Birthday gifts

Summary:

After Izuku’s chaotic birthday party, and a lot of amazing surprises, Izuku plays Tomadaichi life and gets absolutely obsessed. He’s so invested he made the entire class 3A into his game.

He went to go show Katsuki his versions of them but little does he know the characters he made of them decide they’re getting married?!

“Here ya go Midoriya!” Denki playfully shoved the game case encapsulating the disc into Izuku’s hands.

“Awh thanks Kaminari” Izuku smiled at him before inspecting the game. Oh wait he needed a Nintendo to play this?! He wasn’t gonna say that he didn’t have one to the gleaming Denki at his side though so he grinned up at him and placed it on the table of gifts he had wracked up for his 18th birthday.

“Thanks guys but that’s wraps. I’m so tired now” Izuku stretched out his arms behind him as stood up to gather up the gifts into a larger gift bag in curtesy of YaMomo making it quickly so that it’d be easier to take them up to his room.

It had been a fun night, since they’d surprised him when he came back from some extra solo training.

As soon as he had entered the dorm building they popped streamers into his face and dragged him into all sorts of activities he’d never experienced before such as karaoke which Jirou heavily assisted in improving his absolute atrocious vocal skills but thanks to her help he could say he wasn’t a screeching mess anymore!

They’d played games in which he cooked Kirishima up way too hard and then a whole dance battle which of course he had Mina on his team as he was the privileged birthday boy who deserved his guaranteed win.

However since the party started at 8pm Kacchan wasn’t there due to his strict sleep schedule but Izuku was made aware that all the food that had been served was made by him so he took extra time in munching up his food, savouring the warm feelings that he had because he was eating Kacchan’s cooking.

Then cake was served up thanks to Sato and it was super delicious, exactly right to eat before opening up his gifts. It was somehow 12am and he was out of energy though.

“Not so fast Midobro we got a special last segment for this certain day!” Kirishima grinned mischievously at him before pulling out a bottle of what looked like-vodka?!

“Kirishima! I told you that as class representative I was not gonna let you go through with this!” Iida immediately yelled whilst doing his usual robotic hand gestures.

“Haha no way Kirishima you actually snuck that in” Uraraka giggled as she playfully nudged Iida out of the way to inspect the bottle.

“Well it’s his 18th birthday and it’s legal now right? I thought he might wanna try it for his first time, only if you’re up to it though Midobro!”

“Hmm, I guess a little sip wouldn’t hurt…” Izuku stared at the bottle intrigued.

“That’s cold, he can’t do it alone, I’ll do it with you for moral support Midoriya” Todoroki suggested to which Izuku grinned at him.

“Ahhh hell yeah I’ll do it too for this special occasion!” Denki volunteered.

“No I’m sorry dear classmates you cannot do this!” Iida continued to protest but as a few murmurs went around the room the class came to a final decision.

Iida looked at them all in dismay for a second knowing they were coming up with a scheme to not let him stop them but before he knew it Sero’s tape had been wrapped around him quickly restraining him. “This is no order!”

Izuku apologetically smiled at him “sorry, Iida I promise not to get tipsy!”

“Ah, if the birthday day boy wants to I guess…”

“Atta boy!” Kirishima cried getting his own drink. Now Kirishima, Todoroki, Denki and Izuku had their glasses filled up before everyone did a countdown.

“3…2….1!”

They all chugged their glasses in one whole gulp and woah Izuku felt the burn in his throat.

“Oh shit that burns!”

“Doesn’t it though?” Kirishima cheered.

“Oof I don’t know how I’m gonna walk!” Izuku walked around dizzily.

“Oh no is Midoriya gonna be a light weight?” Uraraka giggled as she went to go adjust Izuku so he wouldn’t trip on his two feet.

“I feel fine to be honest” Todoroki said the effect of alcohol not getting to him at all, Denki on the other hand…

“GUYS, THAT WAS KILLER!”

“Oh no it might’ve subconsciously activated his quirk his brains gone bye bye!” Jirou cackled as YaMomo supported her from behind.

Everyone was laughing now at the sight of the poor Izuku struggling to walk and mumbling but mostly Denki who was babbling gibberish at this point until a certain someone stomped down the stairs.

“WHY IS EVERYONE STILL HERE?!”

“Oof it’s Kacchan hahahahaha” Izuku exasperated pointing at him before almost stumbling on his feet.

“Oh my gosh” Katsuki wiped his face before walking over to Izuku and putting his arm on his shoulder and then wrapping his other arm around the stumbling boys waist before giving Kirishima the stink eye.

“Hey don’t look at me! I just made sure Midoriya had the choice to try it since it’s his very special day and the day he turned legal! It was so manly!”. Kirishima cried out dramatically.

“Ugh whatever shitty hair I can’t believe all of you kept him here for this long! I’m taking him up before you buffoons keep him here any longer!” Katsuki said grabbing the gift bag on the table (evidently Izuku hadn’t made it too far after drinking his first drink even though to the boy it seemed he’d walked a mile).

As Katsuki and Izuku made their way up the stairs Iida finally burst out of his restraints and started lecturing the class and then they all started cleaning up some of the messes they made.

“Wait Kacchan what’re you doing here?”

“I was sleeping but the ruckus downstairs woke me up! Damn bastards said they’d been done after 10pm, sue me for believing a word any of them said! Ugh if I knew that they’d go through with actually even offering you a drink I would’ve been there dammit”.

“Kacchan stop being a party pooper! You could’ve been there the whole time if you didn’t have such a grandpa sleep shedule!” Izuku burst out laughing at his own joke.

“This is why I’m going to surpass you, idiot”.

“No you’re not!”

“Whatever you say nerd shut up before I explode you!”

“Yeah yeah Kacchan” Izuku was receiving help to walk right now so he wasn’t aware that they were so close to his room until they were actually there.

“Thanks Kacchan!” Izuku smiled but as he opened the door Katsuki followed him in. Izuku confusingly stared at him.

“Since I got woken up I decided I might as well see your reaction to my gift” Katsuki casually stated before his eyes drifted behind Izuku which made Izuku follow his gaze until he saw a wrapped up rectangle on his bed.

That distracted Izuku really quick. “Oooh I wonder what it is” as he rushed over to his bed and ripped open the packaging and that was where he saw it. A Nintendo!

“Oh my gosh did you and Kaminari plan this?”.

“Well the idiot wanted to get that weird game for ya but I knew you didn’t have a Nintendo but wouldn’t say it because you’re too nice so I thought it’d be good for the last gift because you know the best should always be saved for last”. Katsuki smirked at Izuku’s twinkling eyes.

“Awhh thanks”. Izuku huffed looking through his bag to find the Tomadaichi game before Katsuki abruptly ruffled his hair and then used two fingers that pressed into his forehead to push his head onto the pillow.

“Don’t play the game now nerd! Get some sleep you probably won’t wake up with a hangover since it was only a glass amount but still”.

“Ok fine”. Izuku quickly cuddled up on his pillow as the sheer exhaustion he felt was being brought out his body as he sunk into his bed and snuggled onto all the softness of his pillows around him.

Katsuki inspected him for a moment before making his way to the door. “Good”. Then he slipped out into the hallway.

As sleep overtook him, Izuku dreamt about building his ideas for the game once he woke up.

 

——

 

It was a few hours into the next day when Izuku was hooked into the game. He couldn’t stop. He’d designed most of the classes characters and it was so cute how they interacted with each other!

He made his own Mii (everyone was technically called a Mii) which was a little hard since he didn’t have the best artistic skills but he drew up a face which was accurate enough, evidently the scar was a little wobbly but that was fine. That was nothing compared to the squiggle he had put on Katsuki’s face. Izuku giggled when he saw the two of them interacting.

The game had a lot of little animation scenes that they found themselves in more than the others and right now the arrows pointing to each other said they were super close! That was fairly positive of course although at first their characters didn’t get along.

Perhaps that’s why Izuku was grinding on the game but he made a lot of progess with the “Kacchan” and “Deku” in the game—he saved them that way since it was more familiar to him.

Izuku tried making the interior of the school in parts of his island so he moved to the common room and got to work whilst he layed on the sofa, the screen glued to his face.

It was actually not as hard as he thought and it was coming together smoothly!

So instead he went back to see what “Deku” and “Kacchan” were doing and they were having a stroll in the park when all of a sudden it seemed that “Kacchan” was going to fall into a puddle. Oh no could he stop it? Well Izuku couldn’t but this “Deku” could.

Izuku watched as his screen transformed the camera angle and he watched as his Mii went and threw himself flat faced into the puddle before “Kacchan” could step in it. A little sound effect of glitter and sparkles were going off in the back. “Thanks” the “Kacchan” deadpanned.

Izuku giggled at the gesture, thankfully he was heroic enough in this game as he was in real life.

Izuku sought to it that he didn’t neglect his Mii interactions with his other classmates even thought it was just a game but he wanted to maintain the balance so he got his Mii to walk around with Todoroki for a little. It was also hard to make his character since it was half and half colours but he managed.

However soon enough his Mii found his way to “Kacchan” who was eating pudding at a cafe with “Uraraka” hmm that was funny.

After that “Deku” and “Kacchan” found themselves going to a different place. They were oddly magnetically attracted to each other. Ha he realised he should probably show this to the real Kacchan since he’d probably explode from how nice this “Kacchan” was being so Izuku stalked up the stairs and back into the hallway of Katsuki’s room and knocked impatiently on the door.

“Kacchan, open the door!” Izuku yelled.

The door swung open after a second. “Huh, what’s up Izuku? I went downstairs a few minutes ago and your face was literally peeled to that screen, you didn’t even notice me walk in the room you damn nerd and here you are still clutching onto it!” Katsuki ruffled Izuku’s hair for the Nth time that week.

Izuku didn’t realise how wrapped up he must’ve been in the game because he didn’t even think that others he would’ve normally acknowledged would’ve walked into the common room since it was literally the COMMON room, yikes Tomadaichi life was proving to be an addiction that was too good.

“Awh man I really should’ve payed more attention to my surrounds sorry Kacchan!”.

“It’s whatever nerd, you clearly like the game so appreciate my gift even more because without it you wouldn’t be playing it!”. Katsuki huffed a little laugh.

“Well yeah I do! It’s really cool but it seems our Miis can’t stop following each other so I thought I’d come show you!”

Katsuki ogled at him. “Our what? Huh? What is a Mii?”.

Izuku just stepped past Katsuki into the room and sat on his bed and showed him the screen.

“Oi, I didn’t invite you in here” Katsuki said that but he still closed the door and moved to sit next to Izuku on the bed.

“Look it’s “Kacchan” and “Deku”!” Izuku moved the switch screen in the middle so they could both see and it was a scene where “Kacchan” and “Deku” were now going to the cinema.

“What the shit is that us?! Stalker nerd what is this?!”

“Don’t be so flattered Kacchan I made the whole class!” Izuku point at the screen to show the other Miis of their classmates sitting in the movie theatre with them. “But our Miis just keep finding each other like it really gets to a point ya know?”

“Damn even in this world you don’t seem to leave me alone” Katsuki softly spoke still looking at the screen.

“Yeah you know it’s weird our Miis didn’t actually get along at first but now they’re attached to the hip, woah it’s almost like us except the hip part and attached part”.

Katsuki looked at him for a second before looking down at the screen. “Huh, it’s pretty accurate I suppose. By the way how was your morning, no hangover right?”.

“Yeah it was alright, maybe I was like that last night because it was my first time?”.

“Who knows, wait I’m gonna go back into the bathroom for a sec”.

“Okay Kacchan”. Izuku just focused back onto the game before Katsuki moved the screen a little bit forward from Izuku’s face.

“Don’t have it so close to your face nerd”.

“Ah okay”.

Katsuki walked to go back into the bathroom before Izuku found himself with the screen back on his face. He barely registered what Katsuki said.

The movie their Miis were watching were over and they were going back to “Kacchan’s” house. Awh cute it seemed like they were gonna have a sleepover. It reminded Izuku of his childhood for a second where he’d have sleepovers with Kacchan most of the time.

Although their their Miis were grown so they were making some dinner and Izuku moved them around so they’d easily fill up the table. Although most of the cooking was done by “Kacchan” whilst “Deku” helped here and there but he ultimately was set on table setting duty.

It was pretty lore accurate that it huffed a laugh out of Izuku.

He watched the Miis finally settle in on sitting at the table. They were eating spaghetti and bolognese with lotus Biscoff flavoured tiramisu placed on the side for dessert.

Izuku thought he was going to drool at the food but then realised it wasn’t real and he pouted.

But that pout quickly turned to shock when a scene script transformed the camera angle and in it “Kacchan” and “Deku” were chattering on about eh food whilst they were sharing food from the same plate until they ended up eating the same piece of spaghetti strand and they were slurping it up but then their lips met.

Oh my gosh.

“HUH?” Izuku yelped as the Nintendo switch slipped out his hands and thrown onto Katsuki’s bed furthest away from him. In that moment Izuku felt blush rise on his cheeks.

And on cue Katsuki walked out the bathroom. “Ugh what’re you screaming for now nerd?”.

But Izuku couldn’t comprehend the words that Katsuki was saying to him because he needed to turn the switch off and save himself!

But before he knew it Katsuki sat on the side closest to the pillow and picked up the Nintendo. “Well spit it out why’d you just…”

Katsuki’s jaw suddenly dropped and he gasped.

Izuku tried reaching out first “uh wait Kacchan it’s not…” but when he saw the screen he himself was stunned.

It was “Kacchan” saying the words “I love you Deku marry me” in that insanely robotic voice that the game used and it was loud, it felt louder in the silence that had been built between them though. And then “Kacchan” got down on one knee and pulled out a ring box!

Izuku and Katsuki looked at each other for a quick second but Katsuki broke eye contact first staring back into the screen.

“Damn nerd better not reject me” Katsuki muttered so quietly it was hardly heard by Izuku but he heard it.

“Kacchan!” Izuku nudged Katsuki’s shoulder trying to get the screen back but Katsuki shrugged him off.

“Shut it nerd”.

So then Izuku and Katsuki just waited in anticipation to see what “Deku” would say.

In the next few second they heard it in the robotic voice: “Yes Kacchan I love you too! I will marry you of course!” Then the Miis started running around in circles.

“Oh shit!” Izuku yelped as he noticed the arrows pointed at each other in the corner of the screen that indicated their relationship was going from in love to married. He didn’t even notice it said they were in love?!

“So this is what you wanted to show me nerd? That we were in love but now married?” Katsuki smirked moving the screen so it dangled behind him whilst being held by his two fingers in a mocking way.

“I didn’t even know we were in love Kacchan!” Izuku whined trying to reach over Katsuki’s lap to retrieve the screen but it was no use.

“Awh so you wouldn’t accept my proposal in real life?”. Katsuki frowned with humour in his tone.

“WHAT?”. Izuku felt his blush intensify.

“You heard me Izuku answer the question”. Katsuki inched his face closer to Izuku now so that there noses were tickling each other.

“Kacchaaan. You’re asking like you know the answer” Izuku sneered.

Katsuki smirked deviously. “Maybe. But it would be nice to hear it from the real Izuku”.

“Fine since you’re begging I’ll marry you Kacchan” Izuku giggled tugging back onto the screen and standing up on the bed triumphantly holding the screen in the air.”I got it—“

Izuku was then abruptly tackled onto the bed and his head hit the pillow.

“You’re going to have to share if we’re married Izuku, otherwise how will we have a long lasting marriage?” Katsuki’s smirk never wavered as he said each word.

“K-Kacchan…”

Katsuki then pulled back. “Well I’ve think we’ve had enough fun with whatever our Miis are, clearly you couldn’t handle me in a real marriage though, what a shame”.

After he said that Katsuki was pulled by the collar of his t-shirt and his lips were pressed against Izuku’s.

It was a sloppy kiss, making it clear that each individual was inexperienced but gosh were they addicted to each other.

They made out for what felt like minutes turning into hours. Izuku biting Katsuki’s lips and begging for entrance which was easily granted and they deepened the kiss as the pace sped up.

“I-Izukuuu”.

Izuku stopped licking into Katsuki’s mouth and switched to open mouth kisses so he could respond.

“So-mm- you think that I can handle..mph! You in a marriage now!”.

“Shut up nerd. Kiss me again” Katsuki spat before pulling Izuku back in by the nape of his neck.

They made out desperately until they couldn’t breathe.

“Geez,just don’t be a deadbeat who plays that game all day and I think we have a deal, I’ll be with ya nerd”. Katsuki cupped Izuku’s face.

“Sounds like you like me”. Izuku giggled.

“I do like you” Katsuki half grinned at Izuku the other half being a glare.

That caused Izuku’s face to turn proper tomato red and he tried to cover his face with both hands but Katsuki wouldn’t let him and he tore his hands away immediately.

“Don’t cover your face from me, stupid shitty nerd”.

Izuku smiled up at Katsuki “I like you too”.

“Heh you do?” Katsuki then wrestled Izuku back onto the bed and they suddenly fought like feral animals.

Yeah their Miis got along a little bit better than this but whatever.

I haven’t actually played Tomadaichi life so I don’t know if it’s accurate so spare me please hehe😮‍💨
