Chapter Text
After that episode in the kitchen, they retreated to the common room and were greeted with the rest of Class 2-A. “Hi Izuku, we brought them here to introduce themselves!” Uraraka explained beaming as she tried and somewhat succeeded to arrange the class into last name alphabetical order.
Bakugou groaned in annoyance as he plopped himself down on the sofa and sat Deku next to him. Deku was trying to hide behind him to avoid all the attention of the others. "I don't think I need to be here for this, I already know your names." He protested as he moved Deku to his lap.
"Huh, really? I wasn't sure since you never use our names," Todoroki countered sarcastically.
"Shut up scarface, I know your names I just prefer the nicknames," Bakugou responded earning an eye roll from his classmates.
"Kacchan loves giving people nicknames because he wants a nickname as well," Deku squeaked as he got comfortable on Bakugou's lap.
"Shut up Deku, why the fuck would think that?"
"Because you were so happy the first time I called you Kacchan!" Deku exclaimed as he giggled and bounced up and down from excitement."Kacchan if you keep swearing I'm going to tell auntie and uncle and they'll take all your toys away again." He said as he slowly stopped laughing.
"Yeah Kacchan, you shouldn't cuss so much or you'll get in trouble." Kaminari snickered as he hid behind Kirishima for protection; as the others laughed along.
Bakugou was about to retort but Deku beat him to it. "You can't call him that only I can call him that," Deku said as he crossed his arms and glowered at Kaminari trying yet failing at being intimidating. The others had a hard time stopping themselves from cooing at the sight of a child Deku trying to glare.
"Okay we can use different nicknames then, is that cool with you Bakubro?"
"No shitty hair, I'd rather you use my given name."
"Only if you use our given names and we know that's not gonna happen anytime soon," Uraraka stated smirking slightly. "Now back to the subject at hand, introductions," she continued ignoring Bakugou as he rolled his eyes and slumped back onto the couch in resignation.
With that done they finally started the introductions
___
Bakugou sat back and tried to zone everyone else out while he used his phone. He succeeded for the most part but he was aware of the squirming kid on his lap. Every time Deku was introduced to someone new and learned their quirks he would start bouncing and fidgeting in excitement.
After the introductions, most of the class left but a few stayed.
“Kacchan, What’s your quirk?” Deku asked excitedly bringing Bakugou’s attention back to him.
“Explosions,” Bakugou said as he showed him a few.
“Woah, cool, I knew your quirk was going to be the coolest!” Midoriya exclaimed in awe as he grabbed Bakugou’s hand and examined it while he rambled on. Bakugou didn’t even have to stop him this time because this time he stopped himself. “But wait, What’s my quirk?” Midoriya said as he looked at Bakugou expectantly.
Uh, shit. Bakugou sat there for a moment looking wide-eyed at Midoriya, unsure of what to say. Fortunately, he didn’t have to say anything because Uraraka said it for him, “You have a cool quirk too Izuku-kun,” she said as she punched the air in imitation of Deku punching the robot. “It makes you really strong and fast too,” she continued.
Deku stared at her in amazement and joy, then he looked at Bakugou for confirmation. When he nodded in agreement Deku started bouncing in excitement and mumbling about his quirk. Bakugou sighed in relief as he slowly relaxed again. A moment later, Deku’s mumbles turned into a yawn.
So Bakugou got up grabbed Deku and made his way to the elevator heading for his room.
In front of his door was a few boxes stacked together with a key for Deku’s room on them. Bakugou grabbed the key and put it in his pocket. He then set Deku down and hefted the boxes up easily and walked back into the elevator with Deku following him.
“Where we going?”
“To your room,” Bakugou answered as they walked out the elevator and made their way to Deku’s door.
He put the boxes back down and grabbed the keys from his pocket, he then used the key to open the door and walked into the room. The room looked exactly the way he last saw it cheesy and filled with All Might merch.
“Woah, so cool!” Deku said as he bounced around in elation eyeing all the posters and action figures with excitement.
Bakugou rolled his eyes and muttered, “Of course you think it’s cool,” as he set the boxes back down inside the room. Midoriya didn’t notice it or chose to ignore it as he awed over the future or older him room. Bakugou worked around him and looked through the boxes to find the stuff he asked for. One of the two boxes contained only food, while the other was clothes and shoes.
“Izu, come here,” Bakugou called after picking an outfit from the box, “You don’t have to wear that anymore,” Bakugou said indicating to the baggy T-shirt Deku was wearing. Deku nodded excitedly after seeing the outfit was an All Might themed outfit. He quickly removed the shirt and barely stopped himself from vibrating in excitement while Bakugou watched fondly, even though if he asked he’d deny it.
After Bakugou put on the clothes and finished tying the shoelaces, Deku quickly put on the hood- the hood was a version of All Mights hair antennae -and punched the air while yelling, “I am here.” He grinned up at Bakugou and seemed to remember something.
“Kacchan whats my hero name? What’s your hero name? Did we become the Wonder Duo? How-” Midoriya started asking question after question.
“One at a time nerd,” Bakugou cut him off not fondly mind you. “Okay, my hero name is Ground Zero yours is Deku, and No we did not.” As Bakugou answered his questions Deku’s face fell and filled with tears.
“W-Why would I pick De-Deku,” Midoriya cried out forlornly and confused.
“Um, because you changed the meaning of the name from useless into ‘You can do it’ plus fucking Pink cheeks convinced you,” Bakugou said flustered as he tried to comfort Deku.
“But I don’t like it!” Midoriya pouted.
“You’ll like it in the future.”
“No, I won’t.”
“Yes- you know what I’m not getting in a fight with a 4-year-old,” Bakugou grunted as he got up off the floor.
“Hmph, and wait, what do you mean we didn’t become the Wonder Duo?” He said brows furrowed and head tilted in confusion.
“I mean we didn’t become the Wonder Duo,” Bakugou snarked as he sat on the bed and Midoriya followed to stand between his legs.
“But why?” Deku whined petulantly.
“Because we’re rivals, haven’t we already had a conversation like this.”
“Yes we have, and as I said last time I don’t wanna be your rival.” As Deku said this Bakugou elected to just not say anything to that. Bakugou’s silence must have sounded like a confirmation to him because he continued. “So, when I grow up we going to become best friends, become the Wonder Duo, then get married!”
“Oh for fucks sakes we back to marriage,” Bakugou muttered quietly to make sure he wasn’t heard.
They were interrupted by a knock on the door and Todoroki peeked in and said, “Time for dinner,” leaving just as quickly as he came.
Bakugou quickly followed aware of how quickly food was gone while Deku waddling behind
___(After Dinner)
As Bakugou reclined back in his bed- ready to finally go to sleep after a long day -he was interrupted by a knock on his door. The door opened and Deku peeked inside, “Kacchan, are you awake?” he said hesitantly walking inside.
Bakugou grunted a confirmation, so Midoriya walked in closed the door and headed for his bed. He climbed in with little difficulty then got under the comforter and nuzzled up to Bakugou. During that Bakugou just stayed still and watched, “Why?”
“I don’t wanna sleep by myself,” Midoriya whispered muffled in Bakugou’s neck. Bakugou accepted it and kept quiet. Midoriya broke the silence by saying, “Kacchan? I love you, Mama always says I’m too young to know what love is but, I know I love and wanna be with you forever…” Deku murmured yawning and trailing off at the end. His eyes fluttered closed and he fell asleep.
Bakugou’s breath hitched because of how adorable that was. He closed his eyes and tried to stop himself from cooing, “Fuck, this kid is going to be the death of me,” He said as he snapped his eyes open and tried to suppress the smile creeping onto his face.
So, ok maybe this won’t be as bad as he thought...
