Soft Explosions

Summary:

Kirishima is hurt during hero training which makes Bakugo show a different side of himself. Will the red-haired make this part of him come out again?

Notes:

Uh, so, I have no idea where this is going, I just needed to write some kiribaku fluff. I hope you'll enjoy it! Irregular updates!

!!Reposted to make some changes in the tags, did nothing to the content of the chapter!!

Chapter Text

“Who did this to you?” Bakugo barked at Kirishima at the sight of his fully bruised right arm. The skin had turned slightly purple. The red haired waved his hand dismissively as if it wasn’t a great deal and smiled even if the pain that was coming from his limb was strong enough to make his eyes teary.

“It’s nothing, really-”

“Dumb idiot, I fucking asked you who the fuck did this to you! Or have you taken a blow to your head too?” Bakugo went on, frowning even more than Kirishima thought it was possible.

Kirishima had been brought to the Recovery Girl after he had got a nasty hit during the hero training. He had been partly unconscious as some of his classmates had carried him all the way here and now he was laying on the bed, waiting for the sedatives to take his pain away. His right arm didn’t look well at all so he could understand his friend’s concern, but it had been just training, right? Bakugo shouldn’t lose his mind over something like this.

“Does it really matter, dude?”

The vein on Bakugo’s temple looked as if it was about to explode. The blonde was so damn angry. All Might had split the classroom in two, so a group was supervised by Aizawa and the other by the No. 1 Hero. Therefore, Bakugo hadn’t been there when his friend received the powerful blow, Kaminari was the one who told him.

“The sedatives are fucking your brains or what? Your arm turned to fucking purple, I’m surprised it’s still attached to your body. So I am asking you for the last time- Who. The Fuck. Did. This?!”

Kirishima didn’t want to test Bakugo’s limits at that moment, so he opened his mouth to reply. His answer didn’t come as the door was opened hesitantly by no other than Midoriya.
“Hey, Kirishima...” He said as he closed the distance between himself and the bed and flinched at the hearing of Bakugo’s annoyed growl.

“Hey, dude, you should totally come later.” The red haired said smiling nervously.

“You’ve heard him, loser, get lost or I’ll make sure you will sit in this bed next.” Bakugo spoke and rolled his eyes at the sight of Deku. Fucking idiot, entering and disturbing them just like that.

Deku took a step back a little taken aback. “Sorry, I’ll leave, I promise, I just wanted to apologi-”

“No, you don’t, go away!” Kirishima stopped him and grunted in pain as he unconsciously wanted to gesture using his right arm for Deku to leave. Bakugo came closer to Kirishima and pushed him back on the pillows, trying not to use too much force. “Shitty brains, don’t make this worse for yourself.” He said and then his gaze landed on Deku. “Apologize for what? Wait a minute...You...”

Damn. This has been exactly what Kirishima was trying to avoid. All that Bakugo needed was a reason to fight Deku.

“Kacchan, I’m feeling miserable, that’s why I came to apologize, I didn’t want to hurt Kirishima like this, you know that, right?” Deku murmured realizing the trouble he had brought on himself.

“Fucking nerd!” Bakugo yelled as he punched Midoriya right into the wall.

“Bakugo, don’t!” Kirishima shouted even though he knew it was futile. Once Bakugo was losing his composure, nothing could stop him.

“I’ll fucking kill him!” He roared as small explosions started lighting up in his palm. He was about to blow up Midoriya and the whole wall behind him when Recovery Girl entered.

“What is happening here?” She asked at the sight of the nose bleeding Deku that was getting up from the floor.

“This shitty broccoli is responsible for that!” Bakugo said pointing to Kirishima’s bruised arm.

“I swear, I just lost all the control for a second, I didn’t want to hurt him. Kirishima is my friend.” Deku added, his lower lip trembling.

“Don’t worry, Midoriya, all’s good.” Kirishima replied as the pain had lost its intensity. “My arm is going to be alright, right?” He asked looking at Recovery Girl who shook her head.

“Very close to be broken, young man. Even so, you are not allowed to use your right arm for two weeks. I’ll write a note for your teachers.” She replied looking through some papers. “And you two: fight outside, not here!” She added, realizing what her verdict would cause. Bakugo growled angrily.

“Get lost, if I have to see your dumb face for one second more, I’ll fucking murder you.” He wasn’t done, but he didn’t want to leave Kirishima’s side to go and fight that loser. Deku murmured another apology and didn’t think twice before leaving.

“That’s still good news!” Kirishima said with his usual smile and yawned as the medicine from the perfusion were making him more and more sleepily.

“Shitty hair...” Bakugo said and rolled his eyes, his brow softening a little. “Why the hell didn’t you use your hardening?”

“Oh, he did.” Recovery Girl was the one to answer. “If he hadn’t, I wouldn’t like to imagine in what state his arm would have been.”

“Whoa, I didn’t know Midoriya has such a manly quirk.” Kirishima answered amazed.

“Shitty Deku...I’m not done with him yet.” Bakugo murmured so Recovery Girl wouldn’t hear.

“You will spend the night here, young man, so I can make sure everything’s alright with your arm.”

“My arm? But the pain disappeared completely...”

“You’re drugged with sedatives, Shitty hair.” Bakugo said amused by the silly expression on his friend’s face.

“You’ll keep an eye on him while I’m away, alright?” The old lady asked and Bakugo nodded. “Don’t keep him up too much, he needs to rest.”

As she left, the blonde sat on the chair next to Kirishima’s bed.

“You totally lost it a few moments before.” Kirishima said out of the blue.

“Shitty idiot needs to learn to control his shitty quirk before he ends up doing worse. Now go to sleep.”

“Nah, watching you as you watch me with that serious expression upon your face is way better.” He replied and yawned again.

“Shut up before I make you sleep.” Bakugo said, the corner of his mouth slightly lifting up.

“What I mean is… you were about to murder Deku for hurting me. That’s manly, dude. Worrying about your friends is very, very manly.”

“Keh, whatever. Make sure to get revenge for what he did next time you fight him. I’d like to see that.”

“Mhmm...” Kirishima mumbled as his eyes closed slowly. “Sorry dude, I’d like to chat more, but I just can’t control my eyelids...not very manly of me.”

“That’s the whole point, Shitty hair.” Bakugo said as he watched his peaceful expression and for a moment he felt really calm. He thought that even if Deku stormed in, he wouldn’t want to blow him up.

“Yeah, but we...we never get to talk like this, just the two of us...” Kirishima murmured half asleep already.

Bakugo gulped a little taken aback. “Pff, hair for brains, I will be here when you wake up too.”

“That’s why I love you, dude.” And then Kirishima started snoring soundly as a surprised Bakugo was watching him.

“Cheesy shitty hair...” Bakugo replied and crossed his arms. Kirishima was saying all that silly stuff because of the perfusion anyway.
