"-Turning to page forty-seven, we see that in relation to the promise he made to Ieyasu, when the battle was definitively lost, Mototada, his family and the three hundred and seventy warriors still remaining committed seppuku, a ritualistic suicide of the samurai class..."

(Y/n) sighed in boredom as she turned the page of her textbook and began to doodle small tornadoes at the bottom corner of it. They were having a History lesson and Midnight kept droning on about some ancient Japanese temple in the West that brought up strong armies or whatnot. (Y/n), however, had long ago stopped paying attention and had resigned to daydreaming.

She rested her cheek on her palm and her eyes fell on Kaminari who sat to her right. He looked like he was about to pass out from pure boredom. He had laid his head on the desk, his eyes slowly drooping with sleep. The girl snickered silently, her eyes going back to her doodles.

She started drawing a rectangle and shaded the inside of it. The corner of her mouth turned up when the drawing brought back memories about a certain time.

(Y/n) stared hard at the ash-blond sitting cross-legged across from her. An arrogant, cocky smirk was plastered on his face as he waited for the girl to make her move. Her scowl deepened at this and she drew in a sharp breath.

It was incredibly silent, with tension running high in the room, the only sounds being that of both students' breathing.

It was late at night, almost midnight and they were currently on Katsuki's bed at the motel. Yet, none of them felt exhausted, not even after four hours of going at it.

The girl drew her lower lip between her teeth, her eyes darting to her fingers and back to the ash-blond's crimson-colored eyes.

She sighed and placed the card down face up on the discard pile. A victorious smile made its way to her lips as she looked back at him. Katsuki looked at her card, his smirk unwavering.

"Your turn," (Y/n) said, sensing her indisputable win crawling very near. She only had one card left and Katsuki had almost five.

She could almost taste victory!

Just his round and she can finally scream Uno!!

Katsuki scoffed while rolling his eyes. His smirk grew into an evil grin, making the girl's smile falter. He then placed two cards down, a wild card four and a draw two, meaning she had to draw sixteen cards, going back to square one.

(Y/n)'s jaw went slack. The single card slipped out of her fingers as she gawked at the two daunting cards. Katsuki continued smirking at her, flaunting his momentary victory at her.

The shock she was experiencing did a full 360 to sheer anger. Her whole form started shaking, her eyebrows twitching as her (e/c) eyes glared holes at the two cards.

I...don't believe it!! Four hours and he still fucking wins!! This is...this is...(Y/n)'s eyes then fell on Katsuki, his smirk stepping on the last single nerve she had left.

"That it!!!" she grabbed the pillow that was on her lap and lunged at Katsuki, who fell back on the bed with a grunt as she straddled him. She was literally seeing red, her blood raging with murderous intent as she began hitting him hard on his face with the pillow.

"You.*hit*.Fucking. *hit* Shit!!! *hit* I *hit* thought *hit* you *hit* were *hit* my *hit* friend!!!! *triple hit*"

Katsuki groaned under her, the hits hitting him square on the face as he struggled to block them off. His own anger was sparked off, making him grab her arms. With an angry growl, he pushed her off him. The force of his push made the girl tumble off the bed to the ground with a shriek.

"Fuck..." Katsuki cursed under his breath as he sat up to look at the girl on the floor.

With a pained expression, she held on to her head while she slowly sat up. "Ow, Katsuki, why did you have to do it so hard?"

The male got off the bed, his eyes softening, full of worry that he had hurt her. He held out his hand for her to take, silently hoping that she wasn't mad at him.

"You fell for it, you fuck!!" (Y/n) yelled, grabbing his outstretched hand while hooking a leg around his waist to pull him down. She twisted herself around so that she'd straddle him once again.

Her hands instantly went to his neck but were grabbed by Katsuki, who tried to put some distance between them and his neck. (Y/n)'s face was contorted in rage as she struggled against his hands.

Katsuki growled at the girl's strength. Sure he was stronger than her but she was still stronger than most girls. He kept moving his head from side to side to avoid her clawing fingers just in case she managed to pry his hands off hers.

"Stay still! I just wanna out your fucking lungs out, you fucking cheat!!" she hissed at him, her rage getting the better of her. Katsuki gathered his strength and overturned her so that he hovered above her. He pinned her wrists down on either side of her head.

"Will you fucking calm down?!" he snapped at her, annoyed by her thrashing movements to escape.

(Y/n) stopped thrashing around and glared at him. "No, I will not calm down!! You cheated!!"

"No, I didn't!! You suck, accept it!!"

"I don't suck!! You suck, you sick fuck!! Now let me go!!!"

"Calm the fuck down!!"

"Fuck you!! I want a rematch!!"

Katsuki stared hard at the girl, both breathing hard from their shouting as their anger simmered down.

The male lifted an eyebrow, a smirk gracing his lips. "Sure 'bout that?"

"Motherfucking positive," the girl deadpanned, her face hardening at the challenge.

This was the tenth time she had requested a rematch and Katsuki wasn't letting her off that easy this time.

"Fine. Loser does winner's laundry," he said, tilting his head to see if she'd back out. In his mind, he had much better deals, one more explicit than the next. But as tempting as they were, he couldn't voice them out and risk freaking her out.

(Y/n) gulped and gritted her teeth.

"Deal."

~~

(Y/n) stared at Katsuki's empty hands in disbelief. He had just won, again.

Katsuki smirked cockily at the girl.

"Now, remember, machine wash with cold water, tumble dry, no bleach and no ironing."

(Y/n) groaned in defeat, her face twisting in agony as she fell back on the bed as loud whines escaped her mouth.

Something hit her head, pulling her out of her daydreaming as she looked at the piece of paper that laid on her desk.

She turned her head to look at the culprit.

What? - She mouthed at him.

Pay attention! - Katsuki mouthed back, pointing at the female pro-hero who was writing on the board.

(Y/n) chuckled silently and flipped him off. Katsuki returned the gesture, which made (Y/n) throw back the piece of paper he had thrown back at him, hitting him square on his forehead.

The ash-blond growled silently, taking the paper and throwing it back at with force, which the girl dodged.

She covered her mouth to stifle her laughs as Katsuki scowled at her.

All through, they were unaware of the piercing, jealous stare pinned on them, especially on the ash-blond.

If looks could kill, then Katsuki would've been dead last month.

***

(Y/n) packed the last of her books into her bag before she rose up from her seat. She turned her head to the back of the class to call for Shouto, only to find his desk empty.

"Huh?" she scratched her head as she looked around the class but finding him nowhere.

She turned to Kaminari, who was standing beside his desk talking to Jirou.

"Kaminari?" she called out to him, the male turning to him. "Have you seen Shouto?"

The male shook his head and shrugged, turning back to Jirou.

(Y/n) sighed and looked around for another classmate to find Uraraka, who was just about to leave with Iida and Izuku.

"Uraraka!"

The said brunette turned to (Y/n). "What is it, (Y/n)?"

"Have you seen Shouto?"

Uraraka briefly exchanged looks with before looking back at (Y/n). "Yeah, I saw him walk out of class with Bakugou."

The (h/c)-haired girl's blood ran cold at her words. "Uh...thanks."

"Sure thing. Bye!" Uraraka waved at her, earning a nod from (Y/n).

Fuck! Knowing those two, they're most likely not meeting up for tea and to discuss politics. The girl inhaled sharply, dropping her bag on her chair as she dashed out of class.

After searching almost every hallway, she finally found them. Luckily, they weren't fighting but the tension around them was enough to suffocate anyone within a mile radius. They were silently glaring at each other, with Katsuki looking like he was about to burst a fuse. Shouto, on the other hand, held a cold glare towards the other male but still looked ready to go off at any moment.

(Y/n) wearily approached them, looking back and forth between them with caution, just in case they decided to fight.

"Uh...guys? What's...going on?" she asked, mostly directing the question to Shouto who was the most likely level headed one at the moment.

"Bakugou here, was just leaving. Weren't you?" Shouto asked, his voice holding a venomous threat behind it if the boy didn't oblige.

Katsuki growled, his fists tightly clenched as he struggled against something. He then clicked his tongue and shoved his hands in his pockets. He passed by Shouto but not without harshly bumping shoulders with him.

(Y/n) looked at the retreating male's back with concern and turned to give Shouto a puzzled look.

"The fuck was that?"

Shouto turned to look at her, his cold facade softening as he gave her a reassuring smile. "Nothing."

(Y/n) narrowed her eyes at him suspiciously. "That ain't look like nothin'."

Shouto sighed and took her hand to lace his fingers with hers. He then brought it up to kiss the back of her hand.

"Don't worry," he said, his heterochromatic eyes falling on the direction Katsuki stomped off to as his voice became slightly sinister. "I was just making sure he knows his place."

10 minutes earlier***

"Fuck you want to talk about, half ass?!"

Shouto sighed and jammed his hands in his pockets. "Calm down. Besides, don't play stupid. You know the reason why I called you out here."

Katsuki's scowl immediately twisted into a cruel smirk. "Lemme guess. She told you, didn't she? How I made her day and night? Is the little pathetic boyfriend jealous?"

Shouto's eyebrows furrowed at his poisonous words, spitting out the word 'boyfriend' like it was venom in his mouth. His composure was chipping off by the second, he had to do this fast.

"You better be careful about what you say or do. Especially around her. I know how you feel about her," Shouto said, trying to even out his voice.

"Haah?! And so what?" Katsuki jeered, his malicious smile on his lips. "So what if I like her? Huh?!! Scared that I'm gonna steal your girl?!"

Shouto growled at him, clenching his jaw. "I'm not scared but I'm here to tell you to stay away from her."

Katsuki smirk fell into a raging scowl. "Who the fuck do you think you are?!! You can't tell me to stay away from her!!"

Shouto maintained his cold stance. "I can't tell her to stop being friends with you so that's why I chose to tell you. Is that so much for your small brain to understand?"

"Why you fucking shit!!" Katsuki began advancing towards Shouto as wisps of smoke began to seep from his palms.

"I wouldn't do that if I were you," Shouto said, remaining unintimidated by Katsuki's threat.

"Huh?" the male stopped, the smoke extinguishing.

"Tell me, if we started fighting and (Y/n) were to come here, what'd you tell her we were fighting for?" Shouto continued, a sinister smile slowly growing on his lips. "Of course you can't tell her that it was because you have feelings for her, so you'd have to come up with something else."

Katsuki's scowl deepened behind the truth to his words as Shouto continued.

"And of course, I'd tell my side of the story. Now, think about it, who would (Y/n) believe, her own boyfriend or the condescending jerk with temper issues?"

A muscle in Katsuki's jaw twitched as he swallowed Shouto's words. Of course (Y/n) would believe Shouto and that would set him back in his progress with the girl.

His whole form shook in anger as he restrained himself from beating up the dual-haired male.

Shouto, satisfied with Katsuki's silence, chose the moment to conclude the 'conversation'.

"Now, with that in mind, let this be the first and the last time I'm telling you this. If you even dare try anything with (Y/n)..."

Katsuki balled his hands into fists, his glare intensifying as Shouto took a menacing step towards him, his eyes burning with promise.

"I will end you."
