Bakugo stared down at the infant with a displeased grimace on his face, his hands held up and ready to take action but hesitating to do so. Many of his classmates, all of them male, hovered around his shoulders, the lot of them peering down in morbid curiosity but unwilling to jump in and assist with the task at hand. Meanwhile, Kansuke started up at the lot of them with wide expectant eyes, as though wondering what was taking the teens so long.

"C-c'mon, man! Just get it over with, would ya?" Kaminari egged on from somewhere over the explosive teen's shoulder, though he was conspicuously keeping his distance.

"Shut your mouth of you're getting this shit thrown in your face when I'm done!" Bakugo snapped back in reply, though that promise didn't make it any easier to bite the bullet and get the job over with.

"Jeez, how many third-years does it take to change one diaper? Some big tough heroes you're gonna be…" Jirou mumbled boredly, twirling one of her earphone jacks idly around her finger as she watched from the next couch over.

"Y-yeah, well it'd be going a lot faster if one of you would help!" Mineta shot back from where he was cowering behind Ojiro's tail. Yaoyorozu, who was sitting next to Jirou to observe the farce, shook her head firmly.

"No way. You're not pawning this off on us just because none of you paid attention when Melissa showed you how to do it before. It happened on your watch, so you get to clean up the mess."

Once it looked like they wouldn't be getting any help from the girls, the gathering of boys returned their attention to the infant once more, each staring down at the child as though he were a ticking time bomb. Bakugo let a frustrated growl rumble in his throat before turning his wild glare towards one of his classmates in particular.

"Hey, Half n' Half! You've got brothers and sisters, right? You know how to do this?"

Todoroki couldn't help but blink in mild confusion at the question.

"I was the youngest, though. I've never done this before."

"You guys really should learn stuff like this while you have the chance," Uraraka commented from where she leaned over the back of the girls' couch. "What are you gonna do when you become fathers yourselves?"

"Not that I trust half of these losers with kids of their own…" Jirou snarked under her breath, though it didn't go unnoticed.

"Hey, you wanna say that to my face?!" Bakugo roared out, though he was cut off from making any real threats when an unhappy whine pulled his attention back. It seemed Kansuke's patience with the lot of them had finally run out, and within seconds the infant was wailing in protest.

"Oh no…" Melissa sighed out in exasperation. "You guys better hurry if you're gonna do it. I don't think Dad would be too happy with us if we bring Kan back with diaper rash…"

The threat of annoying All Might seemed to motivate the group of teens more than anything else could – one of them in particular more than the others, in fact. Midoriya suddenly broke away from the group, dashing over towards the couch the girls had gathered around and stopping in front of Yaoyorozu. The class' vice president merely narrowed her eyes slightly.

"I already told you we're not going to do it for you, no matter how much he cries. This is your responsibility."

"I-I know, I just… Can you make something for me, at least?"

Momo was willing to assist that much, at least. Soon enough, Midoriya made his way back to Kansuke with a clothes pin clamped on his nose and an expression of determination on his face.

"A-all right, here goes nothing!" he called out before diving into action. He remembered what he'd been shown earlier, as well as when he'd asked All Might himself to show him how during one of his visits, but it was distinctly different now that he was the one that had to do it – especially since Kansuke was currently bawling his eyes out. Even so, he tried his best to wrangle the squirming infant and get the whole ordeal over with as soon as he could. Finally, after what felt to the teen like ages but was surely only a minute or two, Midoriya tossed the old diaper in the trash with a relieved sigh. His classmates behind him erupted into applause, most just glad they didn't have to do it themselves. The young hero couldn't help but puff out his chest triumphantly, not used to getting that kind of praise. Jirou, however, merely rolled her eyes.

"Jeez, you guys act like he just saved the city or something. It was just a dirty diaper, not a damned terrorist plot…"

Even as Midoriya's shoulders wilted slightly at that comment, Melissa's amused giggle could be heard in response.

"Oh, I dunno, Kyoka. I think he deserves some praise for his first time."

At that, Izuku could feel his cheeks heat up in an instant, and he ducked down to finish re-dressing Kansuke in his onesie, the infant thankfully much calmer than he was a moment ago.

"W-well… I-it wasn't so bad…" he attempted to boast bashfully, though whatever composure he could muster seemed to dissolve into nothingness in front of Melissa. He tried to distract himself by tending to his mentor's son, lifting the baby up to lay against his shoulder, his spare hand rubbing lightly at the tiny redhead's back in an effort to soothe away the last of his tears. Kansuke calmed down soon enough, but it seemed a new need had gripped him, at least if the way he gummed hungrily at Midoriya's shirt was any evidence. His cheeks heated further, though for very different reasons this time.

"U-uhhh, I-I think he's hungry," Izuku stammered out helplessly, finally turning towards Melissa once more as though begging for help. He could hear Bakugo letting out a scoff from somewhere behind him.

"Again?! Didn't we just feed him a little while ago?" the explosive young hero growled out in annoyance.

"That's kinda what babies do. It's not like he can go get himself a snack whenever he gets a little hungry," Asui informed matter-of-factly from her perch on the far side of the couch.

"Please, do us a favor and never have kids," Jirou chimed in, earning a fresh growl of offense from Bakugo. Before another row could be sparked, Melissa stepped in to deflect.

"There's a couple more bottles of milk in the fridge. It should only take a minute to heat up for him," she said with a smile, beckoning Midoriya to follow her as she made her way into the kitchen. He followed eagerly, still holding Kansuke close even as the infant clung to his shirt. Once they were moving, however, those big blue eyes turned to look curiously around their new surroundings.

The kitchen was of generous size, meant to be shared among the twenty-one students occupying the dorm, yet every inch of its counter space seemed to be taken up by various mixing bowls and ingredients. Satou was manning the stove, cooking up what would soon be a hearty meal for his entire class, complete with dessert. Aoyama – having cleverly offered to help their more culinarily-inclined classmate with dinner to avoid the whole diaper fiasco earlier – glanced up from his own mixing bowl to offer Kansuke a flourish of a wave, pulling a delighted giggle from the infant. The sound was all it took to grab Satou's attention, and he looked over with a smile.

"Hey there, little guy. I'd give you a taste of what I'm making, but I think you gotta wait until you get some teeth in first," he joked warmly, continuing to gently stir a pot containing something that made Midoriya's mouth water from the smell alone. Meanwhile, Melissa had retrieved one of Kansuke's bottles from the fridge and approached the muscle-bound young hero.

"I don't suppose we could borrow a pot and one of the burners for a minute?" she asked, to which Satou could be seen visibly faltering. He glanced down at his fully occupied stovetop, looking back down at the blonde with a deeply apologetic look.

"S-sorry, that might take a little bit…"

Unfortunately, they didn't have that long to wait. Kansuke had spotted the familiar shape of his bottle and was currently reaching out towards it, making grabby hands and letting out a whine warning of yet more tears. Midoriya was familiar enough with the sound by now for it to raise a panic in him. He held the infant close, desperately rubbing at his back in effort to calm him, all the while shooting Melissa a desperate glance.

"Wh-what do we do now?" he questioned, to which Melissa could be seen furrowing her brow in thought.

"I dunno… He's pretty fussy about his milk, so I don't think he'll take it cold…" she mused aloud. Then, within moments, her face lit up in realization, and she turned out towards the common room once more.

"Hey, Shouto! Can you come here for a moment?"

When Todoroki entered the kitchen, he looked every bit as confused as Midoriya felt. This sense of confusion only deepened further for the both of them when Melissa passed the bottle over to the two-toned teen's left hand.

"Can you heat this up a little bit, please? It doesn't have to be much, just about to normal body temperature."

Once she made her request, Todoroki seemed to catch onto what she'd thought of. He stared down at the bottle in his hand, just the barest flash of flame engulfing it for a second before he held it out to her once more.

"Here, is that good enough?"

Melissa took the bottle back from him, holding it against her cheek to check the temperature. Once satisfied, a soft smile spread across her lips.

"It's perfect! Thanks!"

"Quel imbécile! Midoriya! Pay more attention when you're holding l'enfant!"

Midoriya jumped slightly in surprise at Aoyama's sudden interjection, having been momentarily distracted by Todoroki and Melissa. He glanced down at Kansuke in a cold panic, drawing in a sharp gasp when he saw the child. Somehow, though the young hero had held him securely against his chest the entire time, the infant had managed to grab a small plastic bowl from the island countertop and had dumped the entire contents over himself. He was now covered from head to toe in a layer of what looked like powdered sugar, his tiny fingers exploring the now empty bowl it once resided in.

"Oh no…" Melissa sighed out in exasperation, pulling a panicked yelp from Midoriya. He turned back towards her, his eyes wide and fearful that she may hate him for this.

"S-sorry! I only took my eyes off him for a second, I swear!"

In response to his feverish apology, the blonde merely smiled lightly and shook her head, stepping forward to hold out the bottle of warm milk to her baby brother. The bowl in Kansuke's hand may as well have ceased existing altogether the instant he spotted the bottle, dropping the former to grab hungrily at the latter. He wasted no time in shoving the nib of the bottle in his mouth when his sister finally handed it to him, falling into content silence as he drank.

"It's fine," Melissa assured gently. "He can be a handful sometimes. We'll just have to give him a bath once he's done eating."

A half hour later, Midoriya was in the boy's shared bathroom, Kansuke clinging to his shirt against his chest, babbling excitedly and bouncing in the teen's grasp as he watched the tub down below slowly start to fill up with water. With how fussy the infant was with most things, Izuku was grateful that he didn't seem to mind baths at all. He made sure to stop the water when it would be just high enough to cover the child's legs, just as he'd been told. He then laid him in his lap and started the surprisingly arduous task of peeling the powder-coated onesie off the squirming child.

"Jeez, don't you ever stop wiggling?" Izuku mumbled aloud to himself, though it was hard to stay annoyed when Kansuke was smiling happily up at him almost as though he was having the time of his life.

"Nope. He's been a little wiggle worm practically since Dad and Papa brought him home," came Melissa's amused commentary from somewhere behind him. He glanced over his shoulder in time to catch the blonde closing the bathroom door behind her, a fresh change of clothes for both himself and the infant tucked under one arm. Midoriya gave her a bashful smile, his cheeks heating up at the thought of her going into his room and seeing his walls covered ceiling to floor in posters of one of her own parents. God, she must think he was some obsessive freak… He supposed it was a fair accusation to make, if he was being perfectly honest with himself. Of course, if she found it odd at all she didn't show it.

Melissa set the clean clothes aside on the countertop before kneeling down in front of Izuku, lifting Kansuke out of his lap once he finally managed to wrestle the child's dirty clothes off. Once relieved of having to hold onto the infant, he rose up to his feet and took a few steps away, glancing shyly over his shoulder at Melissa as he took his own soiled shirt off. He knew he had nothing to be embarrassed about around her. After all, she'd seen him without a shirt before back on I-Island, and even if she hadn't she was suitably distracted with attending to her baby brother to pay him any mind. Still, he couldn't stop his cheeks from heating up at the thought, and he quickly changed into his new shirt.

"Hey, Izuku, could you lend me a hand for a sec?"

Midoriya jumped slightly in surprise when Melissa called out to him again. He peeked back at her, finding that she'd made quick work of undressing Kansuke the rest of the way and already had him in the bath.

"U-uh, s-sure! What do you need?" he asked nervously, still utterly at a loss for how he could be any help. That seemed to be the theme of the evening, of course. Melissa seemed to be a pro at everything to do with caring for a baby at this point, having been around to help and learn from her parents for over half a year now. Izuku, on the other hand, didn't have nearly as much experience. Sure, he'd held and played with Kansuke whenever he visited All Might's house, and he'd even asked the retired hero to show him a few things, but he was still more or less lost. Melissa seemed to pick up on that without trouble, giving him a reassuring smile as he returned to her side.

"Don't worry, it's nothing complicated. Can you just make sure he doesn't fall over while I wash him? He can't quite stay sitting up on his own yet."

Oh, well that did sound really simple. He was pretty sure he could manage that much. At least, that was his thought at first, before he knelt down and found himself pressed shoulder to shoulder with Melissa. He stiffened up, too afraid to risk moving an inch even as he held Kansuke steady in the bath.

Meanwhile, Melissa seemed not to notice their closeness at all, instead setting to work gingerly wiping the powdered sugar off the infant's face with a damp washcloth. Midoriya looked on, focusing on what she was doing if only to distract himself from the feeling of her shoulder pressed against his own.

"Man, you seem like a natural at this. Did you ever do babysitting before Kansuke was born?" he asked curiously, to which she let out a small chuckle.

"Nah, nothing like that. I mostly just learned from Dad and Papa. I knew some things in theory beforehand, of course, like how to hold him and how often he'd need to be fed. It's really not hard at all once you get used to it. I'm sure you'll be a pro here in a month or two if you keep at it like this."

Though he'd managed to recover in the past few moments, his cheeks reddened once more at that comment.

"Y-yeah, I guess I'd better learn while I can, huh?"

"Do you want to be a dad someday, Izuku?"

That last addition was enough to turn Midoriya's entire face beet red, and he sputtered for a moment in an effort to articulate a response. What was he so embarrassed about? It was a perfectly reasonable question to ask in this context, wasn't it? But to be asked something like that by such a pretty girl…

"Y-y-yeah, I g-guess I'd like that eventually. I never really gave it much thought before. I've always been so focused on becoming a hero that I never paid attention to anything else like that."

"Yeah, that sounds about right."

"Wh-what about you? Do you want kids eventually?"

Melissa paused to think about it for a moment, presumably having given the subject as little forethought as Midoriya himself had. She looked as though she was about to respond, but before she could, a splash of water hit her square in the face and soaking the front of her shirt, the culprit revealing himself with an amused giggle. Izuku instinctively looked over towards Melissa, his face heating up yet again when he spotted the effect the water had on the white fabric covering the other teen's chest.

"S-sorry!" he apologized frantically, quickly averting his eyes. Melissa merely laughed the incident off.

"It's fine. He likes to play in the bath, so I guess I should have given him a toy or something to keep him from splashing."

"I-I can let you borrow my shirt if you want…" he offered bashfully. Melissa gave him a perplexed look before finally looking down at herself, at which point her own cheeks flushed to match Izuku's own.

"O-oh! Y-yeah, that'd probably be a good idea..."

Finally, Kansuke was clean and quickly dressed, and soon the child was laying contently against Izuku's bare chest. He'd given Melissa his clean shirt to wear since her top had gotten soaked through, awkwardly taking his leave with her little brother in order to give her a bit of privacy to change. He made his way down the hall, absentmindedly heading towards his room, all the while Kansuke babbled softly against his shoulder. The young hero let out a weary laugh.

"You sure are talkative, huh?" he asked, earning him a soft cheek bap from a tiny hand. He let out another small chuckle before pushing his dorm's door open with his shoulder. As soon as they were inside, Kansuke suddenly let out a delighted squeal, reaching out with grabby hands at, well… everything. Izuku was heavily confused at first, at least until he realized what should have been obvious: every inch of his walls and every spare section of desktop was completely covered in memorabilia depicting the infant's own mother. He was surprised the kid was even able to recognize All Might in his muscle form, but he supposed there was something innately familiar about one's mother in the eyes of such a young child.

Unfortunately, Kansuke's initial delight seemed to fade into an upset desperation, a truly hurt whine escaping from him when the many visages of his parent didn't spring out of the posters to come hold him. Midoriya let out a panicked yelp, glancing around for something to distract the infant even as he rubbed at his back in an attempt to calm him. Fortunately, he rather quickly remembered something he kept tucked away, and soon enough he was sliding open the door to his closet, standing on the tips of his toes to reach into a box he kept stashed on the top shelf. Finally, his hand bumped against something soft and he grabbed hold of it.

What Izuku pulled out of the box was an old plush toy of his idol, all decked out in his Silver Age costume and bearing his trademark smile. It didn't hold any collectable value, having a few faded stains and re-stitched seams that any young child's favorite toy inevitably collected over the years. Kansuke didn't seem to mind that one bit, his eyes lighting up the instant the toy neared his face. His little hands grabbed fistfuls of threadbare cape, his face nuzzling lovingly against the old plush's chest as he held it close. Izuku couldn't help but smile warmly at how happy that simple old toy had made the child.

"Oh wow, I guess I shouldn't be surprised to see that you had that toy too, huh?"

Seemingly never able to catch a break, Midoriya let out a surprised yelp when he heard Melissa's voice behind him once more. He turned to her with his usual nervous smile, but his face turned beet red in an instant when he finally saw her. She'd changed out into the t-shirt he'd given her, but due to the few inches she had over him – in addition to her ample, err... chest – the bottom hem ended up hovering a good inch over where her pants sat on her waist, baring a bit of her midriff. He immediately averted his eyes to hide his embarrassment.

"S-sorry! I-I guess I should have realized my shirts wouldn't fit you right!" he apologized frantically. "I-I can go ask Yaoyorozu to make one that fits!"

Melissa glanced down at herself briefly, her cheeks growing slightly pink but her smile never fading.

"Nah, it's fine! I already put our clothes in the wash, so it's not like I'll be wearing it all night. Besides, it's really comfy!"

With that, she made her way over to his side, giving Kansuke's unruly rust-colored hair a soft rustle as he cooed lovingly to his new toy. Izuku tried to hide his blushing cheeks, but that was impossible to do with her standing so close, so he instead opted to change the subject.

"S-so you had this plush too? I-I didn't realize they sold All Might merch over in America."

"Yep! He was always super popular over there, even more so than most American heroes. I think the one I had came from Japan, though. Dad brought it as a gift during one of his visits. I kinda wish I still had it, but I ended up donating it once I grew out of keeping toys like that. I probably wouldn't have if I'd known who he really was to me back then..."

Ah, that's right. Izuku had almost forgotten that it had only been two years since Melissa was finally told that she was All Might's daughter. He still couldn't imagine what that must feel like; to never know that someone so close to you was really one of your parents. Granted, he himself probably only ever saw his own father as often as she'd seen the old hero, but at least he'd always known him as his dad.

"Oh wow, it's gotten pretty late already, huh?"

At that, Izuku was pulled from his thoughts, turning to glance back through his curtains to find that the sky had darkened to an inky black peppered with stars.

"O-oh, y-yeah, I guess that means you'd better head home soon, huh?" he stammered out, hoping she couldn't quite pick up on the disappointed note in his voice. As nervous as he was around her, he genuinely enjoyed her company, and helping to look after Kansuke wasn't so bad. Melissa hummed lightly in thought at that, staring at the curtain as though she could see her house from where she stood.

"Well, I mean it is Dad's birthday. I was kinda thinking of giving him and Papa a night where they don't have to wake up every few hours to feed a baby, y'know? So I guess I can sleep here tonight if that's alright with you guys. I'm sure Mr. Aizawa wouldn't have a problem with us staying in the common room for a night."

"Y-you can sleep in my bed if you want!"

Though the surprise in Melissa's eyes at that offer was clear, it paled in comparison to Midoriya's shock at his own words. He could feel all the blood drain from his face in an instant, his body going rigid and cold on him. What the hell was he saying?! He didn't even have time to think about it before he just blurted it out like that. But he couldn't just walk it back now. He had to follow through and find a way to not sound like a total creeper while doing so.

"I-I-I mean… Y-you're a guest, and i-it wouldn't be right to make you sleep on the couch. B-besides, none of the empty dorm rooms have beds, and even if they did Aizawa keeps them locked up since no one's living in them, a-and I can just grab a spare futon or something, and…"

As Izuku continued his habitual rambling, Melissa couldn't help but let out a light chuckle.

"That's very sweet of you, Izuku, but I'd feel so guilty if I took your bed from you. I can take the futon if that's okay. I wouldn't want Kansuke to accidentally roll off the bed in the night and hurt himself."

"I-I don't mind him sleeping with me!" he retorted instinctively. "I-I mean, I'm shorter, s-so it'd be easier for me to sleep on the floor anyway."

Melissa seemed to search his eyes for a moment, but soon enough relented with an amused chuckle.

"Well, alright then. I suppose I can't turn down an offer like that. Besides, Kan seems to really like you. Look, he's practically asleep already!"

At that, Izuku glanced down at the infant held in his arms. Kansuke lay with his head resting against the teen's shoulder, his eyes half closed, chewing groggily at the tip of one of the plush's bunny-ear bangs. The young hero smiled softly at that, wondering silently to himself if this was what being a big brother felt like.

"Thank you so much for watching him for us last night, I really appreciate it!" Dave said to more or less the whole class as Asui passed Kansuke off into All Might's arms. The infant let out a delighted squeal once he was in his mother's grasp, clinging to his t-shirt with an iron grip.

"No problem! It was kinda fun!" Uraraka beamed in reply for the lot of them.

"He wasn't any trouble, was he?" the old hero added, rubbing lightly at his son's back even as he snuggled close against his chest. The gathered students seemed to stumble over their response this time, many of them stammering something out over one another.

"N-no, not at all! He was a perfect angel!"

"Th-the most well-behaved kid on the planet, for sure!"

"Do we get paid next time?"

"Shut up, Mineta! You didn't even do anything!"

All Might let out a small chuckle at that. Ah, it seemed his little Kansuke really put them to the test last night. He felt a little bad, but at the same time it would do the lot of them some good to learn to care for young children, even if some of them didn't go on to become parents themselves. Of course, it seemed one among them had been given the full overnight course.

Midoriya sat on the arm of one of the couches, leaning with his shoulder and head propped up against the back, his eyes slightly sunken and staring off into the middle distance, presumably unaware of what was going on around him. Thinking back on how often Kansuke tended to wake up at night and adding a few for him sleeping in a new place for the first time, All Might was certain the poor teen hadn't gotten more than an hour or two of solid sleep the night before. Even so, he doubted he'd ever hear a word of complaint from his young successor, even if he hadn't been too tired to do so. He'd have to think up some way to repay him for his extra effort.
