Kirishima:

The bell had just rung, signaling for everyone to pack up, and get out of here for the weekends. As I packed up all my books, I saw that kaminari wasn't as happy as this morning. He was slumping over his desk looking pale as a ghost.
"*sigh*..."
"Hey, um... What's wrong kaminari?" He was looking more down that usual, was he sick?
"Are you sick? You're looking kinda pale right now" he sighed again
"Dude, what's wrong?" He looked up,
"Kirishima-kun..."
"What? Are you okay?" He shook his head,
"You won't believe this but..." I blinked, getting closer,
"What?"
"I..."
"You what?!"
"I... I'm..." his fists balled,
"Kaminari?-" he stood up, his chair scraping the floor, hands on my shoulders now.
"I'm still single!!! Can you believe that?!"
"What... eh??"
"Wahhhhhh!" I looked over my shoulder,
"Mineta?!" His yellow nosed snot smeared on my bag, and I swallowed, 'I am totally bleaching that when I get home- wait hang on! When did he get here?!'
"Me too!!"
"What the heck?!" I let them both go, seeing as they both deflate to the ground in a little man to man "I'm still single" hug.
"G-guys, calm down" it slowly gets worse, 'thank god no body is here to see this'
"L-listen, i-I'm still single too"
"Waaaahhhhh!!"
"A-waaaahhhhhhhhhhh!"
"*sweat drop* guys-"
"Wahhh!! I-it's okay kirishima!! W-we know that feeling!!- guuuuhhh!!" 'This is not manly-'
"Oi! M-Mineta! G-get off!!"
"Aaaaaahhhhhh!!" 'What's with these guys and girls?!'
"This is gonna take a while"

(A while later):

After finally getting them to calm down, I managed to get them to exit the classroom to go home.
"Thank you kirishima-kun" I smile,
"No problem, that's what friends are for kaminari" I looked over at Mineta, and I couldn't help but see the that he was still down, I couldn't exactly think of anything to say to him cause, well, you know him. Girls are always on his mind and if I were to say something about them now, I might as well be breaking another dam... well two.
We headed for our lockers, locking up our school shoes and things we didn't need for the weekend and left.
After heading outside towards the gates, I caught a glimpse of something ashy yellow and stopped.
"Bakugou?" Kaminari turned,
"Bakugou?"
"Hm, I wonder what he's still doing here for, why don't we go say hi?" They shrug, trailing behind me.
"Bakugou!!" Kaminari raced ahead, leaving me and mineta in the dust. 'One second he's down and now he's as hyper a 3 year old?'
-I stopped and turned,
"Mineta? Was is it?" He started shaking violently,
"I-I-I..." his voice was shaky, fear clouded in his eyes, 'is he?...' I slump down to his height and pat his shoulders,
"Um... Are you scared of bakugou?" He nods,
"There's no need to be scared of him" I say, but I don't think it helped,
"Um... well, bakugou can be a little scary sometimes but he's really a good guy, honest"
"You... you sure?"
"Heck yah! He's one of my best friends! He's really cool, and strong. And he doesn't mean what he says most of the times, so you don't have to worry" 'mm... does he mean it?'
"Besides, bakugou couldn't hurt a fly!" 'Okay maybe that's not true either'
"Well... I... no"
"Why not? Why don't you give him a chance? He's friendlier up close, and he might help you find a girl too!" 'Okay I need to stop before I get myself killed'
"Um... I... well... I don't know"
"Hm?"
"I don't know, but" he looked up, "the way you just described him..."
"*sweat drop* Yah? What about him?" 'Did I say something?'
He stick his chin between his fingers,
"Wait a second..." he snapped,
"You don't meant that do you?"
"Huh? Mean what?" His eyes get wide, 'should I just go?'
"*sweat drop* mineta?-"
"Are you trying to say he has a girlfriend?!" 'Eh?!'
"What the what?!" 'Where did that come from?!'
"This can't be cant be true! Him of all people!"
"Hold up! That is not!-"
"Bakugou!!" He ran past, 'Oh shit!' I chased after him, 'is he trying to get himself killed?!'
"Mineta!! Wait!" 'Why does everything he say have to do with girls anyway?!'
"Bakugou!-Mm!! Mm?!" I finally caught up with mineta but it looked as if Kaminari had already stopped him.
"Guys? What are you guys doing?-"
"Shh!" I didn't exactly know what was happening well, until I saw it for myself.
"B-bakugou-san..."

Katsuki:

I can't believe this,
"B-bakugou-san"
"What is it?" I grumbled,
"I-I... I've l-liked you for a v-very l-long time!-" A confession?
"Pl-please go out with me!" She bowed after her little speech, and waited.
"Sorry, But I already have a girlfriend"
"*GASP!!*"
"What the?!-" I turn, "What the hell?! What are your three weird hairs doing here?!" Having jaws hit the ground, i could almost feel myself popping a vein until my name was called again.
"Huh??" It was the girl,
"Thank you for being honest..." she turned, "If you ever change your mind, you can always call me" I irk
'What the hell is with these birches?!'
"..."
"Bakugou! You should have went for her! She was pretty cute!"
"Mm Mm, but wow bakugou, never knew you were one to get confession to"
"Guess someone's getting a lot of the girls attention... *sniff* a-wahhhhhh!"
"Oi! Your getting me wet!-"
"Loyalty is a man's best friend bakugou, I'm proud of you, never knew you were this manly"
"Wahhhhhh!!" No matter how much I wanted to punch eel and red head in face right now, I contained it-
"You have a girlfriend?!"
"Unlike you grape head! Now fuck off!-" I yell,
"Now now bakugou, that's no way to talk-"
"Shut up hedgehog!! Now go away!- hang on! Why the hell are you guys even following me?!" They shrugged,
"What's that supposed to mean you pieces of shit?!" I could see mineta somewhat close to peeing his pants,
"We were just-"
"Katsuki?"
"Huh??"

U:

"Katsuki?"
"Huh??" He turned, steam pouring from every inch of his face,
"*sweat drop* Um... d-did something happen?"
"What took you so long?!" You winced,
"Gomen, Aizawa sensei wanted me to lock up the doors for him since he had to run to a meeting" you say,
"Tsk-"
"*jaws clunk!*" both of your heads turn back,
"(Y/n)?!"
"Y-y-y-you're b-b-bakugou's g-g-g-g-girlfriend?!?!?"
You blush,
"Ehe... Hey guys, what are you guys still doing here?" They blush,
"W-Well~"
"Oi! Don't talk to those dunce heads! There contagious!" Katsuki snarls at them, his hands sweating up a storm,
"K-katsuki?-"
"I'll kill them if they dare touch you!!" He stands in front of you protectively and aims his fingers at them
"Wh-what you are doing?!"
"*whimpers*" they sink to the ground, sobering at your feet,
"(Y/n)chan~"
"Oi! Don't fucking touch her!!"
"Katsuki?..."
"Grrrr!! Mine!!"
"*sweat drop* D-did something happen?" He growls, glaring at three trouble makers before grabbing your bag, and swings it over his shoulders. 'Such a gentlemen...'
"Tsk, lets go, I'm hungry"
"S-sorry I came so late" he shrugged, pulling at your hand, fingers intertwining,
"I guess i should bring you a snack next time" He pursed his lips,
"Whatever" he pulls you along, still pointing daggers at the three males before turning around to lead you out the gate.
"Bye guys! Have a good weekend!-"
"I told you not to talk to them! There contagious!" He glares back at them,
"*giggle giggle*"
"What's so funny??"
"Your cute that's what~"
"Huh?! Where the hell did that come?!"

Kirishima:

Our jaws were still glued to the floor, especially mineta's.
Kaminari had lost his color again, mineta's pants were wet and I wanted to go home.
"B..."
"Bakugou..." 'he has a girlfriend?!'
"How..." we stood there for a few extra minutes, still trying to process what had just happened and if what we saw was real I guess, before actually peeling our jaws off the cement.
"How in the hell does bakugou have a girlfriend?! A-wuhhhhhhhhhhhhhh!!!"
"You were right kirishma-kun"
"H-huh?! I didn't-"
"He does have a girlfriend!!"
"Wahhhhhhh!! I'm gonna be single forever!!"
"G-guys!!"
"Me too!!"
"Waaaaaahhhhhhhh!"
"Waaaaaahhhhhhhh!"
"Oi!!"

(Katsuki's House/ your POV):

Pulling on one of Katsuki's old pj shirts he's given you, you ran out the bathroom pantless towards his room.
"Katsuki!"
"Hm? Come here" his eyes never left his phone,
"What are you doing?" You say besides him, your butt ached on the floor but you didn't care,
"This game" he growled,
"Hm? You haven't passed the level?-"
"Fuck!"
"~*YOU LOSE!*~"
"Well that's new"
"Shut it! New boss"
"Mm~" he threw his phone onto his counter and leaned against you,
"It's okay, you don't have to win at everything~"
"I'll win"
"I know you will baka, you always do"
"Mm" his head swayed,
"Katsuki?" He growled, pulling you closer and started shifting you a top his lap.
"Katsuki?" His weight shifted onto your shoulder, his chest to your back, arms wrapped protectively around your waist,
"You look beautiful without pants" you purse your lips, leaning your back on his front, arms crossed
"Pervert"
"But you love me"
"Mm~" you kiss his cheek, "baka"
"Hmph"
"Your pants can't fit me that all"
"You mean you can't fit my pants"
"It's not my fault you have a big butt!"
"Huh?! Who has a big butt?!" He pinched your bottom,
"Ah! K-Katsuki!!" He smirked, pulling you to his chest again, this time, your chest leaned against his.
"*hums*"
"What are you humming about?"
"Well... Do you think they found out?"
"Huh?"
"Mineta, kaminari and kirishima"
"Well duh, but it doesn't matter, your mine, and I won't let anyone touch you" he squeezes your waist a little tighter,
"They seemed a bit shocked, and I wonder why?~"
"Shut it!"
"But still~ I can't believe they haven't noticed till now, Monday's gonna be a little crazy huh?"
"Tsk, I'll kill them all, fucking annoying pieces of shit"
"*giggle*" he drags you onto the bed, arms still locked around your waist,
"Katsuki?"
"Hm? What?" You touch his hair,
"I love you okay?"
"I love you too, that's why I'll kill deku if he touches you"
"*hums again* It's funny how you just bring up his name"
"It's not"
"*giggle*"
"Hm? Your phones ringing"
"Heh?"
"It might be your (parent)"
"But I already told my (parent) I was gonna stay with you tonight" He quirked an eye brow, still eyeing your butt as you went to get it,
"Who is it?" You pick it off from the table,
"I don't know, it says unknown" he grabs it, sliding his fingers on the call button, sitting back on the mattress with you,
"Who is this?-"
"(Y/n)chan!! We finally get to be alone! I've been waiting to hear your sweet voice!! My sweet darling! We meet again! Why don't you ditch bakugou and come with me! I've been waiting a long time for this not that I finally got your number!-"
"Yes yes!! It was a lot of work but I can finally love you! I'll give you so much more pleasure than bakugou ever will!! So?! What do you say?! Will you play with me?!" Shivers tan down your spine, an arm clinging to Katsuki's,
"No! With me!"
"(Y/n)chan!!"
"..."
"..."
"Eh? (Y/n)chan?"
"You there?-" Your screen cracks,
"Ka-"
"Who in the fuck?! Are you?! What do you want with (y/n)?! You got some balls calling her you fucking stalkers!! And what do you mean you'll giver her more pleasure than me?! Huh?! Who the hell do you think you are?! The hell! I'll burn both of you to a crisp! Fucking answer me!! Oi?! Hello?! I know you can hear me! I'll fucking kill your asses!! Answer me damn it!! Hey!"
"*sweat drop* K-Katsuki...?" He snarls, nearly crushing you phone, before going back to a defensive stand off again,
"Who in the hell are you?! Answer me you prick!-" You take the phone from his hands, not wanting to hear much of his screaming anymore. You take a deep breath in and hold his hand,
"U-um... H-hello? Th-this is (y/n), m-may I ask who your are?" He shifts you onto his lap,
"..." silence...
"Put it on speaker, I wanna know who these lunatics are" you do as he asks and put it on speaker, scared yourself, you cling to him,
"Uh... h-hello?" Another long silence...
"(Y-y/n)chan?"
"Yes? Y-Yes, I-I'm here" another long pause
"Was... um... th-that b-bakugou w-with you?" You look at him, the glare still in his eyes,
"Y-yes"
"I see..."
"A-Ano! C-can I ask who you are?..." his blood boils again, and you kiss his cheek to calm him down,
"Shh" your fingers lock with his while you both wait another deathly silence,
"I-Is this on s-speaker?..." you wince, not wanting to lie to this person but you knew if you didn't lie, you wouldn't be able to find out who this stalker is and he could possibly hurt you without Katsuki around. And mostly it was because Katsuki was squeezing your thigh,
"No" it almost come out in a whimper,
"Promise?" You nod,
"Yes"
"Okay... I t-trust you..." Katsuki hold back flames, wanting to burn the phone on instinct but holds back,
"It's g-grape fruit"
"Mineta?!"
"And eel h-head"
"Oi! Don't rat me out too!!"
"Kaminari?!-" Katsuki snatches the phone from you, turned off speaker and walked out, steam emanated through his ears and nose in a scary matter.
"*slam!*"
"... Kat... suki?..."

(1 hour later):

It was dark, and you were still up, wondering where Katsuki could have possibly wandered off too, but of course, you were slightly worried about mineta and kaminari. Feeling as guilty as her for lying.
"He better not be doing what I might think he's doing" you yawn, your sleep catching up to you. Well, more like guilt and boredom.
You haven't been doing much, much as in laying on the mattress staring at the ceiling and tried to call your phone using Katsuki's but no sweat, he didn't answer...
"All is the days, it just had to be a weekend... well it would be worse if it were a school day" you yawned again,
"7:51..." 'What's he's doing?' You watch as the clocks slowly ticks off.
You didn't like to be by yourself, you were scared, even though you knew Katsuki's house was one of the safest, you just couldn't help but shiver, knowing anything could possibly pop out from anywhere at anytime and kill any second.
You played with his phone to pass time, listening to music from time to time but nothing

7:54
Katsuki/ (you on Katsuki's voice, so we're gonna use his name for you): are you back yet? It's getting deathly quiet and I'm a little scared... you know I don't like it when I'm by myself

7:55
You/ (him on your phone): Yah, I'm heading back, you want a snack?

7:55
Katsuki: yah!! (F/s) Please!!

7:55
You: alright idiot, I'll be home in a bit, just listen to music or play a game or something to keep your mind off of things.

7:56
Katsuki: Okay! I love you!! Please be home soon!

7:56
You: I love you too, and alright

You smiled,
"He's safe..." Your eyes closed, finally knowing he was good.
"Baka..."

Later (Katsuki):

"Oi! (Y/n)! I'm back!" I slammed the door behind me, swiftly locking it, and through off me shoes.
"(Y/n)?"
"..."
"Oi! (Y/n)!"
"..." my heart raced, 'what the fucking hell?!' I raced up stairs-
"(Y/ n)?!" -slamming the doors open, I saw her laying ever so peacefully on my bed and I walked over to her,
"Fuck you scared me..." her legs were a tangled mess with the covers, the shirt I gave her was also a mess on her,
"Tsk, clumsy girl" I dropped the grocery bag on the counter and charged her phone.
Flicking off the lamp, I find no use for the ceiling light and turn them off, a whimper escaping her lips, and I smirk.
"Jeez (y/n), how did you get in this mess?" I quietly crawled across the mattress to her, and picked her up.
"Ka...?"
"Hm?" I untangled her from the covers, pulling down her shirt and placed her down on the mattress again, laying down besides her as well,
"Baka" I pushed her bangs aside,
"Ka..." I sigh,
"Yah? I'm back" her eyes popped open,
"Open your eyes too quickly and you might miss my handsomeness" she scoffed,
"What took so long?"
"Business"
"On a weekend?"
"Mm~"
"What did you do... to them?" He glared,
"They got what they were asking for, did they honestly think that could actually pull this off without me knowing?!"

U:

"*sigh* hai hai, they got what they deserve but hopefully you didn't kill them"
"I killed grape head"
"What?!" You jumped, smacking his arm,
"I was kidding"
"Baka!" He shrugged, his eyes began to droop,
"Hm? What's wrong?" He pulled you under him,
"Sleepy, now that there taken care of, I can finally have you to myself"
"*giggle*"
"What?" You cup his cheeks,
"Baka, you always have me to yourself~" he smirks,
"True true, and it's gonna stay that way" you blush,
"Katsuki, What are you?- Kyaahhh!! K-katsuki!! N-no pervert!! D-don't!"
"Shhh~"
"Nn! N-no! A-wuh!"

Morning:

"Huh?? How in the hell?!- Oi! (Y/n) did you beat this level?!" You stir,
"Kastuki... *groans!* why are you up so early?-" he pulled you to his chest, desperate for an answer,
"Answer me! Did you do this?!"
"Hm? *yawn*" you struggled to get up,
"What are taking about?..." Your rub your sore tired eyes and lean up,
"The game!"
"Hm?" You blinked, the iPhone light blinded your eyes for a sec,
"Oh... that... I was bored yesterday, I'm sorry if I-"
"I don't care about that. I wanna how" you shrug
"I just did something"
"But how?!" You smile,
"I don't know, it seemed easy"
"Easy?! I've been stuck on this level for 6 damn weeks!!" He grumbled,
"Mm" you fell back on the mattress, arms wrapped around his hips,
"How in hell did you do this?!" You smirk, pulling up the covers,
"I'm guessing I'm better than you?"
"You are not! Just cause your my girlfriend doesn't mean this isn't war!! I'll totally beat this level faster than you!"
"Does everything have to be competition for you?" He growled, arms still caged around you,
"How hell did you get past the boss?!" You yawn again,
"It's a secret baka~"
