Work Text:

“Nanamin!”

 

“Nanamin!”

 

“Nanamin!”

 

“Nananananananami—”

“Brat. If you continue doing that I will possess you.”

“You can't even control me right now.”

“You're not even that strong to possess him so shut the f—”

“I don't think, Nanami-sensei is awake.”

“Nananananananananananananananana—”

“That's annoying stop it!”

“He's probably asleep, let's try later.”

 

Nanami opened his eyes in annoyance. He was asleep but the constant banging on his door while calling his name certainly woke him up. He sighed and stood up.

He's on his faculty dormitory that Yaga-san gave him, he uses this if he needs to be at school early or after a mission and it's late at night. It's like those minimalist hotel room with enough commodities to make it like home.

Gojo offered his own home that's near the school but he refused, even if he sleeps there every now and then. He owns an apartment on a high end district by putting in a lot of his money to get it so why would he sleep on someone's house when he has his own home? 

Nanami opened the door just to see in time to Yuuji smacked in the head by Kugisaki and Megumi.

Yuuji noticed him and greeted, “Nanamin!”

“Itadori-kun, may I ask why all of you are up so early banging on my door and waking me up effectively?” His voice rasped. Yuuji looked sheepishly, “We wanted to ask for your help.”

He looked at them, Nobara was looking at her nails while Megumi scrolled on his phone as Yuuji looked at him with puppy eyes.

“Tomorrow is Teacher's Day and we wanted to surprise Gojo-sensei.” If Itadori wasn't a kid, Nanami wouldn't hesitate to slam this door shut. But he collected his patience and said.

“Can we talk this at 9am? This is too early for this shit.” Megumi raised his hand, “We will treat you breakfast, lunch and dinner for the whole day.” Now, Nanami is interested.

With a sigh, “Will you give me time to prepare?” All of their eyes widened in excitement then nodded.

Slowly, he shut the door softly and sighed.

He looked at the comfortable bed and cover. “I shall meet you again, later.” He turned to his bathroom and removed his night clothes to take a shower.

 

It took him at least an hour to get ready, wearing his usual beige suit, blue inner dress shirt and dotted tie before putting his skin care on and fixing his hair then putting on his tinted glasses. With his watch on his wrist and a spritz of his cologne, he walked out of the bathroom to put on his socks and dress shoes, checking his pockets for his phone and wallet, he opened his door and greeted by a sight.

All three was not wearing their uniform but casual clothes, sleeping on the floor. Nobara and Megumi leaning in Yuuji's shoulder.

Nanami coughed to get their attention and they immediately woke up. Nobara looked at Nanami's outfit and grimaced, “You should've gone with casual wear, Nanami-sensei.”

“You need my help, stop worrying about my fashion sense, Kugisaki-kun.”

Yuuji held his arm, “Let's go, Nanamin!”

Nanami sighed, this is gonna be a long day.

 


 

“You want to what?” Nanami stopped cutting the eggs benedict he's eating. They were at this cafe downtown that Nobara found after Nanami drove them using the school's car, much in Ijichi's 'disappointment' to drive them.

The trio had classes today but they opted to skip it since Gojo will just order them around and he's late, as always.

Nanami is a little worried how much influence Gojo has to these kids.

 

“We want to buy Gojo-sensei a gift!” Itadori repeated then ate his third pancake, “Since you know Gojo-sensei, I'm sure you know what he loves.”

“I'm sure Fushiguro-kun here knows more what Gojo likes than me.” Nanami resumed eating as Megumi scoffed.

“All I know is that he loves expensive things and his house is full of useless but pricey things. Probably worth more than the cars the school owns.” Megumi begrudgingly said as he ate his own chicken and waffles.

Nobara gaped from the French toast she's chewing, “Eh? Is Gojo-sensei that rich?” Megumi shrugged.

“The Gojo clan is one of the oldest living Jujutsu clan, they own acres of lands and they probably own part of the Jujutsu school and some business aside if I presume correctly, so your sensei is living with old money that has been inherited to him or is earning through a business we never know.” He took a bite of his eggs benedict.

“Even before, Gojo can have all the things he want. He is that spoiled.” Nanami added and snickered as he remembers the time where Gojo pulled him to a high-end store to buy themselves a white dress shirt that each costs almost his monthly salary back in his old company.

The trio's mood was gloomy and Nanami panicked. Did he say something to upset them?

Yuujo bemoaned, “If Gojo sensei has everything, what new can we give to him?” Megumi sighed, “I told you this wasn't a good idea.” Nobara was quiet, deep in her thoughts.

Nanami groaned inwardly. He knows something that could take Gojo off guard but he doesn't know if it's a great idea.

Putting down his utensils and drank his coffee, he spoke to the solemn trio, “I might have an idea what you would give him but don't tell him I gave you this idea.”

Suddenly, the trio's mood was lifted.

“It's true that your Gojo-sensei has everything,” The trio pouted, “Yet, if I remember correctly, he didn't have that much celebration in any sorts of events. You could say his youth was boring, he didn't even celebrate his birthday until we came along.”

“So, don't pressure yourself on buying him something, it's the thought that counts.”

 


 

After that talk, Nanami thought they would go back but then after a phone search with Megumi as Yuuji and Nobara bickered with each other, they are now in a bakery where it makes customized cakes.

Under Nanami's supervision, he let the kids show what kind of cake they want to give to their sensei. They accepted the design however they don't do rush orders, upon seeing their forlorn faces again, especially Yuuji, they cancelled their order while apologizing as they left the store.

Nanami sighed and got his checkbook underneath his coat and wrote off five digits and gave it to the baker who widens their eyes at the amount. It was at least triple the amount of the price they gave to them, with no other choice, they accepted the check and proceeded the order. The baker told him that they can get the cake tomorrow morning and he thanked them before walking outside.

“Eh? Nanamin, why'd you took so long in the bakery?” Yuuji asked.

“I tried to come up with a resolution but they really won't accept rush orders, I'm sorry Itadori-kun.” He lied, Yuuji sighed, “It's okay, Nanamin. We tried but hey we got another idea!”

They went to a craft store and bought a box, paint and some crafts, paying it with their own money. After which, they went to a digital printing store to print what they made for their sensei.

While waiting, Nanami looked at the cameras available. There were instant Polaroids that young people bought, some film cameras, digital cameras and DSLRs. Megumi was staring to a reusable film camera but shook his head, muttering he doesn't know how to use it.

“Nanamin and Megumi, we're gonna buy some snacks. Is there anything you want in particular?” Yuuji asked as Nobara held his arm to go out.

“Any sweet buns will do.” Nanami said as Megumi shook his head. The duo ran out of the store while Megumi and Nanami stayed.

Megumi was still staring at the cameras before Nanami sighed, “Sir? Can I get three reusable film cameras, one instant Polaroid camera and some films for the cameras.” Megumi was stunted, “Nanami—”

“Let's keep this a secret, shall we?” Nanami smiled timidly as the worker prepared the things Nanami said and checked for any damages.

“Nanami-sensei, it's too much.”

“Nothing is also too much to Gojo's eyes, Megumi-kun.” Nanami gave his black card to the worker, “Besides, this should give you memories to remember. You didn't have that much when you were young, didn't you?” Megumi's blood rushed to his cheeks.

“Take this as an opportunity to create good memories.” Nanami said and gave the bag full of the cameras to Megumi, who's now blushing.

“Now, I can see why Gojo-sensei likes you. Thank you, Nanami-sensei.”

“You're welcome, Megumi-kun.”

Yuuji and Nobara came back after they got the pictures, they didn't question the extra bag Megumi is holding.

As they walked in the shopping mall, they stopped to a branded store and went inside. Nobara lead the boys through the men section and told them that they will share to pay at least one expensive clothing that their teacher would love.

While looking, they suddenly found the perfect clothing. It was a white dress shirt that is embroidered on the chest as well as the back. It was a little expensive but they agreed to pay for it.

As the two boys went to the cashier to pay for it, Nobara was looking at the women section and found a perfume that she's been looking for. Checking the price, she groaned. “I'll wait for my next paycheck on exorcising curse.”

Nanami, who was beside her took the perfume and grabbed Nobara's arm to the counter but before that they walked in the men's perfume and grabbed four different colognes that he himself was looking.

The two boys looked at them and sputtered at the things Nanami brought to the counter.

“Nanami-sensei!” Nobara exclaimed, “I was gonna buy it on my next payday check!”

“I know but you're already making eyes on it and I can't handle anymore second of it— please separate the perfumes and give the women's perfume to this young lady.” The cashier nodded in trance as she accepted his black card. After paying, he left the kids on their own as he waited outside.

On the way to lunch, Nobara poked him.

“Oy, I didn't get to say thank you so thank you, Nanami-sensei. You didn't have to do this.”

“You guys are already making effort on planning a surprise to the most annoying person we all know, my respect to all of you skyrocketed and also paying for my meals, this is the least I could do.” He walked ahead as they entered another cafe to eat lunch.

Lunch was eventful. Gojo called Megumi in the middle of lunch and demanded where they are so he could follow them since they skipped school which to Gojo's 'dismay'. The trio panicked as all the things they bought for Gojo was everywhere.

Nanami just held out the keys for the car as Yuuji, with his speed, ran out to hid the things they bought in the trunk and went back before Gojo waltzed in the cafe.

“My delinquent students, hello!” He leaned to Nanami's cheek and pressed a wet kiss in there, Nanami grimaced.

He sat on the chair next to Nanami and ate at what's left on their plate.

“Imagine my surprise seeing no one was at the classroom! I thought you guys were just late but then hours later you guys never showed up, so I checked your dormitories incase all of you were sick and managed to infect each other and then surprise! You guys weren't there.” Gojo finished as he drank Nanami's sweet tea.

Yuuji and Nobara smiled as they tensed up while Megumi scowled further.

“I'm sad you invited Nanami here but not your precious sensei?” Gojo pretended to act hurt. “Anyways, since all of you are not in school right now and all of you are still underage and technically I am Megumi-chan's legal guardian,”

He leaned back to his chair, “I'm tagging with you all until you come home to your dormitories back in school.”

Next thing Nanami knew is they were kicked out of the cafe for being too loud as the trio complained on their sensei sudden statement. Gojo just smiled at the patrons around until the manager politely asked them to leave but without getting mesmerized by Gojo.

They only had one store to go before they all went home but since Gojo is with them, they can't exactly lie to him. Nanami pulled Yuuji and went to whisper loudly so Gojo could hear.

“Go to some stores and bring Nobara and Megumi with you, I need to talk to Gojo for an hour. Use this check to buy what you want.” Nanami winked at Yuuji giving a check who then pulled Nobara and Megumi to the store they need to go.

Nanami pulled Gojo to the other side of the mall far from their supposed location so Gojo won't see them.

“Oy, Nanami, you naughty man. I didn't know you want me this bad.” They went to a toilet that wasn't visited by many citizens.

He pushed Gojo inside to an empty stall who now smirked.

“Come here.” Gojo huskily said.

 


 

An hour later, they went out of the public toilet with Nanami limping and Gojo smirking, both lips bitten red.

He texted Yuuji to meet them on the parking garage of the car so they won't have to see Nanami limping just to save shame. Gojo offered to drive since Nanami can't move well which led to Nanami smacking him on the side of the head.

The trio entered the car after putting a bag in the trunk. They greeted their sensei's then Gojo started driving the car.

 

The car ride was silent, if not of the kids on their phone typing furiously. Gojo was humming to the sound in the radio while Nanami looked outside.

They stopped at the entrance of the school.

“I need your Nanamin for a while, do you still need him later?” They froze, Megumi answered, “Well, we did compensate on paying Nanami-sensei's dinner but I think another time will do.”

Gojo smiled, “Well, if that's the case let's have dinner altogether, I'll pick you three up at 6:30 and let's eat outside. My treat now.” The trio nodded and went to open the trunk.

Before Gojo could see what's inside, Nanami turned his head and kissed Gojo on the lips. Making out with him as the kids carried the bags inside the school. Nanami stopped as they were out of sight.

“You're clingy today, Nanami. What's gotten in to you?” Gojo hummed and drove the car. Nanami just smiled.

 


 

After dinner, the trio made their surprise in Yuuji's dorm room, while Nanami was staying the night in Gojo's house. 

Both parties stayed up all night.

The next morning, Nanami made breakfast for themselves and left the house, leaving a small note as Gojo slept in. Using the car from yesterday, Nanami dropped by the bakery and waited as they made their finishing touches. He texted the trio to tell him if they're gonna surprise Gojo.

After an hour, Nanami's phone rang. Picking up and greeting the caller, “Hello, Yuuji-kun—”

“Nanamin! We're gonna surprise sensei like today! At this moment! He's coming!” Nanami's eyes widened and ended the call.

He called for the baker who at the same time called for him. Nanami took the cake and held it gently, giving his thanks and went outside as he tried to walk fast to the car.

Thanking above, there was no traffic outside and Nanami made it to the school. Holding the 6x3 cake, he carried it gently to the room where he thinks the first years are. As he walked closer, he could hear the yell of surprise and a laugh.

He stopped and looked down at the cake box he's holding, while leaning at the window still he opens the box revealing a buttercream cake with vintage designs of blue and white, the dedication saying:

“Happy Teacher's Day, Gojo-sensei! From Yuuji, Megumi, Nobara and Nanamin!”

Unknowingly smiling at the dedication, he took out the cake from the box and placed back the top placing the cake carefully and then walked as he showed himself on the doorway.

“Happy Teacher's Day, Gojo.” He drawn out, the trio was shocked at the cake while Gojo let out a “Huh?”.

Nanami entered the classroom, “The students had this cake customized specifically for you.” Giving the cake to Gojo, planting a small kiss near his mouth.

“Nanamin, I thought they didn't accept any rush orders.” Yuuji said with his bottom lip trembling.

Raising his hand and then tousled his hair, Nanami spoke. “They do but the design you all have was beautiful to be thrown out so I made a way— which is a secret.” He quickly added as he saw Yuuji raising his hand to question.

Suddenly, he felt three pairs of hands hugging him. Gojo smiled, taking his phone out and took a picture of the cake with Nanami on the background hugged by the kids.

“Gojo, delete that.”

“No.” Gojo stuck his tongue out playfully as the students said their thanks to Nanami. Removing his blindfold, he arranged his hair accordingly and took out a pair of dark, rectangle sunglasses.

Out of nowhere, Megumi's eyes widened as he ran to the back and took a paper bag, the one Nanami bought for them in the camera store. Like a child showing his acquired candy, Megumi took the Polaroid camera and showed it to Gojo.

Nobara squealed, “We should all get a photo together!” Megumi nodded as he smiled and gave it to Gojo who tousle his hair before raising it up.

Raising the camera up, Gojo announced.

“1, 2, 3, cheese!” A click was heard and they could hear the mechanical printing the photo to the Polaroid.

Excitedly, Megumi took the photo and shook it revealing the most wholesome photo they all have.

On the side of the photo was the cake as Nanami smiled a little while Yuuji, who's hugging Nanami, grinned widely. Nobara made a peace sign beside them and Megumi smiled near Gojo who's also smiling.

Megumi ran back to the paper bag to get the reusable film camera as Nobara took their wrapped box and gave it to Gojo, signalling Yuuji to take a video.

They all sat on the ground, even Nanami who's literally wearing a suit. Giving his thanks, he opened the gift slowly and saw an artfully painted box. Tilting his head, Yuuji cheered excitedly while Nobara clapped her hands, Megumi was snickering beside them while taking a picture on his film camera.

Unboxing the lid showed the beautiful white dress shirt that was decorated with confetti's and a note saying, ‘from yuuji, nobara & megumi’ and a perfume on the side as well with a note saying, ‘- nanamin♡’. Gojo turned to Nanami who blushed facing head on the other way.

Megumi took the photo.

Gojo took the shirt and smiled as he went over the details of the shirt. He put it on his lap as he took the perfume, opening before smelling at the nozzle, smiling. Placing the perfume down, he took out a DIY magazine, the front designed with a plain white background and a small dark sunglasses in the middle like the one he's currently wearing. On the title, it says:

gojo satoru

the most powerful incredible sensei

 

by yuuji, nobara and megumi

 

Opening the book, it showed their first official picture of them four. It was before the special grade mission which they don't want to remember. Gojo's eyes looked down when he noticed what seemed to be like their handwriting.

 

one of my inspiration

yuuji

 

the one that i trust the most

nobara 

 

the white-haired stranger who saved me

megumi

 

Gojo smiled as he flipped the pages seeing words that they wrote or type with photos on it. He read word by word, not missing out every letter and punctuation while smiling.

Everyone held their breathe as Gojo flipped the last page and sighed.

“You know, you're the second people who gave me gifts like these, just pure creativity and not the one where it has diamonds or like cost quite a lot.” Gojo chuckled.

“But this?” He held the magazine up.

“Worth more than all of those things combined. Thank you, Yuuji, Nobara and Megumi.”

Nanami leaned back as they did a group hug. Grunting as Gojo pulled Nanami to join them.

“You, too. I didn't expect the cake and perfume. Thank you, Kento.” Nanami just awkwardly smile.

Gojo grinned and tightened the hug, which led to complaints. “Ahh! I just love you all so so so so so so so so so so so so so so so so so much!”

Since it's a teachers celebration, after the morning ‘class’, they went to a sushi restaurant that Gojo loves bringing the cake they had custom designed. It was moist and a little bit too sweet but Gojo loves it, eating almost half of the cake but the students and Nanami just let him and watched him eat happily.

At the end of the day, Gojo was happy. He finally found people who considers him as who he is.

 

 

If the magazine was decorated on the living room of his house near the accent wall with a glass case and a gold plaque, only Nanami is the sole witness of it as he cried out in pleasure.
