FUCK tumblr, I didn't want to rewrite the old rokitodo/frostflame post so here have some more general hcs
Fire is Roki, Ice is Todo. Shouto is Todoroki in general, without being split in half. Shouto is not mentioned in this here post but it's important enough to mention.
They're both EXTREMELY sensitive to the opposite temperature
Cuddles are either disgustingly soft and gentle or just a nightmare to attempt
Todo is the small spoon because Roki is warm and more open about wanting physical contact between the both of them
Roki is much more expressive than Todo (cough cough Todo is Roki's only filter) thus there's a lot of affectionate stuff he does which shocks Todo AND everyone who's ever met Shouto
Todo still loves cold soba, but Roki is pretty much repelled by it. He's sensitive to cold, as previously mentioned, so eating cold soba is out of the picture before it's even brought up.
They're not big into PDA, but sometimes Kaminari or Kirishima catch them holding hands or gazing into each other's eyes like the lovestruck idiots they are.
Roki's sight is frankly terrible, so he mostly relies on his other senses and Todo if it comes to it.
They can't play the "who's who?" game and Roki loses sleep over this fact
Roki and Bakugou get along... a lot more than they should. Todo's a little worried about how similar the two are, considering he and Roki are supposed to be the same person.
The easiest way to describe the difference between them is that Todo acts more like pre-sports festival Shouto. He's more passive in his anger, cold and intimidating when he wants to be. Sometimes he'll start frosting things when he's upset or surprised, which he claims he doesnt do but Roki has had it happen to him when he hugged Todo at the wrong time
Roki, on the other hand, is a lot more loud and frustrated in general. Todo will sometimes say that Roki runs on pure spite, but they know it's not true. Roki's comforted by Todo's presence, and thus a lot more open when it comes to talking about himself around Todo. He's a dork and has tried to get Todo in on his conspiracies to no avail
Once, Kaminari talked with Roki. Considering that Todo hoards the braincells, Roki ends up blabbering about anything and everything. This leads to an odd sort of friendship between him and Kaminari. Kami honestly just thinks it's hilarious and also kinda cute
Todo will sometimes go mute when he's especially upset. It's the complete opposite with Roki, as he talks his mouth off when he's distressed.
They try to match outfits, but with the white-red grey-blue thing they have going on, it's hard to find colour combos that don't clash. One day, Roki gives up and just slaps 'He's my ex boyfriend --->' '<--- Stop saying that. We're married.' shirts on the both of them
Predictably, Todo puts up a fight about it but he's won over by Roki's subtle puppy dog eyes and whining. 1-A freaks out over it, as they should. Sero has the guts to ask Todo if they're actually together and Todo just stares down at him.
you know what's better than one idiot? TWO IDIOTS
Todo hoards the braincells most of the time, but Roki steals one (1) and he uses to figure out if All Might and Midoriya are related.
They're both extremely traumatised and neither have a good sense of boundaries, which leads to many occasions where Todo frosts Roki's mouth closed before he can say anything insensitive or rude, as you do.
Roki still sets himself on fire when he blushes, but now his whole goddamn body is on fire.
This sets off a chain reaction that eventually causes a bunch of people to flirt with him because they want him to set himself on fire, apparently.
Todo, being the vaguely possessive little shit he is, decides the best way to counter this is to flirt with anyone who tries to flirt with Roki.
Talking to those two is always weird, but espcially so if you're trying to hit on Roki because Roki's just progressively heating up more and Todo is leaning on his shoulder, aggressively flirting back with you.
Because of this, no one catches onto the fact they're dating until Roki kisses Todo on the lips in the common room. Roki does it because he's impulsive and wants to PDA, a rare occurance in and of itself
They share daddy and mommy issues, which sounds extremely chaotic. It is.
Todo takes Shouto's approach to it, passive aggressively slurping his noodles and all in all just giving his father the cold shoulder.
Now Roki? Roki learns from Natsuo a little more than he should. He gets Todo to help him write a long, long list about all the ways Endeavour screwed up their life. Instead of saying it all at once, Roki writes one reason on a piece of paper and leaves it for Endeavour to find every. single. day.
Roki felt a bit off once so he asked Todo to just pick another reason off their list and do it for him. Instead, Todo wrote "I'm dating myself now. We will overthrow you." on it.
Roki really hates that half his face is scar, so Todo will kiss part of his scar before bed every night.
Their hair are different textures, so when Roki runs a hand through Todo's hair one day he simply leans back and goes "ew"
Roki's hair is a little bit fluffier and messier than Todo's. Todo's is flat but very, VERY silky. Roki is salty that his hair isn't like Todo's.
Neither of them like coffee or anything with too much caffeine. The Bakusquad get the two of them to drink a little too much coffee. Roki reacts as expected, filter completely gone and near (near, NEAR!!) hyper. Todo doesn't go batshit or act hyper like Roki, but he doesn't sleep a wink that night.
That's it for now, I have more for the future if yall want it
