Anon: How about headcanons for Deku, Bakugou and Kirishima meeting their future (female) S/O for the first time and freaking out because it's kinda love at first sight??

Your wish is my command~

Izuku:

-This boy is just trying to be the best damn hero he can be 

-He didn't expect any of this when he first steps through his classes door on a normal Wednesday

-There in his seat is a girl, smiling at Uraraka as the latter excitedly chatters away.

-Izuku just stops for a minute frozen, this girl is beautiful!

-Her hair just shines and her smile is radiant, he's blown away from the first glance and a goner when his eyes meet hers

-Pshoooo goes his heart

-He's blushing at the colour of her eyes and the way they stand out

-He eventually has to stop staring when she cocks an eyebrow at him and tilts her head in such a cute way

-He's a little mortified that one of the first things he says to her is that she's sitting in his seat, but the way the colour drains from her face and then comes back red tinted makes everything in his life feel worth it

-He feels a little happy that she sat where he is now and he is so excited to get to know her as a classmate and potentially more.

Bakugou:

-First of all he is soo pissed off!

-What the fuck is this random girl who thinks she can just sit in his seat? 

-He slams a hand flat on her desks which catches her attention, she turns from talking with Momo

-His heart stops and he forgets how to breathe

-His eyes narrow at her as they dart across her features

-Her lips are slightly parted, eyes a little wide from the surprise of the loud noise

He lets out a really quiet "shiiiiiiit"

-Why the fuck did she have to be cute?! What the fuuuuck

-OK Bakugou be nice say something witty to charm her

-"Get the fuck out of my seat you skank"

-No! Dickcheese! His face drains of colour

-"OK, jizzwizard" She giggles as she stands and moves to another seat 

-He is pleasantly surprised to say the least and takes his seat, feeling like his bones are thrumming

Kirishima:

-Oooo a new student, is it a boy or a girl?

-What do they look like?

-Are they manly?

-She comes in and bloody hell, bury him with the bunch of other male students that lose their shit at her entrance

-In other words, bury him with the other hopelessly in love boys. 

-She comes in with a shy smile and a slight blush, makes her introductions in an adorable voice and sits down quite quickly.

-Hoo boy, he's down with the sickness, she sat down right in front of him and it's so close he can smell her

-She's gonna be in his class until they all graduate

-He can get to know her

-Sweeeeet
