____________________________________________________________________________

Kaminari was diligently working on his math homework in his dorm room. He actually understood the lesson in class today so he decided to get to work on it before he forgot everything. He had already completed the first side of the page and was nearly finished with the back when he heard a knock at his door.

Before he could get up from his spot on the floor to answer it, the door swung open. Bakugo came barreling into his dorm. He seemed excited about something, an odd sight to say the least.

" Hey, Kats! What's up?" Kaminari asked. He wasn't little at the moment but he had a feeling he would be very soon. The blonde at the door was very out of breath.

He took a deep breath and stood up straight. His left hand was hidden behind his back for some reason. " I got you something." He said quickly. His hand came from behind his back and displayed the Olivia Rodrigo vinyl album titled Sour.

The electric blonde gasped and jumped to his feet. " No way, you didn't!" He yelled, snatching the album from Katsuki's hands. Denki had been trying to get his hands on the vinyl for months but every time he went out to get it or tried to get it online, it was sold out.

" I did, it was the last one at the music store down the street. I went to see if they had the Mother Mother album and I saw that one. I know you've been looking for it for months so I couldn't just leave it." He replied, sitting down on the bed. Kaminari was still in shock, he hadn't even thought to get out his record player and play it.

At least not until Bakugo got up and got it out himself. " Give it here, we should listen to it." The caregiver said as he grabbed it from little sparky. All the little did was nod and bounce on his heels.

Bakugo put the vinyl on the player and it began to play the sweet sound of Kaminari's favorite songs. Instantly, the boy slipped into his headspace at the music. He began to bounce around and happily clap his hands.

" Tank you, daddy!" He shouted over the music. He finds it hard to control his volume in this state. The state of pure excitement.

All the caregiver could do was laugh and respond with " You're welcome, kid. I'm glad you like it." He ruffled the yellow hair on his little's head and kissed his forehead. Denki nuzzled his head into his hand and began bouncing again shortly after.

The little one danced and clapped his hands throughout the whole album. He replayed it over and over and over. To the point where Bakugo almost regretted the purchase.

Almost.

The look on the boy's face and the happiness in his dance was worth the pounding headache. " Daddy, daddy look! I dancin!" Denki called, excited to show Bakugo his cute little wiggle.

" I see that, bug. I love your dancing!" Bakugo made his way to sit on the bed while Kaminari continued to wiggle and clap. He got so excited his hands started to spark up and almost sparkle. Again, he clapped and clapped. At one point he went from clapping to simply flailing his hands about.

His giggle lit up the room. Quite literally, with his excitement came a recharge of the electricity in the room. Unlike Kaminari, Bakugo took notice of the sudden charge in the, now flickering, lightbulbs. " Okay okay, let's calm down for a bit, baby. I think it's time we calm down for a bit. Let's turn it off for now and we'll play with your stuffies for a bit." The caregiver said as he took the boy's hand into his own.

Kaminari pouted, he didn't want to stop listening to his music! " But daddy, I no wanna stop! I likes my music!" He whined, slightly stomping his foot.

This is not going to be pretty. Bakugo thought as he stood from the bed. He took the little's shoulders in his hands, as he made full eye contact with him. " Baby, we're getting a little bit too excited about the music. Daddy is so happy that you like your present but it's not safe for you to be getting this excited, okay?"

Denki again pouted but nodded his head in understanding. He knows he has trouble controlling his quirk when he's little, sometimes not even realizing it. " Good boy, now, how about we turn on some cartoons and play with your stuffies for a bit, hm?" Bakugo said as he placed his index finger under his baby's chin, lifting his head to look him in the eyes.

The little nodded again and sniffled. The caregiver knew it would take a moment or two to get him in a better mood but he was willing to take that extra time if it meant the boy calmed down. He knew he would have to work on controlling his quirk with him.

" Thank you, baby. I appreciate you listening to me. Would you like to pick a treat from the reward box? I think you've earned one." Like a light switch, Denki was happy again. Excited to pick a treat, he rushed over to the bin in the corner of his room and sifted through the contents to find one specific thing. He had been waiting for this treat for weeks. Usually, his daddy only gave him a treat when he has a full row of stickers on his good boy chart. It had been kind of a rough month so he wasn't expecting to get a treat so soon. That being said, he'd had his eye on a certain little Pikachu stuffie. It was only the size of his hand with big sparkling yellow eyes. He wanted it so bad, which is why Bakugo purchased it and put it in the box.

Once a month, the couple goes to the mall to refill the box. Denki is allowed a certain amount of money to choose whatever items he pleases to use as a reward. It was a good system that they had established at the beginning of their relationship. It had worked perfectly ever since.

" Dis one!" Denki called as he held the small toy in his hands. He began bouncing around yet again, getting excited all over again. The sight was adorable to his caregiver. However, as much as he loved his baby being excited, maybe it wasn't such a good idea to give him a new toy after his electric mishap just moments prior.

Just as Bakugo had predicted earlier, the little got so excited that he, unintentionally, drained all the power from the dorm building. In the darkness, groans of annoyance were heard from the common area.

Bakugo pulled out his phone and opened the dorm group chat, sending a quick apology.

' Sorry guys, that's my bad. I gave the baby a new toy.' 💛
