Happy birthday boom boom boy

Happy birthday Kachan. You blond bitch I love you. This was supposed to be posted on his birthday but I do not conform to rules... I was busy, forgive me.

This is just your typical Katsuki Bakugo birthday fic, and a lil something something from Deku as payback for all those birthdays...

~~~~~~~~~~~~~~~~~~~~~~~~~~~

"Bakugoooooo" Katsuki looked up to see Ochako with a shit-eating grin above him, they were in the common room and he was just starting to enjoy a calm moment.

"Cheeks" He grumbled going back to his book. Maybe ignoring her would work. Ochako plopped herself beside him and giggled. Katsuki slowly turned to her and glared.

"You better have a good excuse to ruin my solitude right now" he scowled. The round bitch had the balls to giggle to his face.

"Oh come on, I know you love me" She grinned batting her lashes at him, he stared unamused.

"It's your birthday tomorrow, what do you want? or wanna do?" She asked Katsuki tske'd and turned back to his book.

"For you to leave me alone, I swear if I see fancy shit I'll blow this place up" he said, Ochako rolled her eyes.

"No you won't, Aizawa-sensei will have your ass expelled if you do, come on! you really don't want anything?" Ochako whined. Katsuki rolled his eyes and stood up scowling at her.

"No! I mean it! Or ask your shitty boyfriend! Leave me alone!" Ochako frowned (with a noticeable blush) but didn't follow him away.

"Welp, there goes on surprising him... or throwing him a party" Ochako huffed.

"Throwing who a party?" Ochako jumped when Deku appeared beside her with his notebook and pen in hand.

"I-isn't it Bakugo's birthday tomorrow Deku? Any ideas?" She asked, moving away slightly to give her heart a moment to calm down.

"Oh! Yeah Kachan doesn't do parties, but don't worry Uraraka, I know what he would like" He grinned, a little mischievous and devious than she's used to.

"M-mhm, what?" Deku just grinned wider.

Katsuki woke up the next day with caution, he almost didn't want to go down expecting a large surprise.

"Happy birthday Bakugo!" he blinked, everyone was at the foot of the stairs crowding the place with party poppers and Deku holding a small cake with Katsuki's hero color theme and his mask as the topper.

"I told you not to make a big deal out of this!" he tsked but walked down nonetheless.

"Oh please Kachan, you enjoy the attention," Deku grinned, pushing the cake to him with a mischievous grin.

"Make a wish Kachan" Katsuki stared at him skeptically. he shrugged and made a wish before blowing out the candles.

And it only took a split second and a giggle before his vision went black.

"splat"

Everything stopped.

"EVERYONE MOVE!" Deku was the first to bolt as soon as the cake splattered on the floor.

"Catch me if you can Kachan!" By the time Katsuki wiped the icing off his face it was just him and the small fallen cake on the floor.

"DEKU YOU DAMN NERD!" He roared and picked up the cake from the floor he bolted to the door but stopped when he saw a large water gun on one of the tables and a basket of water balloons beside it with a note.
