Some headcanons on how the three big boys would react to seeing someone flirting with their s/o
My headcanons tend to me some kind of frankenstein between actual headcanons and a scenario (like a scenario in bullet point form) so these tend to get a bit lengthy!
Midoriya Izuku
he had been held up talking to all might after class, so he wasn’t able to walk with you to the cafeteria
one his way, he sees two people talking in the hallway. thinking nothing of it, he’s about to walk past, until he hears a familiar voice
“please, I already told you, I’m not interested.”
his neck almost snaps from how fast he whips his head in your direction and his heart feels to big for his chest when he sees you with your back against a wall, frowning at the second year student in front of you
midoriya swears he can feel his stomach in his throat
he knows that you’re very capable of handling yourself, and that if things became too much you very well could force yourself out of the situation, but he still felt the urge to march up and sweep you away
your eyes met his over the boy’s shoulder and your eyes widen, a small smile growing
“ah, see, here’s my boyfriend! y’know, the one I told you about.”
you basically vaulted over this guy’s shoulder and bury your green haired boyfriend in a tight hug
you look back over to the boy who had just confessed to you from your spot next to izuku, your face smushed into his shoulder and your arms snugly around his waist
the boy’s face turned red, his expression an awkward mix between embarrassed and almost ashamed
izuku, on the other hand, had wrapped his arm around your shoulders with a bright smile on his face as he nodded at you, before moving his gaze to the second year, doing his best to glare at him intimidatingly
after a moment of watching the second year flee down the hallway you two are finally on your way to the cafeteria
“[y/n], are you okay? I hope he didn’t bother you too much. I’m sorry I was gone for so long,” the afterwards is when his worry and pseudo-jealousy comes to light
his arm is around you for the rest of your break, and his hold is tighter than usual and he seems unwilling to let you go
he almost yells at kaminari when he tries to talk to you, a garbled exclamation of ‘stop bothering my s/o!’
he apologises quickly to you and kaminari, and chills entirely once you give him some attention
he’s insecure more than anything, so giving him reassurance and affection is the best way to make him feel better
Bakugou Katsuki
you’d told him you wouldn’t be too long, so why hadn’t you met up with him yet?
so he goes on a begrudging search for you, stomping around the halls loudly, grumbling out your name
he finally peaks around a corner, already annoyed, only to see you scowling at someone, your arms crossed over your chest, your eyes portraying complete disinterest
“oh, c’mon [y/n], me both know I could make you happier than bakugou. he’s too intense for you.” the boy in front of you says, and the ash blonde in question actually waits a moment, wanting to see what you said
he wasn’t insecure of COURSE NOT
he was just curious of how you would reply
to bakugou’s great pleasure, you snort, raising an eyebrow
“you wish, buddy.”
bakugou lets out a boisterous laugh, loud and cocky as usual. he comes stomping up, shoving the guy away from you and throwing his arm over your shoulder, dragging you in close to his chest
“you heard ‘em shithead, get the fuck outta here.” he almost cackles
you’re walking home with him when you finally notice that his arm is still around you, and he’s growling at every male that walks by like he’s your personal guard dog
you know that he might get even angrier if you bring up his jealousy so you settle on snuggling up to his side
usually he would get annoyed with too much affection, but when he’s feeling territorial it just makes him feel more smug and confident in your relationship
so once you get home just lay all over him basically. he’ll be smirking to himself as he enjoys your affection, bragging in his imagination (also imagining all the different ways he could humiliate whoever had been flirting with you in the coming days)
basically, if you point out that he’s being jealous, he’ll draw further away from you, so just give him silent attention
Todoroki Shouto
he looks over during a break to see kaminari standing next to your desk, a flirtatious grin on his face
todoroki likes to consider himself a level headed person, but we all know that he isn’t the most in touch with his feelings
he kind of watches awkwardly from his seat, glare getting more intense with each second
a few of the other students can basically feel the freezing cold aura coming from him
you look over to him as you feel the drop in temperature, a questioning look on your face
shouto looks away, unsure why he’s acting this way
so you go up to him, kneeling next to his desk, resting your chin on his desk as you look up at him curiously
a red blush ignites over his face at your expression and cute position
“is everything alright, shouto?”
K.O!!!!!! you know his weaknesses too well
he basically melts into his seat, smiling ever so softly at you
his finger gently touches your cheek and he nods slightly
“everything’s fine. i was just feeling a bit weird. sorry if i bothered you.”
always so mindful of everyone else’s feelings while not assessing his own
you had figured out that he was feeling jealous, and you wanted to help him identify his feeling’s better, so you urge him to explain further
finally, you help him get to the realisation that he was actually jealous. of course, he apologises, thinking that jealousy is an ugly and undesirable emotion
so you’ve got to basically walk him through how to emote properly, and also let him know that he’s V A L I D
