Chapter Text
It’s a hot mid-summer day in Fukuoka Japan. The temperature no doubt in the high 90s as the sun shines blindingly in the vast blue sky overhead, not a cloud in sight. And if one were at the beach, this would be the most opportune weather. Bright sunshine accompanied by the cool waves, the perfect balance.
But for Katsuki Bakugo, who was nowhere near the beach, being in this type of weather was the worst.
It was the start of a new week, and Katsuki’s mood was already irked from the simple fact of it being Monday. His internal alarm clock deciding to falter this morning, making him wake up later than normal and rush to get to school. Just narrowly missing the bell.
In the UA building, the AC had already been malfunctioning since the beginning of the year. Normally, with how proactive UA is, they’d have fixed the issue in winter. When the AC working didn’t matter.
But between an infiltrated attack on the school, a kidnapping and trafficking incident involving a child, and the capture and arrest of one infamous ‘Chisaki Overhaul’. It was safe to say the school had other, bigger, priorities at hand.
So, when it’s 2nd period, and the AC abruptly malfunctions, turning the classroom into a full functioning furnace in less than half an hour. Bakugo thinks up a plethora of colorful curses aimed at Chisaki in his mind.
The blonde silently wishing for Chisaki to be writhing in pain somewhere with no one caring to help.
By 4th period, even the stoic Aizawa himself had begun to show signs of discomfort. Fanning himself with a clipboard as he scowls tiredly at the whiteboard. Too drained to continue writing, no thanks to the heat and his students’ noisy complaints. (Kaminari’s in particular.)
And it takes everything in Bakugo to not freak out.
Ever since he had developed his quirk at the young age of four, Katsuki had been especially susceptible to heat. Any sign of sweat, that wasn’t actively trying to be produced by Bakugo, had the potential to spell out something dangerous.
Glancing down at his Nitroglycerin drenched uniform, both his shirt and slacks wet from constantly wiping his palms on them. And towards the end, even that didn’t seem to help.
Bakugo curled up against his desk, panting heavily as he clenches his fists closed, praying for the AC to kick back on. Or for his palms to stop fucking sweating so much.
“Kacchan, are you okay?” A voice asks behind him, concerned. And Bakugo has to physically bite his tongue to prevent himself from whining in response. His body and mind in a state of vulnerability. And the sudden exposure to Midoriya’s deep, soothing voice was not helping.
When Bakugo doesn’t respond, Midoriya frowns. Wiping the sweat from his own forehead momentarily as he stares at Bakugo’s hunched form. His bright green eyes worried.
“Sensei!” Izuku’s abruptly calls out, raising his hand.
And Bakugo cringes. Hoping to God that Izuku wouldn’t bring any unwanted attention to him.
Oh fuck, please shut the fuck up Deku
“Since we’re unable to do classwork in this condition, is it alright if we head to the training grounds?” Midoriya asks. And Katsuki can feel his body instantly relax, some of the previous tension bleeding out from where it was stored in his shoulders and neck. And Aizawa takes little time to ponder over the suggestion before agreeing.
A shout of joy escapes Kaminari’s lips as all the students move to hurriedly file out of the classroom. And Bakugo, for once, agrees with the spark-plugs sentiment.
Being one of the last to leave, Bakugo leans against the sliding doorframe. Holding back a few moments just in case his quirk activates, so there’s no chance of harming someone on accident.
Katsuki distinctively knows that there’s people behind him. But they’re silent for the most part. Walking in leisurely peace, and Bakugo’s at least grateful that it wasn’t one of his noisier classmates following behind him.
Humming softly, Bakugo notices how his body begins to slowly cool down as they walk through the halls, and it’s almost comical to Bakugo. A sneer pasted on his lips.
Of course, the shitty AC only stopped working for us and no one else.
The next time I see that principal rat bastard I’ll make him wish for death!
Nearing the school training grounds, Bakugo sees all his classmates gathered outside by the door. Aizawa standing off to the side with his arms folded as he takes head count. And there’s a sudden, abrupt shout, followed by the hurried footsteps of one familiar brown-haired sub. The distinct smell of bubblegum sticking to her clothes.
“Izuku! Shouto! I was wondering where you guys were.” She says, her high energy never seeming to cease as she bounces towards them. And as she nears, she subtly brushes past Bakugo. Neither of them acknowledging each other’s existence.
Just the way Bakugo liked it.
“Ah, Shouto had ended up falling asleep in the classroom so I stayed behind to wake him up.” Izuku responds, his tone friendly. And Katsuki glances over his shoulder at the reveal of the two ‘mysterious’ figures that had been walking behind him. Izuku’s hand braced on the back of his neck, as Uraraka stands close to them, giggling.
And as if he could sense it, Izuku lifts his head up momentarily, catching Bakugo’s gaze. The eye contact stirs something foreign inside of the blonde’s chest, and almost instinctively he scowls. Turning away with a huff, before moving to join the other students outside.
Those were the events that led up to Bakugo’s current predicament.
For the training session, Aizawa had decided on split teams of three. Two groups were to face off against one another in a random training ground of his choice. It’s a showdown type spar, winner being the team left standing. Quirks were allowed, but nothing that could potentially harm the other person.
And at the time, when Bakugo had first listened to Aizawa explain the rules, it had seemed easy. Right up his alley truthfully, since Bakugo was better suited in combat during showdowns than stealth during mission training.
But, as if Katsuki hadn’t exhausted enough patience as is. It was just his luck to not only get assigned to the only training ground that was located outside, under the sweltering hot sun, but to also be paired in a team with shit Deku and even shittier half-and-half.
Bakugo could already sense the jealous stares from his sub classmates.
Both Izuku and Shouto had powerful quirks, and were prime Doms. But most noticeably, both of them were equally a pain in Katsuki’s ass.
“Kacchan, you’re overheating. You should fall back.” Midoriya implores, crouched down by Bakugo’s feet behind a large haphazardly placed piece of metal. Meant to look like fallen debris.
Since the round started, Bakugo had made it his absolute mission to not be anywhere near his teammates. Trusting his ability to hold off on his own should he come across the other team.
It seems neither Izuku, nor Shouto, shared the same objective. Since any place Bakugo would move too, they would follow close behind.
Like Bakugo had said,
pains in his fucking ass.
“Shut the fuck up, Deku. Don’t tell me what to do.”
Bakugo huffs, a line of sweat cascading from the side of his temple all the way down to the baseline of his throat. Soaking the collar of his hero suit.
And he peers around the piece of metal, using it as a cover in hopes to spot the enemy team. His eyes scouring the plane before turning back around. His chest rising and falling in fast sequence as he pants. And off to the side, he could feel bastard teammate #2 staring at him.
“What? You got something to say?” Bakugo growls. Shifting down to a squat, he turns his head to look at Shoto. His red eyes glaring menacingly into the other boys heterochromic ones.
And all too suddenly, does Bakugo lose his fire.
Shouto is sat on the ground. His back braced against a decent sized rock, his right knee is bent and on top of it he rests his arm. Using his quirk to cool down his body.
Sitting in that position, Shouto easily feigning leisure, as white and red strands of hair whip gracefully in the wind.
But none of that was what caused Bakugo to stop his pre-mature rage.
It was Shouto’s eyes.
Pale grey and fire red burns into Katsuki, Shouto’s eyes seemingly glowing. And his lips are set into a hard line, his jaw clenched. His face holding an impassive expression as he sets Katsuki with a predatory like stare. Stark silent.
And once again, Katsuki feels something unknown stirring inside of him as he holds Shouto’s gaze. And he knows he shouldn’t break eye contact, that by looking away, he’s basically claiming defeat in their silent exchange.
But the longer he stares, the more that feeling grows inside of him. And all too quickly does he realize that a part of him wants to break eye contact.
Katsuki wanted to be the prey in this situation.
“Kacchan?” Izuku interrupts from next to him, freeing Bakugo from his horrid revelation. And he uses Midoriya as an excuse to look away. His heart beating in his chest.
There’s a loud bang from somewhere in the distance, and it catches Bakugo off guard. His body jolting in panic, and Izuku shifts slightly closer to him. Moving to shield part of Katsuki’s body with his own tall muscular one. And Bakugo stutters in a breath.
The smell of Izuku’s familiar body wash followed up with another more masculine scent fills Bakugo’s nose. And it sends shivers up his spine. His body relaxing for a brief millisecond before he tenses. Set on the defensive despite no enemy being around.
Uncaring of giving away their position, Bakugo aims two gauntlets at the ground beneath him before igniting a large explosion. Propelling himself up into the air, his mind a mess.
What the fuck just happened?
