. Fuck yes, and as long as both fill out all our forms before we divorce the school can’t do shit about it. And they got nothing in here banning both people from being students. Goddamn Deku it looks like you’ve got a brain rattling around in that hole in your head after all!”
From there it’s almost stupidly easy to get it all worked out. Katsuki had gotten ordained as a minister in high school because his annoying-ass friends had joked that that was something he couldn’t possibly be good at, as Katsuki will admit only to himself that he had been maybe a bit obsessed with being the best at everything in high school. But jokes on them, because now he can use that power to get himself and Deku married, and now their school has to pay for most of his and Deku’s tuition.
Marrying Deku… if someone had told 14 year old Katsuki that someday he would be marrying that nerd, even just to use a stupid school loophole, he would have laughed in their face. And probably punch them to. But after doing some much needed growing up, and getting his head out of his ass, Katsuki was able to reconnect with the kid he had so unfairly despised.
Neither he nor Deku put much stock into thinking deeply about what they were planning to do, they already lived together and could tolerate each other’s company pretty well. And they were… friends? That’s all marrying was anyway right?
They spend the rest of that day checking every law and tacked on sticky note that they could find, because they might be petty little shits, but they’re petty little shits who did stuff legally.
The next day is spent filling out forms and stopping every once and a while because they happen to look at each other and break down laughing because they're actually doing this. That night they order greasy American takeout, and when Izuku spots a sad little onion ring stuck to the bottom of his burger he has an idea.
With grand movements he dramatically got down on one knee in front of Kacchan, proudly presenting the onion ring as if it were the most precious thing he owned.
“Bakugou Katsuki, love of my life and second biggest All Might fan in the world, will you do the honor of marrying me?”
Kacchan’s eyes widen comically before he snorts loudly and reaches into his sweater pocket to present Izuku with an All Might themed Ring pop candy.
“Thought you’d never ask nerd.”
By next Thursday it’s all sorted out and Bakugou Katsuki and Midorya Izuku are officially married in the eyes of the law, and more importantly in the eyes of their school.
After that life carries on as normal, the next semester starts and both Izuku and Kacchan get to save a pretty penny on their tuitions. By the time everything is filled out the whole marriage situation has become an in joke between the two of them, and both so busy that neither brings up the idea of getting divorced.
Izuku had honestly forgotten that they hadn’t told anyone until he visits his mom a few weeks into the semester. They’re sitting on her much more comfortable sofa when she offhandedly mentions dating and if Izuku has had any time for it.
“No not really, too many projects and to few hours of sleep to really do the whole dating thing.” After a moment he adds on, just as a joke, “besides, I’m married to Kacchan anyway, and he’s not one to share.”
He expects a huff of laughter or even a joking admonishment about Izuku’s choice in men, but the room goes dead silent. As the seconds drag on Izuku is suddenly reminded that he and Kacchan hadn’t told anyone about their marriage.
