Work Text:
Izuku did not feel little, he was big, not a bit of little in him, he classified as a neutral. Or at least that’s what he told everybody. Not that there was anything wrong with being a little, but the stigma of being a little, and quirkless, meant the green haired boy didn’t want to touch either again. He. Wasn’t. a. little. He wasn’t feeling little. The fogginess in his head, and the overwhelming urge to seek physical attention and cuddles, and wanting someone to look after him was obviously just sleep deprivation.
There wasn’t many littles in class 1A, or in the hero business at all, some people saw them as liabilities, but if a little regressed regularly, there was no real risk to them slipping randomly at work. But deku had been putting it off, he didn’t like regressing on his own, and he couldn’t admit to anyone else he was a little! Todoroki seemed to have been catching on though, giving the younger green head subtle affections, head pats, compliments, letting him hold his uniform to ground himself. It all would have been so nice if having a caregiver’s attention hadn’t made his need to slip down grow even stronger and stronger over the last few weeks when he couldn’t let himself do that! What if his class needed him? What if there was another villain attack? What if…
Oh, that’s to complicated, all he wanted right now was huggies, and a paci and stuffie, and a blankie, why was that so hard!
UA had made it clear at the start of the year, and when they moved into the dorms that if anyone regressed without a caregiver or regressed unexpectedly, they should go to their homeroom teacher (most of whom were caregivers themselves, including aizawa). But aizawa didn’t know he was a little, though he may have been catching on as well (he had seen the sneaky glances aizawa and Todoroki shared whenever deku had accidentally let himself slip and his little self had almost sucked his thumb in lesson.
He couldn’t go to Todoroki, that’d be embarrassing, but maybe aizawa wouldn’t judge as much?
Deku could feel himself slipping more, he needed to make up his mind quickly.
Aizawa was strict in lesson but when a little or vulnerable kid was put in his care he was as caring and loving (maybe even more so) as any other caregiver. Mic often made fun of him for adopting all of class 1A.
Suddenly Izuku’s feet were moving without his consent. want cuddles! Want aizawa! I want him I want him I want him. God he was about to out himself to the entire faculty and there was nothing his quickly slipping away big brain could do about it.
He knocked on the door once, half expected and half hoping the older, gruff man wouldn’t answer, and then knocks again, this time accompanied by the sound of shuffling inside. Judgement. He lied for so long. What if he can’t be a hero. Cuddles.
Finally, the teacher opens the door, wearing his usual all black outfit with matching black eyebags, looking down at the very anxious looking boy Infront of him trying to mask his surprise.
“what do you want problem child?”
Part of him wants to let tears fall, let himself run straight into his teachers arms until this horrible overwhelming feeling goes away, the other part still fighting his little side like no tomorrow, trying to keep this oh-so-vulnerable side of him hidden away like he had for years in middle school to prevent further bullying.
“I- I” he begins to play with his fingers. “we were t-told to come to u” his voice came out younger than he had wanted, struggling on some of the words that didn’t seem to fit in his mouth quite right.
“come to me for what?” the older man had his eyebrows raised, he obviously knew Izuku’s predicament, if the damn kid would just trust the adults around him for once and know they would take good care of him. He had been showing signs of being a little since the start of the year that any other little or caregiver would have immediately picked up on, Todoroki had come to him in concern at one point at Izuku damaging himself by not letting his body give into the regression it was becoming ever so clear was needed. So aizawa had been expecting a drop, and a hard one at that. Maybe he should have tried to talk to the trembling boy outside his door before it came to this, but he’d wanted to wait till he was ready and obviously waited too long.
“I feel little, an- an- “
Oh god this kid. Tears began to treacle down his face, overwhelm clearly showing on his face.
“want cuddles. I want cuddles badly. An I dunno what to do cause I’ve never slipped this hard before and they said to come to you! But you don’t know ‘m a little an- “
It was quickly becoming a temper tantrum the longer he talked. Izuku’s upset over being little, over not being able to control his (very quickly) slipping mind, and months of holding back what he obviously needed.
Aizawa opened the door wider, pulling the smaller boy in an encasing him in a warm hug, he fought a little at first before melting into it, releasing more sobs as his teacher fumbled to shut the door behind them.
“I’m s-sorry, I’m a big boy I promise”
“you don’t need to be”
They held onto each other until the sobs stopped, finally allowing his eyes to drift shut for a while and allowing his teacher to get his bearings.
