NOTES: This is a college/university fic, so Yuji is already a young adult here. A Student!YujixProfessor!Sukuna fic that we all need. Enjoy!

FOM-FOM-FOM-FOM

"A waltz?" Asked Yuji from his seat, waiting for his lover to finish his work for the day. Sukuna was on his desk finishing grading papers he gave last minute. One would think he was cruel for giving such heavy work, but he was teaching them the real world never waited for anything or anyone. Projects came at the drop of the hat and he wanted to make sure his students learned that lesson.

"Yes" he tattooed man didn't bother to look up, "one of the professors is retiring and he enjoys the English history so the university is doing a farewell party. Complete with waltz" he pushed the top of the pen repeatedly with his thumb. So far his students have done well with the work, a couple of mistakes but nothing it would hurt them. Finish grading the paper he was currently grading, he took his glasses off and stretched. Sitting still for so long was not good for him.

He looked at his younger lover and sighed. He could guess why his brat was worried, Yuji knew how to dance, very well in fact. But a waltz is a slow dance and if he knew the retiring professor well, he would want the slow waltz, taking time to enjoy the music and their respective parters.

Yuji prefers upbeat, almost fast beat music so this is something completely different and well out of his comfort zone. History was not really his forte, but he does his best when it comes to Sukuna. The older man has a fascination with Ancient Japan, all the way to the point of wearing a woman's kimono on top of his clothes since they are more comfortable. Still, this would be something new for him to try.

"Are you going?" Yuji quickly looked away when he asked. Seeing Sukuna stare at him was something he is still getting used to, as the older man still looked at him with tenderness in his eyes. He rarely let his emotions show and it was only at the comfort of his home or the seclusion of his office. As badass he made himself show to others, he was a little shy showing his caring side.

"Still thinking about it. I may go since I knew him for a long time and he was bearable" he leaned on his desk and looked at the last few papers he still needed to grade. He gathered his papers and told Yuji to do the same, it was time to head home for the night. Tonight Yuji will stay with him, the school is almost closing up for the semester so most of the young man things' are with Nanami and a few are on his home. They have been together for over a year but they're still taking things slow, especially Sukuna, so they haven't gone to that milestone. He knew he wasn't everyone's type and the tattoos certainty didn't help. (Luckily for him Yaga cares more of his ability to teach rather than looks) Still he hopes Yuji will stay by his side.

Yuji, himself was thinking how they have gone this far ahead. He thought Sukuna would bore of him and cut things off, but instead he keeps him at his side. He takes time to teach him things, show him places Yuji would never think of seeing. Compared to him, Sukuna was more interesting, his body was well muscled, not ripped or bulky. His tattoos make him look dangerous when he's a softie. It warms his heart to know that Sukuna is willingly showing his softer side to him. He sees how the older man feeds the stray cats around his home, makes sure his elderly neighbor has groceries for the week.

Compared to Sukuna, Yuji is plain. He likes modern music and go to clubs with his friends. He keeps fit, but never at the level of Sukuna. The younger man still lives with his guardian when the dorms are closed. He looked plain with the exception of his pink hair and brown undercut. He was unusually strong and freaking fast, but so is Sukuna. Yuji is in university but no carrier path, Sukuna knows what he wants and he is set in life. Sukuna is steady while Yuji is like a storm, no rest or peace. He'll get bored of me and move on, Yuji thought sadly. It's only a matter of time so he should take advantage of it and enjoy the time they would have together.

"Focus on me" he heard Sukuna say. He always say this when he saw his lover in turmoil. It worked on keeping Yuji grounded. Yuji breathed as he looked at Sukuna, focusing on him.

"Thanks" he smiled. Just a matter of time, he repeated. Everyone left him, Sukuna will be no different.

"Wait, you know I never dance a waltz before!" Yuji cried out. Sukuna had just informed him that he would be joining the party at the insistence of Gojo. The bastard heard of the party and wanted everyone to come, "I'll pay for everything" he said, albeit too cherry, but with the heir of the Gojo fortune paying then who was to deny him anything? Not even Sukuna could say no to that.

"I know" the older man put his hands on his hips, "I'll teach you" he walked over to the music player. Fumbling for a bit Sukuna settled for one and walked back to Yuji. "Now the waltz is not just a dance for two" he started, "it's used for strengthen relationships and symmetry between partners" he closed the distance between them. "A lot of organizations would have this as practice as a way to strengthen bonds between partners. A way to sync with each other. Now your left hand holding my right - no, like this - there. Then your right hand on my waist - stop squirming Punk Ass!" Yuji squirmed a bit, Sukuna as seen him dance and a few times they danced together, but this would be the first time they danced like this.

Yuji blushed as his hand was placed. The few times his hand was there was when he was under Sukuna either pulling the older man to go deeper or pushing to go slower, or the times Sukuna was under him as he took the tattooed man. This time was in an open setting, not between the sheets, but standing in front of him learning another lesson.

"Good" the older man praised, "now move your foot with mine, but careful not to - ow! - step on my toes" he winced when Yuji stepped too far. Sukuna rubbed his foot on the opposite calf. Okay, so shoes off for now. Barefoot they continued the lesson, slowly introducing him to the steps, watching in fascination as Yuji learned new steps.

After a couple of songs they stopped for the day as Sukuna kissed his forehead, "well done" he praised again, and Yuji beamed. Sukuna was very patient with him, allowing him to make mistakes and correcting them when needed. He made sure his younger lover was comfortable with his hand positions, knowing the reasons for the red face. Maybe tonight seeing they had a day off tomorrow, that is if he could get Uraume to leave for the night. His assistant needs to get out more.

They continued with the lessons with the next few weeks, Sukuna taking his time to teach multiple songs and their respective dance. He knows Yuji would use these a couple of these steps the next time he went clubbing.

"Focus on me" he lifted Yuji's chin. Yuji was developing the habit of looking at their feet when they danced, and Sukuna was already working of breaking that habit. Yuji nodded and kept his eyes on the older man.

Sukuna's face turned harshly, Yuji's fist landing it's blow perfectly. Yuji moved side to side, not keeping still while his lover quickly recovered from his blow. Sukuna quickly wiped the blood off from the corner of his mouth. Not shocked that the younger man landed a hit on him.

Unlike Sukuna, who knew street fighting from his younger days as a gang member, Yuji was professionally trained in martial arts with a bit of boxing on the side. This time Yuji was teaching him. This was one of the few days where they both had a day off and a bit too much energy to burn off. So they spar with each other and it was the few subjects Yuji would teach Sukuna how to kick is opponent without loosing balance, how to make his body lighter when falling or heavy to land a more powerful blow. Sukuna managed to dodge a fist when he returned his attention to his lover. He was going to be so sore tomorrow and his students will get the wrong idea, but then again they have been working hard so he could let them have their laugh this time.

He lost focus again when Yuji managed to swipe his feet off the mat and he landed on his back with an audible "OOF" Yuji helped him up and fused a bit over him before he let him be and moved a couple steps back. Damn, his love can really take him down. He got to his feet trying to think of ways to pin his brat down. His mind filled with unnecessary thoughts, quickly becoming cloudy.

"Focus on me" Yuji smirked as he got ready to attack again. Feeling his head clear and his thoughts fading away he let his lovers words lure him back to focus.

Getting to his stance he thanked Kami for bringing Yuji to his life.

Storming into his office was not something that occurs often, causing Yuji to jump from his place in the sofa. He finished classes early now that they're almost done, the professors are focusing on studying and grading last minute papers. Sukuna took of his kimono and draped it over his chair, he sat in his chair and sank into it with an long frustrated sigh.

Yuji leaned on the back of the sofa, looking at his lover for a while. He had an idea why Sukuna would come like this.

"They're at it again, aren't they?" He tilted his head. Yaga could turn a blind eye to them, but not when so many voice their displeasure at their relationship.

Sukuna only nodded. For a prestigious school there are sure a bunch of idiots here. "They demanded that I break things off with you" he looked at the ceiling, "saying that I show favoritism" he snorted.

"Of course you do" Yuji laughed, "my classes are right next to yours, and you're buddy buddy with my professors."

The older man glared at his younger lover and rolled his eyes.

"I just told them to look at your grades, if I was indeed showing favoritism then your grades would magically get better" "Hey!" "but they're still the same, even with tutoring." He sneaked a glance at Yuji. Laughing at seeing his pout. Yuji was a good student, but there are subjects he still struggled with, Sukuna tried tutoring him but seeing how they get distracted easily they decided it wasn't a good idea so he recommended someone else to help the university student. "Gojo vouched for me" he admitted, as much as he hated the white haired man he admitted that having the Gojo heir by his side was a good thing. Thought he thought it may be because he is seeing Nanami and had known Yuji since he was adopted by the blond man.

Still he gave credit where credit is due, his brat has been working his ass off and he still has another week of exams to go.

Still the higher-ups tend to stick their noses where they shouldn't and they demanded a meeting to give a so called 'ultimatum'.

Stop the relationship with Itadori Yuji and he'll keep his job, fail to do so he will be immediately fired and black listed.

Before Sukuna could respond, Gojo asked why this was necessary.

"Well to be frank is none of our business if they are in a relationship, and they're both consenting adults. We all know they're not the only ones in a relationship."

"Students have been coming forward of unfair grading and blatant favoritism" one sneered. Looking at Sukuna as if he was lower than dirt itself.

"Well that would be true if Yuji had been taking any of Sukuna's classes or the professors bribe each other" he lifted his glasses, "But seeing how Yuji's classes are nowhere near Sukuna's, or the professors barely interact than the basic 'hello', I say you have no reason to threaten them" this time he showed his eyes, the blues shining as bright as the sky.

The administrators didn't say anything.

"When will you all learn that you cannot control me" Sukuna growled, "for years you have tried and failed to keep me under your thumb. I'm not a Zen'in or the Kamo or even Gojo, so why the interest on me?" The tattooed man cocked his head. When they did not say anything Sukuna glared at them.

"Oh I see," he sneered, "you hate the fact that I am successful, unlike your precious main families, I've come from the gutter and clawed my way up to the top. You hate the fact that I teach the future heirs of Zen'ins and Kamos" he crossed his arms over his chest.

"I earned my right to teach here" he looked at them in the eye "I learned for years on my subject and excelled. If I remember correctly you weren't the only school who was willing to pay a pretty penny." He smirked. That was true, his subject was only specific to a few careers and even then they were scarce. While he taught at the university, he was mostly requested in museums where his knowledge was needed and respected.

"As far as I know I'm giving my lessons correctly. I teach how the main families were before so they can do better for their clans. If you have a problem with that then you can get someone who is not in their pocket. Then again if you do that you will show 'favoritism' to the clan they would be loyal to" With the expection of Gojo, the other two families have a large influence to the public, but he didn't thanks to his Boss. He needed to pay him a visit, now that he was thinking, for old times sake.

"Know your place, foolish puppets" he snarled and left the room, Gojo following closely behind, not letting the old men have a final say.

Gojo whistled as soon as they were out of sight. "Gotta say, I'm impressed. I knew it was a good thing to have you here with us", he placed his hand on Sukuna's shoulder, who promptly shook it off, "Wait, 'till I tell Kento about this! But seriously though, they needed that little reminder. Hopefully they back off now."

"You fucking dumb ass, of course they won't back off. But it will at least it will keep them off for a while" he stopped in the middle of the hallway, not liking what he was about to say but it was needed, "thank you for standing up for me there" he looked outside the window. Besides a select few, hardly anyone defended him.

Gojo blinked.

Did?

Did he -?

Did he hear that right?

The Great Ryoumen Sukuna thanking him?

"Oh no problem at all" Gojo beamed, "after all wer're family" he wrapped his arm around Sukuna's shoulder. Growling he shook the arm off, "first of all, no. You may be married to Yuji's guardian but you are not my family"

" If I remember correctly, you are in a relationship with my son, so we are family. And here I thought we we're having a family moment!" He tried clinging to the older man.

"Get off you overgrown child! And no we weren't, I was just thanking you for helping me out"

Gojo smiled at the older man. As much as the older man wanted to deny it, he already has family through Yuji, even if Gojo Satorou was part of it. So long as they are together Sukuna would be treated as family. They just needed to take their time with it.

"That's so cool for Satorou to defend you!" Yuji was happy his guardian's partner defended him. Sukuna rolled his eyes, but truth be told it felt nice to be defended. He thought Gojo would throw him to the wolves, but their mutual hate made them allies.

Yuji saw his older lover sink back to his thoughts, if he guess right Sukuna was thinking about his past. From what he learned about his lover, Sukuna was an orphan like himself, and ran with a bad crowd as soon as he was able to go out. He only got out because Yaga gave him a chance to change, and the Boss was willing to part with him. The tattoos came from the gang he used to run with, and his physique and knowledge from the gang leader who took him under his wing in hopes of making him the next leader. Still his life was hard and getting out wasn't easy.

He only got out because Boss saw how much he was uninterested to become the next head and to be frank he was a little too lose to reign over the underworld. He thought of Sukuna as his own son so he had no qualms in teaching him everything he knew and providing him more when he learned of his interest in Japan's history. Something Sukuna was more than happy to share since Boss had a fascination with history. Both spent hours in museums and in history books.

The admins were cruel in reminding him. Reminding him of his meager beginnings.

"Hey" he cupped Sukuna's face, forcing him to look into his eyes. The red eyes seemed so sad and far away, Yuji's thumb rubbed across Sukuna's cheek. Sukuna's not that old, just a few years older than Yuji, but today seemed like he lived a thousand lifetimes.

"Focus on me" Yuji whispered, and slowly, so slowly Sukuna focused on him. His vision becoming clear. Sukuna placed his hand on top of Yuji's and smiled.

"There you are" Yuji kissed his lover.

It was the day of the farewell party and to say Yuji was nervous was an understatement. He had been practicing with Sukuna and even with Nobara when she heard about it. She wanted to impress Maki with her skills and Sukuna had been a good teacher with her too, making sure she knew how to lead and follow, with a hand on her waist and on the shoulder. Yuji and Nobara sometimes fooled around too causing Sukuna to either smile at their antics or facepalm at them.

Nonetheless Yuji was nervous and scared that he would embarrass himself, more importantly embarrass Sukuna. He could deal with the outcome, but Sukuna's reputation could be tarnished. Everyone will be at the party and for sure they'll comment about Sukuna's lover not being able to dance a simple song.

But tonight's the night and there is no getting out of there. The school rented a building and made security tight being the main families and the administration being present. So now that Yuji and Sukuna being inside they will stay for politeness sake. Yuji came in a suit while Sukuna came in his white kimono. He may like the professor but he'll be damned if he wear a suit.

Yaga said a few words and allowed the professor to say his final speech before starting their dinner. Gojo really didn't spared any expenses, the food was exquisite and music was beautiful. Once dinner was done, the music began for those who wanted to dance. More and more people were going to the floor and Yuji could see Nobara pulling Maki to the dance floor, Megumi with his cousin Mai, Toge with Yuuta, and Gojo leading Nanami with their arms linked together. He didn't notice his leg was shaking until he felt a slightly larger hand on his knee effectively stopping his leg. Yuji took a deep breath. It's fine, it's fine. He practiced for tonight. He practiced with Sukuna.

"Come" Sukuna, sensing is younger lover's nervousness, gently pulled him from his chair and towards the floor. Facing each other the older man put his hand on Yuji's shoulder. Yuji silently gasped, he thought Sukuna would not take the female role. So this came at a shock for not just him but everyone who was watching. Now eyes were really on them and Yuji was getting more nervous.

"Focus on me" Sukuna smiled at him, gently leading him, going to the beat of the waltz. They practiced this piece before. Yuji immediately calmed down and focused only on his lover, everyone else was just background noise, there but not important to listen.

Seeing his younger lover focus only on him he whispered again, "now you lead".
