Katsuki Bakugo wasn't one to be held back by anything. He was relentless, unstoppable a force of nature with a personality as explosive as his quirk. But even he wasn't immune to human ailments, a fact he would learn the hard way.

It started as a small itch. Barely noticeable at first, but it was there a faint tingle on his arm. Katsuki had shrugged it off, figuring it was just a bug bite. But by the time he'd gotten out of bed the next morning, the itch had spread, and he could feel several more spots tingling across his body. He looked down, spotting tiny red bumps forming on his arms and chest.

"Great, just what I need," he grumbled to himself. "Stupid rash."

Katsuki didn't think much of it. He was Bakugo, for crying out loud nothing could stop him, especially not some dumb rash. He quickly dressed in his school uniform, ignoring the persistent itchiness, and headed out the door to U.A. High School. He was determined to push through whatever minor annoyance his body was throwing at him. Missing class was not an option; he had training, and he needed to prove he was the best.

The day started off normally enough. Katsuki was his usual intense self, barking orders at the other students during their group exercises and glaring daggers at anyone who dared to question him. But something was off. Eijiro Kirishima, his boyfriend, was the first to notice.

Kirishima had always had a keen eye for Katsuki's moods. He knew when Katsuki was in a good mood (rare), when he was annoyed (common), and when something was really bothering him. Today, there was something different about Katsuki, something he couldn't quite put his finger on.

"Hey, Bakugo!" Kirishima called out during their lunch break, catching up to him as they headed toward the cafeteria. "You alright, man? You seem... I dunno, off today."

Katsuki shot him a glare, but it lacked its usual fire. "I'm fine, Shitty Hair. Quit worrying about me."

Kirishima frowned. That was another red flag Bakugo's insults were usually sharper, more biting. This one had been half-hearted, almost as if he didn't have the energy to put real venom into it.

"You're not fine," Kirishima insisted, grabbing Katsuki's arm to stop him. His hand brushed against one of the bumps, causing Katsuki to wince.

"What the hell, Kirishima?!" Katsuki snapped, yanking his arm back. But his reaction was slower than usual, almost sluggish.

Kirishima's eyes narrowed as he noticed the red spots dotting Katsuki's skin. "Dude, are those... chickenpox?"

Katsuki stared at him like he'd grown an extra head. "What? No way. That's kid stuff!"

"Yeah, well, you can still get it if you haven't had it before," Kirishima replied, his voice filled with concern. "Come on, you gotta see Recovery Girl. This could be serious."

"I'm not going to see Recovery Girl for some stupid rash!" Katsuki snapped, though even he could hear how weak his argument sounded. The truth was, he was starting to feel worse his head was pounding, and he was starting to feel dizzy. But admitting that would be like admitting defeat.

Kirishima wasn't having any of it. "Bakugo, this isn't just about you being tough. If you've got chickenpox, you could spread it to everyone else! You need to take care of yourself, man."

Katsuki opened his mouth to argue, but a wave of nausea hit him hard. He swayed on his feet, and suddenly, the world spun around him. Before he could collapse, Kirishima was there, catching him with strong, steady arms.

"Bakugo!" Kirishima's voice was full of panic now. "I'm taking you to Recovery Girl. No arguments."

Too exhausted to protest, Katsuki let Kirishima half-carry him to the nurse's office. By the time they got there, he was shivering, his skin burning with fever.

Recovery Girl took one look at Katsuki and immediately ushered him onto a bed. "This boy's got a serious case of chickenpox," she declared after a quick examination. "He should have been home resting, not running around here."

Kirishima winced at the reprimand, feeling guilty that he hadn't noticed sooner. But Katsuki, even in his feverish state, managed to grumble, "Told you... I'm fine."

"Yeah, sure you are," Kirishima muttered, pulling up a chair beside the bed. "You're just going to rest here for a bit, okay?"

Katsuki tried to glare at him, but his eyelids were heavy, and his body was betraying him. "I don't need... rest," he mumbled, but the sentence trailed off as he drifted into a fitful sleep.

Kirishima stayed by his side, watching over him. He knew how much Katsuki hated feeling weak, hated showing any sign of vulnerability. But this wasn't about toughness; it was about health. As stubborn as Katsuki was, he needed to understand that even the strongest heroes needed to take care of themselves.

Hours passed, and Katsuki woke up periodically, each time a little more aware of his surroundings but still too weak to do much more than mutter a few words. Recovery Girl administered medicine to help with the fever and the itching, but she insisted that Katsuki needed bed rest—preferably at home.

"Kirishima," she said kindly but firmly, "take him home. He'll recover faster in a comfortable environment. And make sure he stays there until the pox clears up."

Kirishima nodded, helping Katsuki to his feet. The fever had taken a lot out of him, leaving him unsteady, but Kirishima was there to support him. Katsuki leaned on him more than he would ever admit, his pride barely intact as Kirishima half-carried him out of the school.

Back at Katsuki's dorm room, Kirishima settled him into bed, making sure he had everything he needed—water, blankets, and medicine within arm's reach. Katsuki, too tired to fight anymore, simply lay back and closed his eyes, his usual bravado gone.

"Thanks... for taking care of me," Katsuki muttered, almost inaudible.

Kirishima smiled softly, brushing a stray hair away from Katsuki's face. "Of course, man. That's what boyfriends are for, right? Now get some rest. I'll be right here if you need anything."

Katsuki's only response was a quiet grunt, but Kirishima could tell it was his way of accepting the help. He watched over him as he drifted back to sleep, the tension finally leaving his body.

As Katsuki slept, Kirishima couldn't help but think about how even the strongest, most stubborn people needed someone to lean on sometimes. And if Katsuki Bakugo, the fiercest person he knew, could learn to accept help, maybe there was hope for all of them.
