Chapter Text
There were several reasons why Itadori Sukuna resented Gojou Satoru.
First of all, Sukuna deemed it to be illegal for a man nearing his thirties such as Gojou-sensei to be that mesmerizing. Sukuna knew he wasn’t the only one who thought so. His teacher looked straight out of Vogue, with brilliant white streak of hair and a freaking pair of aquamarine for eyes. No, Sukuna wasn’t jealous. He was just simply asking why the universe gave his teacher such looks.
Second, Gojou-sensei was surprisingly fit. Gojou-sensei taught history, yet Sukuna had seen his ability in sports. He practically ran 500 m around the field and almost didn’t break a sweat. Taking advantage of his height (190 cm?! What the hell?! Sukuna had shrieked when he found out), he could easily do slam dunks and smashes in both volleyball and badminton. He could lift a 20 kg barbell and still scrolling through the social media on his other hand while whistling.
Again, Sukuna wasn’t jealous. He was just confused.
Third, Gojou-sensei knew no personal space. Sukuna could fish out his phone and call the police anytime he saw his teacher went too close with other students. Not to mention they were alright with it! Sukuna didn’t understand teenagers these days (why that made him sound like a boomer--) Gojou-sensei would tap on their shoulder, ruffle their head, sling his arm around them, and they wouldn’t even guff! They even appreciated it, and it made Sukuna want to puke.
Fourth, the one that irked him the most (because four was bad number, at that too), was Gojou-sensei seemed to take interest in his younger twin.
Yeah, Sukuna wasn’t blind. He knew Gojou-sensei’s eyes lingered so much longer at Yuuji than at other students. Even Fushiguro Megumi, the so-called Gojou-sensei’s son because his father dumped him a long time ago, didn’t receive such advances. It was a fact known throughout the school how Gojou-sensei adored Megumi as if they were one blood, but Sukuna begged to differ.
Should Sukuna make an extension list about Gojou-sensei’s attempts to entice Yuuji? Sukuna could write down many things, actually. Pick-up lines had become an occurrence that lasted for a week. It was truly a torturous week for him. Next up was the hair ruffling. Sukuna was aware of how soft his brother’s hair was, and Gojou-sensei fancied it as much as him, unfortunately. There was also this flirty tone, which Gojou-sensei used it against Yuuji often. Sukuna wanted to gag every time he heard his brother’s name was called out with that sultry voice.
Sukuna could ramble more about those for hours, if he willed to do so.
Fifth (oh look! There’s another one! Fucking great), Yuuji never appeared to be bothered by Gojou-sensei’s behaviors. Sukuna had seen the way Yuuji’s eyes lit up at the sight of their teacher as he entered the class to begin his lesson. Sukuna had heard the way Yuuji’s voice went cheerier as he talked to their teacher. It was absolutely cute, if only it wasn’t directed to their model of a teacher.
One last warning, Sukuna wasn’t jealous.
“Keep telling yourself that. Maybe it’ll become true someday.”
Sukuna threw daggers from his glare to Megumi who sat on his left. The black-haired boy blinked back at Sukuna, silently munching onto his bento.
“What the hell you mean by that?” Sukuna spat. Megumi gave him a blank stare, and Sukuna swore this edgelord was just toying with his thread of patience. For additional note, Sukuna had a very thin and short thread of patience. Students, and even teachers, knew they shouldn’t fuck around with Itadori Sukuna. He didn’t receive golden medal in karate for nothing, after all.
“You’re upset, aren’t you?” Megumi had the audacity to pause his sentence for taking another bite of his tempura, and he did it so casually too! If only Megumi wasn’t a part of Yuuji’s precious friends, Sukuna might have snapped at him since long. “Because Yuuji-kun’s getting closer to Gojou-sensei.”
“No shit, Sherlock. Of course I’m upset. I’m his older twin, for fuck’s sake. Yuuji is too innocent for his own good.” Sukuna rolled his eyes, bringing both heels to rest on his desk. He leaned his back to the chair, hands interlocking on his nape as he heaved a snarl. “You’re the one who lives with Gojou-sensei since… What? 7 years old? You should know best how perverted he actually is.”
Megumi nodded in silence, mouth still full with rice and tempura. After that they didn’t exchange any words, for Sukuna had nothing more to say. They let the busy atmosphere of break time engulfed them. The noisy and livid chatters of their classmates, the rustles of leaves that grew near the window, and the distant voice of other students playing in the school yard. It was nothing near peaceful, yet Sukuna was able to find some serenity in them.
“Suku-nii, Suku-nii! I’m back!!”
Akin to an expectant cat, Sukuna perked up at the jubilant voice.
Itadori Yuuji surged through the class door dramatically with two packs of bread in hand, a smile brighter than the sun was flashed at Sukuna’s direction. In no time Yuuji had reached his older twin’s desk, passing one of the breads to him. “Here! I got the bread you want, nii-chan! You’re in luck! I almost ran out of them, but I manage to snatch it before anyone could!”
“Yes, thank you, and there’s no need to boast about it, brat.” Sukuna resisted the urge to roll his eyes, and he settled for a half-hearted grumble instead. Yuuji plopped down onto his seat on Sukuna’s right, ripping the package open and taking a big bite of his bread. Sukuna could see how hungry he was, judging from how he devoured the poor pastry in mere seconds. His cheeks puffing with bread, his eyes glinting with mirth from the taste, and his lips pulling to the side to form a wide grin. He’s too cute, damnit, Sukuna inhaled sharply.
“Eat it slowly, idiot. You’ll choke if you eat it that fast.” Sukuna leaned over and thumbed away the crumbles that remained on Yuuji’s lips, the action was almost autopilot. He internally awed at the tenderness of his twin’s lips, unconsciously brushing his thumb longer than he intended to before he pulled away.
“Sorry, nii-chan. This just tastes great! You should try it, too!” Yuuji beamed at him, causing Sukuna to ponder what had he done to deserve a ray of sunshine such as Itadori Yuuji. He doubted being the King of Curses counted.
“I will, don’t worry.” And Sukuna couldn’t do anything but relent.
Just somehow, Sukuna could feel Megumi’s unwavering stare boring holes to the back of his head. He gave the boy a sidelong glare, nonverbally telling him to mind his own business. Megumi shrugged, focusing back to his bento.
Oh right, if anyone’s wondering, Sukuna had memories of his past life.
There wasn’t much to say, honestly. Sukuna knew how he died, how he got resurrected into the body that became his twin’s in the next life, and how he died again. It wasn’t a pleasant place to wander, and so Sukuna just let it be. It was odd, most of all, to see most sorcerers his vessel once befriended also became his friends here although begrudgingly. And how their personalities didn’t differ much from last time was also beyond Sukuna’s understanding.
(Sukuna also tried his best to become civil with them, okay)
Did fate give them a second change? Probably, considering how fucked up everything was. Either way, Sukuna was glad.
He was glad he didn’t have to inhabit Yuuji’s mind and soul to claim him this time.
Since their parents had passed away since they were young and their grandfather followed when they enrolled to Jujutsu High (ah, imagine the irony), Sukuna made sure that Yuuji could live well, safe, and most importantly, happy. He learnt the way to gain someone’s trust didn’t have to use ruthless methods all the time. The kind ones worked incredibly well, even Sukuna himself was surprised.
While there weren’t any curses or another dangerous shit that happened here, Yuuji was still the same strong, loyal, and warm-hearted boy Sukuna once knew. Yuuji managed to reel Sukuna’s callous heart in into his circle of kindness, and as a good older twin he always had been, he followed his younger twin.
Because, well… Sukuna loved his twin, no matter how bratty he could be.
As the bell rang once again, it was their cue to continue their study. Sukuna arched an eyebrow as Yuuji hadn’t come back ever since he offered himself to dump their bread packaging to the trash bin outside the class. He could already hear the knocks of Ieiri-sensei’s heels from the hallway, and every student knew how soul-chilling her stare could be when she was angry, or in general.
“Oi, where’s Yuuji-kun?” Kugisaki Nobara, the snarky girl who sat in front of Megumi, piped in. Megumi answered with a dull “Don’t know”, while Sukuna already stood from his chair to look out for his twin. The shrill screech of his chair sent alarms to the whole class, and Sukuna’s eyes narrowed at the noise.
Their classmates’ eyes turned at him, examining each of his movements. Sukuna rarely left his seat unless it was for important matters. He usually shoved it all to his brother, who always accepted his whims with a grin that rivaled the sun itself. Despite known as Jujutsu’s Top Delinquent, Sukuna was way calmer than his vibrant brother. Sukuna made his way to the doors and slid it open rather harshly, blinking as he was face to face with Ieiri-sensei and Yuuji.
“Both Itadoris, come back to your seats at once.” Ieiri-sensei reprimanded with her tedious voice, shuffling over to the teacher’s desk. Sukuna spared a glance to her tall figure, before he shifted it back to his brother.
“I’ll tell you later, nii-chan.” Yuuji smiled gently at him, and Sukuna faltered.
Sukuna scoffed with no bite at all. He better died again and again than admitted that he was soft for his brother. “You better be.”
Ieiri-sensei’s lesson had ended, and maybe Sukuna had to add another number to the list of things he resented from Gojou-sensei.
“He’s asking you to what?!” Sukuna screeched, and their classmates turned their attention away from the Itadori twins on cue. They knew better than to prod. Except for Megumi and Nobara, since those two were always looking out for Yuuji when Sukuna couldn’t. Each of their egos were also as big as Sukuna’s to admit that they cared deeply for Yuuji. Again, just like their past selves.
“It’s just to grade the others’ works, nii-chan!” Yuuji frowned at his sudden outburst. “Why do you sound mad about it?”
Why, pray tell, my dearest twin brother who’s so fucking cute and stupid, Sukuna fumed internally, fingers itching to grip his brother’s sturdy shoulder and shake him. You’re telling me that Gojou-sensei asked you to grade our works together in the teacher’s office after school hours?! For the love of God, couldn’t you see his real intentions?! That teacher is always up to nothing good, damnit!!
“Yuuji, listen up--”
“Shouldn’t you listen to me, though?”
Speak of the devil.
Unlike Sukuna who stayed unfazed, Yuuji jumped out of his skin when Gojou-sensei magically appeared on their side, grinning like a madman as his black shades reflected the glints of afternoon sun from the windows. Sukuna didn’t understand why the school never prohibited him wearing those in class.
“Se- Sensei!” Yuuji squawked, abashment prominent by the flush on his cheeks.
“Now, now, are you two having a sibling fight? Please don’t, alright? The field outside is wider than the class. You could continue it there later.” Gojou-sensei hummed playfully, hand resting on Yuuji’s hair to mess with his strawberry locks. Yuuji’s flush had gone deeper, and Sukuna’s eyebrow twitched as his brother visibly ducked his head, as if asking more from their teacher.
Oh, how Sukuna wished he could use Malevolent Shrine right fucking now.
“Sensei, stop harassing Yuuji-kun.” Nobara drawled out, boredom lacing each of her words. Sukuna felt like shaking her hand in gratitude.
“Of course! My bad!” Gojou-sensei’s hand left Yuuji’s head, but then he sauntered over to Yuuji’s back, holding him close to his chest. The fuck? “It’s hard to hold yourself back when your student is such a cutie~.” He cooed, his grin waning off to a smile that emitted nothing but fondness. Yuuji’s face was akin to a boiling crab, yet Sukuna could see how he slightly leaned to their teacher’s chest.
Welp, there goes Sukuna’s patience.
Sukuna almost lifted his hands, intending to link his fingers together at their tips and bent them as if he was to expand his Domain (he knew nothing would happen, but still). But then Gojou-sensei released Yuuji from his one-sided embrace to stroll back to his desk, grabbing the chalk and pointing it at the students with his trademark maniac grin. “Alright then! All of you, prepare your practice books! We’ll be having a little quiz today!”
At least his classmates’ groans managed to drown Sukuna’s low growl.
On his right, Yuuji was biting down on his bottom lip. He seemed reluctant and wary to reach out for his brother. How he could not, when Sukuna was radiating pure agitation and resentment towards Gojou-sensei? If their teacher sensed it, he didn’t say anything about it. He went forth with his lessons joyfully as always, even if his students’ mood was deterred by Sukuna’s bitter aura.
“Yuuji-kun~! Don’t forget to come to my office after cleaning the class, alright? See you there~.” Gojou-sensei waved his hand with a flirty wink that had several girls squealing. Sukuna swore that teacher must have a fanbase among the students. He stole a glance to his brother who was sweeping the floor, cheeks tinted with pink and warm eyes gleaming as he nodded fast.
Gojou-sensei cackled, and Sukuna wanted nothing but ripped his teacher’s stomach open and used his guts to choke his neck apart. The imagery was wonderful, Sukuna could already hear the echoes of strained screaming and taste the vicious drippings of blood. Gojou Satoru was a bleeding turmoil beneath him, lustrous eyes losing their shine as life crawled away from them.
Sukuna gripped his straining thread of patience before it could really snap when he took ahold of Yuuji’s wrist. “Listen, brat. If you didn’t come back before 4, I’d kill Gojou-sensei myself. You understand?” He warned, voice soft with a dark edge behind it. Yuuji audibly gulped, and he nodded, albeit slower than before.
“Good boy.” Sukuna ruffled Yuuji’s locks, hankering to replace Gojou-sensei’s touch with his own. His chest fluttered as Yuuji leaned into his palm, and Sukuna gained a wave of reassurance seeing the toothy grin Yuuji flashed him.
“Thank you, nii-chan!” Yuuji exclaimed, and Sukuna almost tripped by his own foot as he exited the classroom, afraid he would catch a nosebleed if he stared too long at his brother’s bright face. Since their picket schedule was on different day, one of them usually left the other behind to clean the house or prepare dinner. Today was Tuesday, Yuuji’s turn, so Sukuna went home first.
“Hoi, Sukuna! Over here!” Sukuna lifted his gaze to Nobara and Megumi who waited for him on the school’s front gates. The four of them had this inurement in which they walked home together despite their house’s direction was far from each other’s. It was something that Yuuji initiated, and since he was the glimmer of sunlight who was loved by all, they went along, including Sukuna.
What could he say? He loved his brother too much to reject him.
(Did that sound wrong? Probably not)
“Your mood hasn’t got any better, huh?” Nobara sniggered, slinging her bag to her shoulder as she swatted away a stray leaf her hair picked.
Sukuna huffed. “As if. The thought of leaving that brat alone with Gojou-sensei makes me uneasy. I’d break his bones if he dared to lay a finger on Yuuji without his consent.” Difficult task, knowing how Yuuji accepted each and every single of Gojou-sensei’s far-from-innocent gestures. If only Sukuna could drill his worry into that brat’s head, maybe he would understand how insane their teacher was.
(No matter what life, Gojou Satoru would always be insane, Sukuna concluded)
“You shouldn’t worry much.” Megumi said as he scrolled on his phone and walked absentmindedly. That edgelord could get too engrossed into something that he wouldn’t pay attention to his surroundings. There were times where Nobara had to drag him from a crowded crossroad that hadn’t reached red light yet. If it weren’t for her, Megumi would be admitted to the hospital often.
Sukuna narrowed his eyes at him. “Give me one reason why I shouldn’t worry.”
Finally, Megumi looked away from his phone to stare, blankly again, at Sukuna.
“Because they’re dating, idiot.”
Sukuna froze. What?
“Megumi you’re the idiot one here!!” Nobara yelled and swung her clenched fist down to Megumi’s crown of unruly black strands. Jujutsu’s Number One Edgelord only flinched at her brute strength, unlike that one taciturn upperclassman who immediately fell and bleed from his mouth. “Don’t blurt it out that easily!!”
“… I forgot. Sorry.” Megumi rubbed his head, not sounding apologetic at all. Not even a second passed, two hands grabbed his shoulders and he felt the presence of Satan himself before he was turned to face the said devil.
“Fushiguro Megumi, repeat that one more time, would you?” Megumi gave another flinch as Sukuna squished his shoulder blades under his bent fingers. His crimson eyes were flashing with jeopardize intentions, the smirk on his face had gone impossibly wide and animalistic that the boy below him tensed.
Megumi averted his gaze to the side and croaked out a low “They’re dating”.
“Since when?”
“… Several weeks ago.”
“Thank you so much.” Sukuna uncurled his fingers, and Megumi shifted away some good centimeters from him. Sukuna might be a normal human here, but he had no doubt he still had his forbidding ambience for the other two took a step back and said they would be taking their leave now, leaving Sukuna alone on the pavement as his inescapable hatred was chewing him out alive.
Gojou Satoru better be prepared, because Itadori Sukuna was going to commit a fucking murder this afternoon.
