Chapter Text
Right. Uppercut. Pin.
Easy.
Katsuki had everything planned out before the whistle even blew. This training session was in the bag for him. Iida looked ready. He was posted in a defensive stance across the mat. Though they’d only been in class together a few weeks, Katsuki could already tell Iida was particularly weak in training because of his morals. He was a poor match for Katsuki, who fought dirty, which was probably the precise reason they had been paired together.
“Ready,” Aizawa pulled the whistle to his mouth before blowing in sharply. The second the sound breached the air around them, both were darting towards each other.
Right. The plan was in motion, only Katsuki hadn’t accounted for Iida sliding and taking him out by the leg. Whatever , easy recovery. Katsuki pounced back up, using Iida’s low position to land a kick on the other. Practically unfazed, Iida bounced off the floor. He went straight for Katsuki’s ribs with a punch. Fists and feet flew back and forth as the fight went on. They traversed the small ring, both ending up on the floor multiple times.
After another punch to the gut, Katsuki was starting to limp around a bit. He was struggling to manage his own strategizing with monitoring Iida’s moves. This should've been easy, but Iida was nearly a foot taller than him and probably fifty pounds heavier. Katsuki threw an uncalculated blow in frustration at the circumstance. At that, Iida took advantage and grabbed the arm he had tried to punch with, using it to throw Katsuki on the ground and pin him down. The pain of whatever had happened to his shoulder in the moment was merely a sting compared to all the other pain his body was in, but something had definitely happened to it.
“Iida wins,” Aizawa declared, though he couldn’t have sounded more bored.
“Why the hell can’t we use quirks? I’d have gotten that bastard in ten seconds if this was actually fair!” Katsuki shouted from the ground. Promptly, Iida tried to extend a hand to help the other. Katsuki only shoved it away. He tried to pull himself up with his right arm, but it gave in the second he put pressure on it. A grunt left his mouth as his shoulder crunched for the second time in a minute.
“Bakugou, there are many reasons why you can’t always rely on quirk use in the field. It’s important to be able to navigate combat without one.” Aizawa had already given the same spiel before the fights and Katsuki was less than interested in hearing it again. Using his good shoulder, he pushed himself up and started stomping over to the bench.
He was stopped by a frustrated Aizawa grabbing his arm, “What happens when you take out the guards of a base with that flashy quirk of yours and the leader gets out before you can even get to them?”
“I’ll get their ass too,” Katsuki grunted, cocky as ever.
“You’ll learn eventually,” Aizawa grumbled, “In the meantime, go see Recovery Girl about your shoulder.” Katsuki shot him an ‘I’m fine’ look, but Aizawa started filling out the pass anyway. At least he wouldn’t have to watch anymore of the dumb quirkless fights; nothing was interesting about a bunch of sweaty teenagers brawling. Begrudgingly, he made his way to the nurses office, wincing in pain the whole time.
The nurses office was typically a busy place at such an unconventional school, but at the moment it was absolutely packed. There were students in practically every bed. Quite frankly, Katsuki thought they all looked like shit. They were adorned in their eccentric hero costumes, however the fabric of each was ripped and dirty. IVs were running next to nearly each patient and bandages were strewn across all of them. Luckily, most were already asleep and recuperating from Recovery Girl’s work. Katsuki would likely only need a light nap, but he’d probably end up like them in a minute or two.
At the desk sat a very disgruntled looking general studies student typing furiously. Katsuki handed over his pass without saying a word and sat down. At least there was no one in the waiting area; he probably wouldn’t be sitting in pain for too long by his own calculation. While he waited, Katsuki stared at his feet, analyzing each move he’d made in the fight. He should’ve stayed back and waited for Iida to make the first move so he could react better, or used Iida’s body weight against him by throwing him to the ground.
“Katsuki,” A sweet voice exclaimed across the waiting room. It wasn’t Recovery Girl’s grainy but sugary tone; this was someone completely different. Katsuki froze, looking up to see an unfamiliar, but incredibly cute boy. He was tall and built, scrubs taut over his biceps. The face that matched was completely different from his rugged body; he had a soft smile and wide eyes, all complimented by light freckles and messy hair that was… green? Katsuki could have sat in that waiting room and stared at him until he bled out. Not that he was that seriously injured… but, god that guy was cute.
“Katsuki?” The boy said again. While Katsuki had been staring at him, the boy had somehow gotten several steps closer.
“Do you need help getting up?” The guy asked, holding out a hand.
“No,” Katsuki finally grunted, pulling himself to his feet, “my legs are fine.”
The boy giggled nervously before continuing, “In that case you can just follow me, Katsuki.” God, he had to stop saying Katsuki’s name. His face was getting redder by the second; it just sounded so satisfyingly sweet coming out of the strange person’s mouth. Katsuki had made one trip to the nurse’s office so far, despite sending several of his classmates to the place. Whoever was leading him back had not been present at the time.
“How do you know my name?” Katsuki deadpanned, trying to get his brain together.
“It says on your pass,” The boy scratched his head and let out the same nervous giggle. When he brought his hand up, his scrubs traced across his back muscles in a way that revealed every one to Katsuki. He wasn’t sure if looking at them or that freckled face was worse.
They made their way to one of the open beds in the back corner. Dumbfounded at the whole situation, Katsuki just stood like an idiot, staring at the doctor’s back muscles contort under his uniform as he fiddled with the curtain.
“You can have a seat,” The boy gestured to the bed.
“Yeah I know,” Katsuki blurted, settling in, “Who are you by the way?”
“Sorry, my name is Midoriya,” He looked uneasy, like he knew he should've introduced himself by now, “Izuku Midoriya. You can call me whatever you’d like.”
“Doctor Midoriya?” Katsuki asked, raising an eyebrow in suspicion. This guy looked too young and nervous to be a doctor.
“Technically no. I’m still a student, so I guess Izuku is just fine then.”
“Why the hell is a student taking care of me?” Katsuki blurted. Izuku only grew more flustered, the clipboard in his hand shaking a bit.
“Well technically I have all the qualifications of an official doctor, but I’m 17 so I’m still a student doctor. Sorry, I don’t usually see patients by myself,”
“I can tell,” Katsuki said wryly.
“Shit, sorry,” Izuku started panicking, “I shouldn’t curse in front of you. Sorry… again.”
“You’re a third year?” Katsuki shot, grilling the credentials of the seventeen year old boy about to take care of him at the most prestigious school in Japan. Izuku nodded weakly.
“Can I start over?” He asked, reaching a shaky hand out to Katsuki. Using his good arm, Katsuki shook the sweaty thing with a confident grasp. That seemed to shoot a bit of courage into Izuku who took a deep breath before speaking.
“My name is Izuku Midoriya. I’m a third year general studies student with a focus in Hero Medicine. I’m Recovery Girl's student aid. She only ever takes on one third year at a time, so that means I’m the most qualified,” Katsuki gave him an approving smile, “UA has a special hero medicine track where general studies students can take college level medical course from their first year at an accelerated pace, meaning I have almost all the credentials of a college educated doctor and am qualified to take care of you.”
“You sound like you know your shit then,” Katsuki replied.
“Right,” Izuku sounded a bit like he was convincing himself of it too at the moment, “Now it’s my turn to ask you the questions.”
“Get on with it then.”
“Alright. You’re Katsuki Bakugo, first year hero course?” He confirmed, looking down at the clipboard that Katsuki assumed had some sort of chart about him.
“Yep.”
“When is your birthday?”
“April 20th,” Izuku was still shaking a bit; his nerves made his eyes stick straight at the clipboard rather than Katsuki. Taking advantage of this, Katsuki took his time to stare at Izuku while he mumbled the information back.
“15 years old?” Izuku’s eyes flicked up.
“Yeah?”
“You just…” Izuku mused looking over Katsuki’s face, “look a little more mature I guess.” He looked down just in time to hopefully miss the red on Katsuki’s face. He’d probably have to say he was at the nurse for a fever to excuse it at this point.
“Anyways, what's your quirk?”
“Explosion,” Katsuki grinned, proud as always.
“What does that do?” Izuku asked, scribbling the answer on the page.
“Wanna find out?” Katsuki raised his palm sadistically.
“No no no,” Izuku panicked, using his hand to gesture for Katsuki to put his own down, “I’m sure it’s pretty straightforward.” Katsuki shrugged in agreement.
“Okay, and what are you here for?”
“Fucked up my shoulder during training,”
“Ouch,” Izuku stepped closer, taking a shaky breath before his next question, “Do you mind removing your shirt?” Katsuki nearly laughed at the clinical way he said it even though it was appropriate for the setting. He started to peel it up with one arm, not upset at all that Izuku would have to see his chest. About halfway up, he grunted, struggling to pull off the garment with one arm.
Katsuki swore he heard Izuku take in a sharp breath as he revealed his abs, “Do you need help?”
Unfortunately for Katsuki, he absolutely did. He probably looked so stupid in front of this hot third year kind-of-doctor guy, not even able to take his own shirt off.
“Mm, yeah,” He grumbled.
“Alright… um,” Izuku took a second before landing on how he wanted to do this, “if you could lift your good arm. I’m going to…” Katsuki watched as he cutely stuck his tongue out just a little to focus. Inhaling deeply, Katsuki felt the fabric caress his skin. This was entirely clinical, he reminded himself over and over. The doctor slowly worked the shirt over Katsuki’s good arm and head until it was left sagging over his messed up shoulder.
“Tell me if this hurts, okay?” Katsuki nodded and Izuku promptly went to work removing the garment as slowly as possible. Lucky for Katsuki, it caught on his large bicep for a second. He watched as Izuku bit his lip just a little before continuing.
“Yeah that looks pretty dislocated,” Izuku blurted. Katsuki snorted at the less than professional diagnosis. When he looked, he too realized exactly how not in the right place his shoulder was.
“How the fuck did I not notice that?” Katsuki uttered, a bit in shock.
Izuku laughed, not seeming to realize Katsuki was entirely serious, “It’s okay, the pain tends to get to people.”
Izuku kept talking, distracting Katsuki a bit from his distress, “At the moment you have two options for a dislocated shoulder.” He was still smiling wide, which somehow managed to put Katsuki a bit at ease. It probably helped that he had an amazing smile, but Katsuki just enjoyed the idea of his doctor not being so nervous anymore.
“And they are?”
“Right, well… between you and me there was a huge incident with third year hero course students today, so Recovery Girl has her hands full,” He whispered a bit trying to keep the information confined to their curtained area. Katsuki felt his chest twinge at the boy he just met feeling comfortable enough to share what seemed like a secret.
“Your first option is waiting a few hours for her to do it painlessly,” He trailed off before timidly revealing the latter, “or I can pop it back in right now.”
“I’m assuming that’s going to hurt?”
“Like hell,” Izuku nodded.
“Alright get it over with,” Katsuki shrugged, sitting up in preparation.
“Seriously?” Izuku asked, full of surprise.
“Duh.”
Izuku smirked, looking Katsuki up and down in an incredibly non clinical way, “You’re tough Katsuki.” His eyes grazed Katsuki’s and held their attention together for just a second, before he quickly pulled the curtain back.
“I’ll be right back,” He smiled before rushing off, leaving Katsuki alone to analyze every second of what had just happened. Tough. Tough? Katsuki didn’t know it until that very moment, but tough was the only thing he ever wanted to be called, especially from Izuku’s sweet mouth.
After a quick trip, Izuku returned and pulled on a pair of blue latex gloves. They were bittersweet for Katsuki because while they did look incredibly hot, Katsuki also desperately wanted those thick hands directly on him.
Stop. Stop. STOP.
This was a doctor for god's sake. Maybe he was hot and only two years older than Katsuki, but he was still in fact a professional just trying to do his job. Katsuki doubted he was even special. Half of his classmates had probably already fallen for this guy; he was just another first year who had been struck by the sparkle in those big green eyes.
“I’m going to perform what’s called a closed reduction on your shoulder,” Izuku explained, “or like I said earlier… I’m just gonna pop it back in.”
“Get to it then doc,” Katsuki bounced up, spinning his back to Izuku.
Izuku laughed a bit, “Actually, we usually do this part lying down.”
“Right,” Katsuki slid back down onto the bed in embarrassment. Cold latex met his skin, massaging around his tender injury. Izuku’s hands were careful and calculated, despite how large they were. He was delicate within his movements, a clear sign of his qualification.
Katsuki squeezed his eyes shut in anticipation. As a hero hopeful, he was no stranger to pain. Fighting and injuries had been a part of the process ever since he started training on his own as a kid, but what he couldn’t stand was when he knew the pain was coming. It was easy to fight through cuts and bruises because he could distract himself, but knowing about the looming pain drove him crazy.
Dragging Katsuki’s arm out to be fully extended from his body, Izuku carefully lined up his shoulder.
“I’m going to pull a little and then push hard. Does that sound okay?” His voice was assuring, relaxing Katsuki who nodded through a deep breath. Though Izuku was nervous actually seeing the patient, when he focused on just providing care he seemed so calm. The boy was entirely in his element. Maybe it was the same as fighting for Katsuki, he could just let go and allow his expertise to take over.
“Alright. Three,” Izuku began with a calm breath, “two,”
“Fuck, just do it,” Katsuki growled. At the same time, Izuku said ‘one’ while striking Katsuki’s shoulder straight back in.
“FUCKING HELL,” Katsuki shouted loud enough to stop practically any other chatter in the entire nurse’s office.
“All done,” Izuku smiled, brushing off Katsuki’s minor freak out, “Are you okay?”
Katsuki took a few more labored breaths before responding, “I guess.” The ‘popping back in’ as Izuku dubbed it, was more like violently shoving it in. The pain had been white, hot, and intense, but it was only for a split second. Now, Katsuki could simply feel the twinges radiating out and leaving his body.
“You did great!” Izuku cheered, despite the office still seeming scared to get back to whatever they were doing before Katsuki’s scream. Izuku leaned low and whispered right next to Katsuki’s ear, “Don’t worry, everyone here was crying way more than you before Recovery Girl put them to sleep.”
“Babies,” Katsuki shot back, making Izuku laugh straight into his ear.
“I’m going to get you some ice. You can hang out here for a little until you feel alright to go back to the dorms,” With that, Izuku took off for a minute, once again leaving Katsuki dumbstruck in the nurse's office bed. Of course the only student aid had to be literally gorgeous and incredibly charming. Why couldn’t he just be some stupid nerd? Katsuki didn’t know how much more of this he could take.
The curtain rustled as Izuku returned with ice as promised, along with a caddy full of different medical trinkets. He placed the ice over Katsuki’s shoulder, cooling the nerves down from any lingering pain. Afterwards, he didn’t leave like Katsuki had assumed, but instead pulled up a rolling stool next to Katsuki.
“Usually we don’t treat small cuts and other basic injuries from training, but since you’re already here I thought I could clean you up a bit.” Katsuki was prone to tough out anything he believed he could handle on his own, but if he said he was fine now that meant Izuku would leave, and he would be just like every other student dreaming about the hot student aid.
“For real?”
“Of course. Besides, I already know all the third years here. I might as well get to know someone new.”
