The students and teachers alike at UA High can't help but notice the strange behavior of the typically stern and stoic teacher of Class 1-A. They come up with all sorts of theories but soon discover the even more surprising truth: Aizawa-sensei is simply falling in love. Fluffy Aizawa x fem!reader drabble. SFW. 2,828 words.
The way everyone looks at him when he walks in, you’d think he’d grown a second head or something.
Aizawa glances up from his phone after reading a sweet little text from you, greeting him good morning and wishing him a good day at work, only to find every student's wide-eyed, unblinking attention focused solely on him.
One second, they were all happily chattering, and then, the next…
"Hmm? What?" He asks his class offhandedly, throwing his things on the table and taking his usual seat.
But instead of answering him, the whole room erupts into a whispered frenzy.
"Did you see that? Did he just...?"
"No way! Must have been a trick of the light or something."
"What the heck? I feel so unnerved. Llike we just spotted a UFO or there’s been a glitch in the matrix."
“You guys saw it too, right? Are we all just collectively hallucinating?”
"Oi!" He calls their attention. "Would anyone care to tell me what it is exactly that's gotten all of you so worked up this morning?"
Stunned silence falls over Class 1-A again, and Aizawa can’t help but cross his arms and sigh. “Iida? Yaoyorozu? What’s going on?”
He doesn’t miss the way the class president and vice-president exchange a hesitant look before Iida answers him.
“Apologies, sensei!” He hastily gets up to bow. “I will personally make sure everyone quiets down.” He zooms around the room and gestures frantically at his noisy classmates to settle down.
Bemused by their commotion, Aizawa observes them all carefully. What could’ve caused such a stir? He wonders. And why are they all so reluctant to tell him? Did he have a piece of spinach in his teeth or something? A quick glance downwards tells him he didn’t forget to wear pants or shoes or anything, so what was it?
“If I may, sensei?” Yaoyorozu raises her hand and he nods at her. “I think everyone was just a little distracted by your change in demeanor today."
He furrows his eyebrows at the young girl. "What change?"
"Well, we’ve never seen you smile before. Or at least, not like that.”
He blinks in surprise. He’d been smiling when he walked into class this morning? "What about it?"
"Well, sir," Iida adds, taking his seat once everyone's finally settled down. "It's quite an uncommon sight. Naturally, they were taken aback."
“You usually only smile when you’re giving us a tough time in exams or training exercises, sensei.”
The corners of Aizawa’s mouth twitch upwards at that, which he quickly covers up with a small cough. “Well, enough of that. Let’s get on with today’s lesson, shall we?”
Everyone straightens up to listen as their homeroom teacher goes over a few important announcements. And although he isn’t smiling anymore, Class 1-A doesn't miss the way his usually sharp gaze has grown soft and almost...fond as he speaks to them.
As soon as the homeroom bell rings, Aizawa dismisses them with an absent-minded wave of his hand and takes out his phone to text you: Do I really never smile?
You smile when you’re rounding up bad guys sometimes. You reply almost right away. Or when you see a cat.
He chuckles. Apparently I also do it when I’m torturing my students. Then…Or when I’m texting you.
You send back a little cat emoji, and the grin you get after reading that doesn't leave your face for the rest of the day.

“Shouta! Helloooo? I said Earth to Shouta?” Kayama waves her hand in Aizawa’s face.
It seems to snap him out of whatever trance he’s in. “Sorry, what?” He blinks up at her.
She gives Yamada a look. “What’s with him today?”
“Dunno,” he shrugs, then turns to his friend. “Hey buddy, didn’t get any sleep again last night or something?”
You could say that, Aizawa thinks to himself with a smirk, then hastily scolds his features into their usually stoic expression. “No. Why?”
Kayama raises an eyebrow at him. “You've just been acting a little...off. Distracted, maybe?”
"Nothing to worry about," Aizawa reassures them, dismissing their concerns with a wave of his hand. He goes back to observing his students closely in the hopes of them moving past the subject, but Kayama and Yamada aren’t convinced. Anyone looking at him could tell something was different today.
“Sensei?” Kirishima hesitantly calls out to him. “I’m having a little trouble with my balance. Could you show me that move again?”
Aizawa nods, and everyone’s jaw just about drops to the floor when he demonstrates the proper stance with uncharacteristic patience.
"Remember to be mindful of where you shift your weight," He guides Kirishima through the motions with a supportive tone, a stark departure from his normally gruff and no-nonsense approach. "And keep your focus. You'll get it."
Kirishima does as he’s told and looks to his teacher for feedback.
"No, adjust your stance a bit like this. Yes, that's it. Great improvement," Aizawa says, offering a rare compliment.
Flabbergasted, the red-haired boy manages a stuttering, "Th-Thank you, sensei," before Aizawa moves on to help the next student.
Observing everything from afar, Kayama leans over to Yamada and whispers, “He didn’t get a concussion on that last mission, did he? I've never seen him like this."
“Check what was in his coffee a while ago. And if he still has more — oof, it was just a joke!”

“Okay, enough is enough!” Mina bursts into the room, dramatically crying. “I have to know!”
“Know what?” Kirishima asks as the others start to gather around her.
“What’s going on with Aizawa sensei? I saw him on the way here — he’s wearing a buttoned up shirt.”
There’s a collective gasp.
“Are you sure?” Momo asks.
Mina nods frantically. “And it was freshly pressed, too!”
Another round of gasps.
“And his hair was tied up!” The pink girl all but weeps, throwing herself onto the nearest desk.
“What do you think is going on with him?” Deku rubs his chin thoughtfully.
“He’s been acting so weird lately!” Uraraka whines.
As if on cue, Aizawa walks in. “Good morning, class,” he greets them without his usual gruffness.
Everyone hurries back to their seats, but Mina leans over to grab Kaminari’s sleeve, screaming under her breath, “He said good morning!”
“Look at his eyes!” He points frantically. “No puffy, dark circles or redness at all! He actually looks well-rested for once!”
“That’s where I draw the line!” Kirishima almost slams his fist on his desk. “We have to get to the bottom of this.”
Sero joins them, “Do you think Mic sensei and Midnight sensei know anything?”
Kaminari shrugs, “It’s worth asking.”
“Maybe Aizawa sensei has a secret twin and he’s pulling a prank on us?” Deku contemplates.
Uraraka shakes her head, “Sensei? Pulling a prank? I doubt it. What if there’s a new teacher at UA with a shape-shifting quirk?”
“Or Shinsou brainwashed him into being in a good mood?” Jirou chimes in.
As they huddle and murmur, Todoroki and Tokoyami shoot them curious glances, and Iida has to shush them discreetly.
They snap back to attention every time Aizawa faces them, pretending to listen to the lesson. But as soon as their sensei turns away again, the room buzzes with whispered speculation.
And though he acts none the wiser, seemingly engrossed in the topic they're supposed to be discussing, Aizawa can't help his amusement listening to their outlandish theories. A small, smug part of him relishes stoking the fires of their confusion.
He knew he'd have some explaining to do, but for now, he’s more than happy to just let them wonder.

“Oh, look who finally decided to show up!” is the first thing Mic says when he spots him. The colorful cocktail in his hand is practically empty, but he happily sips the fun loopy straw for whatever dredges he can anyway.
“Are you going to make me regret it?” Aizawa grumbles, taking his seat next to his friends.
But Mic and Midnight just snicker, unfazed. They’ve had years to get used to his grumpiness after all (and a few drinks to put them in a better mood).
"We have to admit, Aizawa," Midnight smirks up at him. "We had an ulterior motive for asking you to come hang out tonight."
"Don't you always?" He deadpans, lazily chewing at the gyoza they ordered without him. Although he doesn’t show it, he’s pleased to see there’s already a whiskey neat waiting on the table for him.
Midnight rolls her eyes as she slides it over to him, "Yeah, but aside from just getting you to lighten up as usual."
"And getting you to sing karaoke with us, which I still can't believe—"
"You promised me we'd never talk about it again,” Aizawa groans as he rubs his hand over his face. “And that you'd never let me get that drunk again.”
"Awww, come on, buddy," Yamada slings his arm around him. "What's the point of having a good story you can't tell?"
"Fine, but I'll deny it, so no one will believe you anyway."
"I don’t know,” Midnight sing-songs, swirling her margarita in its glass. “With the way you’ve been acting lately, they just might.”
He frowns at her. “Meaning?”
Mic grins, leaning forward with an impish glint in his eye, "Meaning we heard you've been keeping secrets from us, Aizawa."
"I don't know what you're talking about."
"Oh really? Then would you care to tell us why you’ve been smiling so much lately?”
“Or who you’ve been trying to look nice for?”
Realizing they weren’t going to let this go easily, Aizawa sighs and takes a deep sip of his whiskey, the familiar warmth sliding down his throat. He's not one to discuss his personal life openly, even with his close friends, but there's something about their teasing that doesn't quite irk him tonight.
Aizawa tilts his head slightly, thoughtfully. "I'm just...happy, I suppose."
“But it’s more than that, isn’t it?”
“Come on, buddy, you can tell us!” Mic nudges him playfully.
“We want to know what’s got our favorite grump acting like a—" Midnight’s hands quickly fly up to cover her gasp.
“Like a what?” Mic gives her a puzzled look, but Aizawa’s shoulders tense up at the glint in her eyes. That look usually meant very bad things for him.
“Like a lovesick puppy!” She grabs Mic’s arm, excitedly slapping it before shaking Aizawa’s shoulders and squealing into his ear. “That’s it, isn’t it? You’re in love!”
Aizawa chokes on his drink, and Mic pats him on the back to ease his coughing fit.
"Real smooth, Kayama,” he teases her.
"Sorry, but I couldn't resist," Midnight pouts, the twinkle of amusement still shining bright in her eyes.
Aizawa wipes his mouth and sets his glass down with a sigh. “Well, if you must know…There is…someone I’ve been spending time with.”
"Someone!" His friends chorus, delighted.
Mic nudges him gently. “Well? Don’t leave us in suspense!”
"Who is it? Do we know them?" Midnight leans forward, giggling.
Aizawa looks down at his glass for a moment, contemplating how much he should reveal. Although he feels a little overwhelmed by their excitement and their scrutiny, he also secretly relishes the joy of sharing this part of his life with his closest friends.
It feels good, he thinks, to be around them and to know that they care so much about him. And though he’s never been one to discuss his personal affairs, he trusts these two enough to share the parts of himself he usually kept guarded.
Seeing the expectant looks on their faces, eagerly awaiting his answer, Aizawa's ears turn the faintest shade of red.
“Do you want to meet her?”

"Had a fun night?" You greet your boyfriend with a hug when he shows up at your door well past a reasonable hour.
You don't miss the small smile on his face when he takes off his shoes. "Actually, I did. But Yamada and Kayama were pretty insistent on meeting you."
"You told them about me?" you respond, feeling a mix of excitement and nerves.
He nods, not quite meeting your gaze. "I think they'd like you."
"Really?" You plop down on the couch with him and stretch your legs atop his lap.
"Yeah," He gently grazes your thigh. "They were wondering why I've been acting so differently lately."
"Like what?"
"Apparently I'm smiling more and acting nicer and" — He air quotes — “Stopped looking homeless."
You laugh. "And what did you say?"
He shrugs, “That I guess my girlfriend just makes me really happy.”
“Awww,” you pat his cheek playfully. “What’s next? You gonna tell me you’re in love with me or something?”
"Yes? I thought it was obvious?"
"What?" Your heart skips a beat at his nonchalant admission.
“Hmm?” He looks over, and seeing the evident surprise on your face makes Aizawa chuckle. "I thought I'd been making it pretty clear, but I suppose I should say it outright. Yes, I'm in love with you."
Your heart flutters at his words, a warmth spreading through you. "Well, for someone who's known for being so straightforward, you sure took your time saying that."
He brushes a strand of hair from your face and leaves a soft, lingering kiss on your temple. “I’ll say it as many times as you want to hear it, baby.”
You lean in closer, your lips almost touching his. “Alright,” you look up at him with a sleepy smile and half-lidded eyes. “I’m waiting.”
"I love you," he whispers, his voice low and tender. He places a gentle kiss on your nose. “I love you,” and then another on your cheeks…“I love you.” Before gently brushing his lips against yours, cupping your jaw so you can’t help but gaze deeply into his dark, smoky eyes before he finally closes the distance between you.
“Mhhm.” You smile, contentment washing over you like a gentle wave. "I love you, too, baby."
