#BKDK, A!Kacchan, O!Izuku college au sorta jock/nerd

There's a knock at Izuku's door, prompting him to look up from his trig homework he's been staring blankly at for the past twenty minutes. His friends, who are truly being no help, stop eating the popcorn they've been stuffing
2
their mouths with to stare at the door.

"You get it," Izuku huffs, returning his eyes to his homework. Ochako grunts, slapping her hand on her iPad, which is playing classical music.

"/You/ get it! It's your dorm," Izuku levels her with an unimpressed stare, holding it
3
and not moving. Ochako doesn't move either, even as another rap of knocks echo.

Finally, Tsuyu moves with a grumble and stands, opening the door while huffing under her breath about what brats they are.

Izuku giggles, but leaves his homework alone, curious to see who is at
4
his door on a random Sunday at two pm.

He's expecting Todoroki, or maybe Shinsou, /not/ the hottest Alpha on campus.

Bakugou Katsuki.

Izuku's pencil hits his little kotatsu table and rolls off, staring at the large blond who looms over Tsuyu with such an imposing presence
5
Izuki shivers from twenty feet away.

"Oi," The single word shocks Tsuyu into stumbling back; whether to let the blond in or to get out of the way, Izuku doesn't know. "You," One of those big hands points at Izuku, making his heart stop in his chest.

Oh god, is he gonna die?
6
"M-Me...?" Izuku asks meekly, hoping he's actually pointing at Iida, who is sitting right next to him.

"Who the fuck else?" Katsuki grunts, walking into his room and avoiding the little carpet they have set out as he crosses the room in four big strides.

/Eek/.
7
"U-Uhm, ca-can I help you...?" Izuku whispers, staring up at the blond who is now just standing over him in his full six-foot-five glory, varsity jacket hanging off those broad shoulders and framing a chiseled body.

/Ho there, Izuku... hold your horses./

A smirk crawls on
8
the Alpha's face, flaxen lashes hiding carmine eyes so bright Izuku could get lost in them. The blond crouches down, slapping a bag stained in grease and smelling suspiciously like Izuku's favorite ramen place he hasn't been able to go to due to money problems.

"Is that...?"
9
Izuku can feel his mouth flooding with drool, staring at the takeout bag.

"Ramen from your favorite place? Yes, it is," Izuku didn't even notice how the blond reached out and tilted his head up, eyes ripped away from the takeout bag to stare into sharp carmine eyes that have
10
invaded his dreams for months.

"But... why?" Izuku gulps, knowing he and the blond have only crossed paths a handful of times.

"Take this as my initiative in courting your oblivious ass," The blond chuckles.

Izuku /blue screens/.
11
As if he didn't turn Izuku's world on it's side, Katsuki stands up, ruffles his hair--leaving his /scent/ in his curls, and walks off.

Izuku falls backward like a goat playing dead, staring up at his ceiling before jumping into action, hitting his knee on his kotatsu in the
12
process.

"UHM!" Izuku squeaks, throwing himself into the hallway, swinging out wide with the only anchor being his hand on his doorstep. Katsuki stops, looking over his shoulder at Izuku with such a simple but /hot/ look it makes Izuku's knees weak.
13
"D-Do you? Uhm! Uh!" Izuku cannot think straight, trying not to fall over.

Katsuki has the gall to laugh at him, turning on his heels as his hands stuff in his jacket pockets. "Yes to whatever question you're trying to conjure up in your mind. My number is in the bag, nerd,"
14
With a quick grin and an even quicker wink, Katsuki swaggers off like he hasn't just made every dream Izuku's ever had since seeing the blond come true.

"Eat your food before it gets cold!" Izuku startles at the shout before the blond rounds the corner and disappears.
15
Right on time, his stomach gurgles as he dazedly walks into his dorm room, shuts the door behind him, and digs into the food he's been missing for /months/.

-

Katsuki slides down the wall, unable to keep the smile off his face any longer. Holy fuck he just did that!
16
Pulling his phone out, Katsuki tries to shake off the jitters rushing through his entire body, inner bastard howling and screaming in his ear about finally manning up.

He stares at his phone, looking at the many missed texts from Shitty hair. He clicks on one, watching them
17
all load in. Eijirou's been nervous for the /both/ of them, with enough anxiety to go around tenfold.

[Katsuki: I did it]

He sets his phone back in his pocket, ignoring how the vibrations pick up once more as he buries his head into his hands,
18
grinning like an absolute /idiot/.

He did it.

HE FUCKING DID IT! He asked--more like /proclaimed/--that he is going to court Deku!

HAH! Take that Dunce face! Pisshead dared to bet against his ability to ask Deku out like he was /weak/. But he's not, and he's /hopefully/ going
19
to get a text from his dream husband soon.

After the nerd's brain reboots.

Almost on time, a high-pitched squeal echoes down the hallway, making Katsuki chuckle and shake his head as he stands up. For his success, he's going to treat himself to some spicy ramen.
20
And then claim his bet money from Dunceface.
21
-
end. smh cute! also no, telling deku's he's courting him wasn't a bet! he's liked izuku for a while but kaminari decided to start a bet to see when/if bkg was gonna confess! katsukis gonna bleed him dry loool

ko-fi.com/tiredneedssleep
22
[a/n: a goal has been posted on my kofi! will update when its reached]
23
Katsuki walks out of Deku's dorm room, trying to keep the grin off his face as he starts the quick and easy walk across campus to his car. He's hoping none of his idiots--friends--are in the courtyard, as then he'll be ambushed.

He's sure Eijirou's already spread the news
24
around their groupchat--known as the "bakusquad", although Dunce face is a lover of changing the name often--and he's pretty sure that's why his phone hasn't stopped buzzing in his jacket's pocket since he sent the text.

It's a bit annoying but nothing out of the ordinary,
25
as they often spam the groupchat to get his attention. It's not going to work this time, though, as he's hellbent on getting his fucking spicy ramen before answering any of those gossip heathens.

He loves the idiots--to a degree--but they are like sharks after the waters has
26
been chummed. Bloodthirsty and tearing apart any droplet of gossip or drama that bleeds into the water.

Katsuki does /not/ want to deal with that currently, thank you very much. He'll fill the idiots in on how everything went /later/.

-

Crossing the courtyard is easy, as he
27
hasn't been ambushed or tackled by the idiots he calls his packmates. He makes it to his car with ease, sliding into the sleek Mustang, turning it on, and hearing the engine rumble.

Katsuki sits for a moment, feeling the AC blow over him as his car locks. Finally, he tosses
28
his phone into the center console, burying his head in his hands, unable to control his grin any longer. His face splits into a wide smile he's been fighting since he /left/ the dorms.

Nobody needs to see Bakugou Katsuki smile. Except for Deku, of course. That's reserved
29
just for him.

"I did it... I FUCKING DID IT!" Katsuki throws his head back, pumping his fists up and grunting softly as they hit the ceiling of his car. Anxiety and /excitement/ pump through him, his car smelling of woodsmoke, sugar, and bourbon.
30
He can't help it, especially when he's in his car, with nobody around to hear, see, or smell his freak out.

He feels like a little kid again, seeing a pretty boy across the playground and freaking out. Only, this time, it's a /good/ freakout.
31
"Okay, okay," Katsuki chuckles to himself, hands on his steering wheel, practically strangling it as he breathes in and out. "Reel yourself in, lets get food," Katsuki breathes out once more, ignoring the wall of texts on his phone as he punches in the address on his directions
32
app.

It quickly starts the route, an automated voice echoing through his speakers as he backs out of his parking spot. Following the directions as he drives off campus, his left foot taps away out of excitement as he bobs his head to his music, exuding happiness.

-
33
Izuku finishes his ramen with one last slurp of noodles, setting his chopsticks into the mostly empty bowl. He's been eating it throughout his and his friend's study session, although they are all long gone by now.

"That hit the spot," Izuku sighs happily, patting his belly.
34
Even through the four reheats, it's still as delicious as always. The noodles tasting still so fresh, and the broth as warm and flavorful as it was when he first poured it.

Izuku's eyes slowly crack open, zeroing in on the bag that the ramen came in.

/My number is in the bag./
35
Izuku remembers Bakugou's words, tummy flipping and buzzing with a funny feeling as he sits up. His kotatsu has turned off, but his feet are still nice and warm underneath, heat still trapped inside.

"I'll just... take a peek..." Izuku reasons with himself, phone next to him as
36
he pulls the empty bag forward, gulping softly.

Inside the bag is an extra set of chopsticks, a plastic spoon, and a handful of napkins.

His stomach droops, sadness filling him. Is it actually in here, or was this some sick joke?

No, Izuku refuses to think Bakugou would do
37
that!

He digs around the bag, pulling the napkins out and realizing the number is on one of them, scrawled out semi-messily but still good enough to read. As expected of Bakugou, even writing on a napkin seems easy for him!

"Do I...? I mean, he put it here for a reason!"
38
Izuku fights with himself before grabbing his phone and entering the number before he can take it back, sending a quick and simple text thanking the Alpha for the ramen before he can chicken out.

He debates sending more, deleting and retyping his text too many times to count.

-
39
Katsuki chuckles, watching those little three grey dots disappear, only to reappear just moments later. Deku's /clearly/ freaking out, like usual. Katsuki thinks he ought to bite the bullet for him and get it over with.

[Oi]

The text is simple and those grey dots vanish,
40
but Katsuki doesn't let that bother him, leaning back in his desk chair as he ignores the idiots that have barged into his dorm room and refused to leave unless they got details on the whole thing.

[Are you free tuesday? Dinner or movie, your choice]

Katsuki sends the text,
41
ignoring the hollow pit of anxiety in his stomach. The text is read milliseconds after it's delivered and it's quickly followed by a string of words and numbers, a 'keysmash' as Dunce face likes to call it.

[I'll take that as a yes. Lemme know what you wanna do, we can go
42
wherever you want] Katsuki sends the text and closes his phone, staring at Dunce face's wallet on his desk.

Well, time to collect his bet money.
43

TBC~ fufufu katsuki u smooth fox u

so sorry this update is a day late! tbh I had no brain power n forgot and it took me more time today because I hated how I wrote half of the update last night LOL

there's a goal on my kofi! once it's met, I'll update! ko-fi.com/tiredneedssleep
44
Katsuki pulls the crisp bills from Dunce Face's wallet, snapping it close and alerting all his friends. They all look to him as Katsuki counts the bills, finding its the exact amount the idiot's bet on him never being able to confess to Deku.

Losers.
45
"Hey! What are you doing with my money?!" Dunce face squawks, pointing at Katsuki as he scrambles off the bed, getting caught up in his blankets as he does, barely keeping himself from falling face-first into the ground.

"Collecting on my bet money, idiot,"
46
Katsuki snarks, tossing the empty wallet at Dunce face, cackling when it smacks the fumbling idiot in the face. "You'll be funding my date on Tuesday," Katsuki pockets the money in his own wallet, placing it in between the bills already in there, grinning as he closes it before
47
stuffing it into his hoodie pocket.

"HAHHH??? You actually /did/ it?! Are you kidding me?" Dunce face deflates, keeling over as he lays on his floor, looking defeated. "And to think I bet so much on you not being able to confess..." Dunce face cries weakly, covering his face in
48
shame.

"Aw, cheer up, Denki! We'll spot you for meals for now," Eijirou smiles happily, patting the wallowing beta on the floor. "I mean, we did bet against /Bakugou/ of all people; that was kind of stupid..." Ei huffs, getting a wallowed groan from Dunce face.
49
"Whose side are you on, Kiri?!" Dunce face whines, popping up from the floor to glare at the chuckling Alpha.

"Anyway, what's he like? We haven't exactly met this mysterious Omega you decided to court out of the blue," Soy sauce hums, looking at Katsuki.
50
Katsuki cringes, leaning back in his chair. He forgot how gossip hungry Sero was, as Dunce face and Pinky had corrupted the once neutral man.

"I think it's time for you all to get the fuck outta' my dorm. Don't you guys have exams to study for?" Katsuki can see the
51
horror settle on all of their faces, shoulders all slumping forward.

"You play dirty, man... /dirty/," Soy sauce sighs as they all slowly filter out, making Katsuki snicker, watching Dunce face and Soy sauce close the door behind them, like the good idiots Katsuki taught them
52
to be.

"Not a word, Ei," Katsuki says as he leans forward in his chair, eyeing his roommate, who sticks his hands up in mock defeat.

"My lips are sealed, bro. Swear! Haven't even told Mina about him!" Eijirou chuckles as he stands from Katsuki's bed and walks to his own,
53
flopping down and eyeing Katsuki as the blond texts on his phone, finally managing to get replies from Deku, who has gently said a movie date would be fun.

"So.... what are you going to wear to your date?" Ei asks, making Katsuki groan.

"I will kick your ass out, Ei,"
54
"Hey! It's my dorm too!"

-

Izuku nervously awaits Katsuki's arrival, licking his lips and cleaning his dorm for the fourth time.

Seeing as he has a dorm all to himself, they decided instead of going to do the movies, Katsuki would pick food up for them, and
55
they'd watch movies in Izuku's dorm.

He's a bit nervous--of /course/ he's nervous, he's never been on a date before! Especially with such a hot Alpha!--and he can't help the way he rolls his fingers and tries to keep himself from picking at them, instead picking at the little
56
pills on the inside of his pants, keeping himself as busy as possible as the minutes tick past.

"Earth to nerd," Izuku screams when Katsuki suddenly appears next to him, nearly falling off his bed.

"WAAH-chuki! You scared me!" Izuku whines, staring at the blond who looks to be
57
holding back his laughs, but it doesn't work as the blond quickly turns away, snickering and coughing into the crook of his arm.

"Sorry, your door was open, so I just decided to come in," Katsuki chuckles, patting him on the arm--the one he grabbed to keep Izuku from flinging
58
himself off his bed in fright--before holding up the back with takeout.

"You got the goods?" Izuku whispered, already drooling at the smell of the delicious takeout swinging idly in front of him. He holds himself back, keeping his mouth closed to not let any drool out.
59
"You're ridiculous, but yes, I did," Katsuki chuckles, setting them on his kotatsu, which Izuku has set up with a jar of water and two glasses. His monitor is situated away from his wall on the stand it's on, acting as the TV.
60
"I ain't gonna bite, nerd, c'mere," Katsuki huffs, rolling his eyes and pushing the pillow next to him out slightly so Izuku can slide off his bed and sit down next to him, watching the Alpha pull all the takeout out, dividing up the goods.

Katsudon for him, and stirfry for
61
Katsuki.

"Whaddya' wanna watch?" Katsuki hums, already taking a forkful of fried rice, staring at Izuku as he uses his wireless mouse to scroll through the movies he has.

"Do you like All Might?" Izuku asks, looking at the blond who raises an eyebrow.
62
"Nerd, I have tattoos of All Might in plain view, of /course/ I do," Katsuki points his fork at him, and Izuku is /definitely/ falling in love.

"From the beginning of the trilogy?" Izuku asks, trying to keep the love out of his voice as he realizes he's found his soulmate.
63
"From the beginning of the universe, nerd. We don't skip the first movie ever, even if it was originally a stand-alone," Katsuki chuckles, eating more of his fried rice as Izuku's scent suddenly blooms sweetly, full of /happiness/.

"I've never met someone who knew that,"
64
Izuku whispers, falling deeper in love with the blond who grins at him, not a hint of snark or pride in that grin.

It's genuine, and Izuku could almost fathom to call it a /smile/.

Bakugou Katsuki is /smiling/ at him.

"Well, now you have, nerd. I'm gonna knock your damn socks
65
"off with my knowledge," Katsuki grins, leaning forward and letting Izuku smell the rich scent of woodsmoke and bourbon wafting off of him. "Plus, if you keep smelling like that, I might even have to deduce you /like/ me," Izuku can feel a ripple go through his body, licking his
66
lips, very aware of the blond's sharp red eyes following the motion.

"I never coined you for a nerd, Kacchan," Izuku whispers, getting even closer to the blond, who does the same. Their noses are brushing gently, eyes locked.

"Not a mega nerd like you are, though,"
67
The blond snorts, "and, Kacchan? Really?" The Alpha tilts his head gently as Izuku can feel a smile bloom on his face, unable to keep it down anymore.

"What? You call me Deku, so I have to find a nickname for you," Izuku chuckles, watching the blond hum.
68
"And a mega nerd, really? You didn't deny being a nerd, though. I can't believe Bakugou Katsuki is a nerd," Izuku grins at how the blond's cheeks flush gently, glaring down at him with no actual malice.

"Well, if you keep this shit up, you'll learn lots more about me,"
69
Katsuki whispers, grinning as he gets so close, Izuku can feel the air wafting against his lips.

"Now, are we gonna watch the movies and eat our food, or are we gonna make out on your floor?" The blond purrs, making Izuku flush.

He seriously debates both options,
70
nibbling at his lip before his stomach plainly decides for him.

/GUUUURRRGLLEEE/

Kacchan barks a laugh, pulling away from Izuku, who momentarily mourns the loss as he holds his stomach, blushing to high heaven.

"I think your body decided for ya, Deku,"
71
Kacchan snorts, pushing his takeout box toward him. "Now, eat, and let's watch All Might fucken' rock,"

Oh yeah, Izuku's in love.

So totally in love.
72

TBC~ they are losers ur honor.... such losers LOOOLL

honestly I didn't think id hit (and go /over/) tweet limit but my mind had other ideas for me lo

there's a goal on my kofi! once it's met, I'll update! ty for all the support so far <3! ko-fi.com/tiredneedssleep
73
“Uwaaah, that hit the spot!” Deku giggles, patting his tummy as he leans against his bed. Katsuki watches the Omega, who reeks of /happy, happy, satiated/. It makes Katsuki preen, chest puffing up subconsciously as Deku’s eyes slide close, preening like a cat who got the canary.
74
Or a nerd who got his katsudon.

Katsuki snorts to himself at the comparison, shaking his head and closing his eyes for a brief moment before opening them up once more and finding Deku looking at him, a gentle tilt to his head. “What are you laughing at?”
75
Deku grumbles, pouting and suddenly sitting up straight. It strikes a chord with Katsuki, who licks his lips and tries to keep the wince tamped down as he leans back, stuffed as well. His stirfry was so fucking good that he ate the whole damn thing,
76
which prompted him to pop the button on his jeans.

“Nothing, just something cute,” Katsuki hums, watching Deku’s eyes flick away, heat rushing to his cheeks, tinting them a pretty pink. Katsuki thinks they look like sakura mochi, and /fuck/, he wants to bite them.
77
He can’t help it, alright? Alpha’s have a natural urge to /bite/, and Deku’s looks real fucken’ chompable right now.

“Suure,” Deku puffs out, closing in on himself.

Well, fuck.

Katsuki’s quick to lean over, pulling himself out from under the table and right next to Deku,
78
bumping knees with the smaller Omega, who jolts at the sudden touch. Deku’s peering up at him through thick, dewy lashes, already shining with tears. Katsuki hates it when Deku cries. Especially when it’s because of /him/.

“Hey,” Katsuki huffs, trying to keep his voice soft
79
as best he can, although the rumble in his voice doesn’t go away, but smooths out. “I really wasn’t laughing at you; I just made a stupid joke in my head, I swear. Nothing bad, I promise,” Katsuki hums, pulling his legs up to settle his arms around his knees loosely,
80
watching Deku shy away from his gaze, picking at his fingers. Katsuki’s realized this as a nervous tick of Deku’s from their occasional study sessions–as that’s where he and Deku actually /met/–and brings his hand over to set it atop Deku’s, linking their hands together
81
and stopping the nervous picking.

“You promise?” Deku asks, hand shaking gently under his. He’s so… delicate.

Katsuki thinks he’s even more beautiful to him.

“I promise, swear on my life n’ All Might knowledge,” Katsuki snorts, getting a giggle out of Deku as well,
82
the tension melting away like an ice cube on a hot day.

“You are such a nerd,” Deku giggles, poking his hand and making Katsuki mock-gasp. He glares playfully at the Omega, who sticks his tongue out at him.

Katsuki takes that to run his hand down Deku’s leg and pull him off
83
balance, pulling him toward Katsuki as Deku flails and squawks at him, gulping so loud that Katsuki can /hear/ it as he leans over the blushing Omega, hands on either side of his body.

“K-Kacchan,” Deku wheezes, as red as a cherry, as he looks up at Katsuki,
84
who grins down at him.

“Hm?” Katsuki hums, leaning further down, torso twisted to face Deku while his legs still splayed to the side. He’s staring into Deku’s eyes, losing himself in the green valley hiding behind fluttering lashes.
85
His hands are loose on the ground and Deku could have easily moved by now, but he’s not. Instead, he’s staying right where Katsuki pulled him to and stares up at him, face as red as ever.

“Y-You play dirty,” Deku grumps, lips pulling into a pout,
86
arms raising to loop gently around Katsuki’s neck, fingernails scratching the little baby hairs on the back of his neck, making him shiver. Deku’s so /close/ to his scent gland that Katsuki can’t help the way he swallows nervously, and his body shifts,
87
trying to ignore the radiating warmth coming from Deku’s forearm. It’s hovering so close to his neck that if Katsuki moved /juuust/ slightly, he could scent Deku.

God, he wants to. He wants Deku walking around smelling like a combination of the two of them.

/Fuck/.
88
“You’ve found me out,” Katsuki quips, joking as Deku rolls his eyes playfully, gathering a fingerful of strands between two digits and tugging them. Katsuki grunts but doesn’t let it phase him too much, as he knows the nerd didn’t mean for it to hurt, and it didn’t.
89
“What ever shall you do, Deku? You’re trapped, all according to my evil, evil plan,” Katsuki snorts, leaning further down, thanking the gods he does not skimp on arm days. His muscles hold him up easily, watching Deku flush deeper as he lowers himself.
90
“A nerd /and/ a roleplayer? Kacchan, you surprise me every day,” Deku quips back, a smug little grin forming on his face as Katsuki nearly loses his composure, dropping an inch or two in his shock and /betrayal/.

“O-OI! Fuck you!” Katsuki barks, a flush painting itself on the
91
highs of his cheeks as he glares down at the laughing Omega. “Just for that…” Katsuki grumbles, lowering himself down all the way, squishing Deku under his torso, weight fully bearing down on him.

“A-Ack! Kacchan! Heavy!” Deku squeaks, slapping at his shoulders,
92
but Katsuki doesn’t relent, laying his head on Deku’s chest as he watches and feels the Omega wriggle and squirm under him.

“Serves you right,” Katsuki grumbles, watching Deku slowly settle, pouting down at him as Katsuki wraps his arms around the Omega,
93
working his hands up and down the nerd’s sides slowly. Deku shivers but doesn’t do anything, staring down at him and readjusting his arms around Katsuki’s neck and on his shoulders, fingers getting lost in his hair. It’s quiet for a moment, nothing but the rolling credits of the
94
first movie in the background as they stare at each other.

“Does that offer for a makeout session still stand?” Deku asks out of the blue, startling Katsuki and making him choke on his damn spit. He raises both eyebrows at the nerd, so high they nearly disappear into his
95
hairline.

“I guess we’re finding different things out about each other, never pegged you for being /bold/, Deku,” Katsuki chuckles, pulling himself up and forward, face-to-face with Deku, who blushes and looks away, embarrassed. He probably didn’t mean to say that,
96
but Katsuki is taking /full/ advantage of it.

“H-Hey! You offered it in the first place!” Deku squeaks as Katsuki gets closer, their noses brushing together. This close, Katsuki can smell the undernotes of Deku’s scent, the creeping petrichor, and honey under ozone and pine.
97
He smells /fantastic/.

“I never said I was refusing, Deku,” Katsuki purrs, leaning down and licking his lips, so close that their breaths mingle and Deku’s flitting eyes finally focus on /him/.

Yeah, that’s right… Keep your eyes on /him/, Deku.
98
“T-Then, make due on your acceptance,” Deku pouts, tugging him down as far as he can go without crashing their lips together. “Before I melt into the floor, please,” Deku adds, cheeks as red as ever.

“With fucking /pleasure,/”
99

Katsuki grins, leaning down and sealing their first kiss of /many/.

Oh yeah, Katsuki is in fucking love.
