When crossdressing for a day gets you a boyfriend

Summary:

Wei Wuxian had searched. He had searched amongst the 3000 rules of the Gusu Lan School, being careful not to miss one, and he was sure of it. Nothing said he couldn't wear a skirt.

Now, maybe you'll ask why he would do that ? I mean, it's Wei Wuxian, so it's a pretty good enough reason. But. It actually had a purpose. And It was driving the righteous and all-too-stiff Lan Wangji insane.

Notes:

Hi ! First MDZS fanfic i write, a fellow fan suggested that Wei Wuxian should wear female uniform to drive Lan Wangji crazy, so here is my version, hope you enjoy !!!

Plz don't look at the mistakes, english is not my native language :)

Work Text:

Wei Wuxian had search. He had search amongst the 3000 rules of the Gusu Lan School, being careful not to miss one, and he was sure of it. Nothing said he couldn't wear a skirt.

Now, maybe you'll ask why he would do that ? I mean, it's Wei Wuxian, so it's a pretty good enough reason. But. It actually had a purpose. And It was driving the righteous and all-too-stiff Lan Wangji insane.

Wei Wuxian had seen the way the nephew of the Headmaster Lan looked at him. Clearly, he hated him, and always seemed to be hot on his heels, ready to sanction him for every misconduct he had. It was Nie Huaisang, his best friend, who had suggested the idea. Him, Nie Huaisang and Jiang Cheng were sitting on a bench, absorbing the shy rays of the sun darting through the clouds, when Wei Wuxian had, again, started to complain about Lan Wangji.

"He made me copy the rules three times !! I couldn't go to the dorms before 1 am, that's downright cruel ! Plus he made me break another rule by staying out of my dorm after 9 pm !!!" whined the man, playing with his long hair, pouting. Jiang Cheng, who had his hands crossed behind his head and said head tilted backward, eyes closed, gruntled softly, tired of his brother's antics.

"You literally drank alcohol in front of him and even offered him some. That is more rule breaking than him making you write a few lines. Plus, he's the head disciplinarian for the high school students, what did you expect ?"

" A FEW LINES ?!" shrieked the older, a deep scold plastered on his face. Nie Huaisang just waved lazily his fan, smiling and enjoying the show. "I made over fifty pages !!!!!"

"No shouting." Mumbled his brother and Wei Wuxian jumped on him, which made Jiang Cheng yell at him, chasing him. Once he managed to headlock his big brother, the two came back and Nie Huaisang smirked.

"You know, I'm sure you will find something that is outrageous but not forbidden. I believe in you A-Xian." He told his friend and let his gaze wanders across the yard, thoughtful. Wei Wuxian sighed and plopped next to him, back slouched forward, elbows on his knees and chin in his hands, looking pitiful.

"I just don't know which one…"

A gasp from his friend made him turn his head, and he watched as Nie Huaisang beamed at him.

"I'm sure there is no rules about crossdressing."

Jiang Cheng let out a loud groan, attracting a few glances from other students, but Nie Huaisang and Wei Wuxian were already planning how to do it.

"Wait, we have to make sure it's not in the rules first. I'll go check them, try to grab some makeup and a uniform during this time. Maybe Mianmian, or A-Qing !"

"Nah, she went home because A-Ning was sick and wouldn't stop puking."

"Shijie ?"

"College part of the school, so not the same uniform, idiot. You saw her uniform last time two days ago, are you stupid ?" added Jiang Cheng. He had groaned, but in the end, never said that they should stop. And Wei Wuxian knew his didi, and he knew that deep down, the boy was already planning how to film the whole scene at the best angle.

"Try Mianmian then ! I'll join you back in the dorms once I'm sure it's not in the rules !" Wei Wuxian ran – sorry, speedwalked very quickly – toward the library.

And here he was, reading through the rules, a bright grin on his face as he came back in his dorm shared with his brother and his best friend after more than an hour. He opened the door without announcing himself and a shout, followed by a BANG and by another shout and insults came in and Wei Wuxian gaped at the sight in front of him.

"A-Cheng ?! Xichen-ge ?!?" he screeched, absolutely not ready to see Lan Wangji's older brother pin down his own little brother on the mattress, literally eating his face. Jiang Cheng swore like there was no tomorrow and massaged his head, having apparently bonked it against the bottom of the bunk bed.

"Wei Wuxian… uhm… hi ?" tried the Lan, cheeks flushed and lips swollen – Wei Wuxian felt like he was about to faint – "We… uh."

"Wei Wuxian !!!! For the love of God can't you knock ?!"

"Hey, it's my room too ! Why should I knock ?!" The two brothers were at it again, bickering at each other, and Lan Xichen got up, putting his disheveled hair back in order and tying back correctly his tie, that had been pulled out by an eager Jiang Cheng as he had kissed him.

"I'll go. A-Cheng, see you later ?"

"Yeah, see you later."

"Love you !" chirped the Lan, a big smile on his face. The Jiang boy blushed furiously and mumbled a 'love you too' quickly, making his brother cackles at the behavior.

"So, you're making out with Lan Xichen and did not even tell me ?! Didi !"

"Who you're calling Didi, asshole !" Jiang Cheng was very much not credible, as his blush reddened and the two started to hit each other with their pillows. Just at that moment, Nie Huaisang came in, a big grin on his face.

"A-Cheng, was that Lan Xichen I saw going out of here ? Oh." He stopped, seeing Wei Wuxian, and cocked an eyebrow. The one with the red ribbon in his hair gaped and immediately started to fake cry.

"You knew too ?!"

"Aye, sorry A-Xian. So, is it forbidden ?"

Immediately stopping his act, Wei Wuxian grinned and shook his head.

"Nice ! Well, I don't have the uniform, Mianmian refused to let me borrow one. At least she handed me her makeup kit, but we have to give it back tomorrow before noon." Nie Huaisang looked as sad as Wei Wuxian, but the latest gasped and quickly grabbed his phone before storming out of the dorm, ignoring the shouts of his friends. He ran down the stairs, jumping the steps four by four, nearly breaking his ankles.

"XICHEN-GE !" he yelled in the common area of their dorms, startling the student out of his wits. Even though he was three good inches (10 cm) taller than Wei Wuxian and three years older, he looked frightened, probably thinking that the young man would beat him up for going out with his precious didi. Wei Wuxian stopped right beside him and wheezed a bit, trying to catch his breath. He then jolted up and grabbed the Lan's arm until they were far away from prying ears. "I have a deal."

"… Ok ?" tried carefully the older one, not sure if it was a good thing or not.

"I'll let you date A-Cheng, hell, I'll give you pictures of him when he was a baby, IF you manage to hand me a girl's uniform. High-school one, my size. Deal ?"

Lan Xichen gaped at him, proper manners long forgotten, before hesitating.

"It's not against the rules and you know it. Plus. I have baby A-Cheng in grape onesie. Also baby A-Cheng crying because he saw a puppy and wanted to adopt it. Also I have bare torso A-Cheng pics from last month after that one party where he got drunk out of his mind and start-…" Lan Xichen slapped his hands on Wei Wuxian's lips, a deep red plastered on his cheeks.

"Ok. Ok, deal. I'll let the uniform by your dorm in a couple of hours."

"Once I have it, I'll send you the pics, I have your number. I'll give you the grape onesie one right now, as an insurance." He actually sent it and when Lan Xichen opened the message, he squealed without being able to control himself and Wei Wuxian grinned, pinky out. Lan Xichen grabbed it with his own and they nodded seriously at each other.

"Thank you."

"Why, Xichen-ge, I'm the one who should thank you ! Also. Do you happen to have Lan Zhan's schedule ?"

"I'll send it once I'm back in my room."

They quickly parted, looking right and left like if they had made an illegal deal, and Wei Wuxian grinned at his friends once back in the dorm, just telling them he'd have the uniform in a few hours.

"Alright alright, let's go do our homework, that old Lan Qiren will punish me again if he sees I didn't do it !" He took his bag and grabbed his brother's and friend's ones, forcing them to follow him. They studied for three hours or so, and went back in the cafeteria of the dormitories, tired and minds full of whatever they studied. Nie Huaisang was barely walking, eyes closed and guided by Jiang Cheng pulling at his wrists while Wei Wuxian was holding the three backpacks.

"A-Xiaaan… I'm tired, I can't walk anymore…"

"The uniform is here !"

Immediately, Nie Huaisang shoved Jiang Cheng into Wei Wuxian's arms and touched the fabric, impressed.

"A-Xian, I need the name of your source !"

"Secret ! Ah, wait, gotta pay them." He grabbed his phone and hid himself from the two others trying to pry at it. He sent the pictures – a lot of them, probably around thirty – to Lan Xichen and then put the phone down. They had to plan how he'd show his crossdressing skills to Lan Wangji.

"Ok, so now, how do you plan to do it ?" asked Jiang Cheng, fully awake. "I've got the camera mom gave me last year, and I plan on recording this one."

"Alright, so I was thinking about fully crossdressing, so I can look like a girl, and totally foul everyone."

"Do you know how to do makeup though ?" asked Nie Huaisang. Wei Wuxian and Jiang Cheng looked at the third like if he was an alien and they sighed deeply.

"Oh wait ! Jiejie !" said Jiang Cheng. He called his sister and told her to come over. After 10 minutes or so, the buildings of the girls dormitories being not that far away, she softly knocked and beamed at her baby brothers and their friend.

"How are you ? Cheng-Cheng, you seemed frantic, something happened ?" she looked worried but her brothers looked at each other before turning at her, pleading eyes on.

"Shijie, can you put makeup on my face tomorrow morning before class start ? I… lost a bet with A-Sang, so I have to cross-dress for a day. " His big pleading eyes made her coos but she held her finger on her chin, thoughtful.

"Alright. But you have to be nice to A-Xuan for three weeks."

The two groaned and sighed, fidgeting like babies but refusing to say yes. Wei Wuxian landed his eyes on the uniform and sighed, closing his eyes before nodding reluctantly. Jiang Cheng gasped at his brother but still refused.

"Cheng-Cheng ?"

"I… Two weeks for me !"

"Okay. But you better behave or else, no soup for a month." They shouted at her and she left without saying more, her brothers feeling betrayed. Now they had to not bully her boyfriend. Nie Huaisang giggled and then ushered them back on the bed.

"So. You plan on being a girl all day ?"

"Yep. I'll try to avoid Lan Zhan as much as possible and once I'll join him for those god forsaken rules I have to copy, I'll just pretend I'm me, and see how he reacts."

"How will I record it then ?" bemoaned Jiang Cheng, sad. Wei Wuxian seemed thoughtful, before smirking.

"I could ask Lan Zhan to move the session to the public library instead of the tiny room he obliges me to be in. We don't have the 5 pm class tomorrow, so I can tell him I have homework to do there and that he can join me at 6 pm ? You two could hid behind a shelve or something or set the camera. How does that sound ?"

Jiang Cheng and Nie Huaisang looked at each other before looking at the same time at Wei Wuxian and nodding once. Wei Wuxian jumped on his feet and smiled, announcing he'd go and find Lan Wangji to tell him. He didn't have to go far, as the young man was still eating silently, alone on his table. Not really knowing why, Wei Wuxian felt a pang of guilt seeing him alone without friends – because let's be honest, Lan Wangji didn't have any friend – and he quickly grabbed an apple from one of the big bowl in display and sat across him, eyeing him and smiling softly before munching on his fruit without a word. He took his time deliberately, to allow the Lan the time to finish his meal, and then grabbed a napkin from Lan Wangji's tray, ignoring the look he got, and put the seeds and middle of the apple in it.

"So, Lan Zhan."

"Wei Ying. What do you want ?"

"Waaah, don't be so cold, my poor heart !" fake cried the shameless man, grasping at his clothes around where was situated his heart. He grinned as the blank face of Lan Wangji let out an imperceptible mimic, sign that he was annoyed by him. He hummed and stopped his antics, suddenly closing his gape between the two of them, his nose almost bumping against Lan Wangji's. The latest immediately put his head back, frowning.

"Wei Ying !"

"Lan Zhan !"

"Shameless…"

"Meh, you're not fun. Anyway, I came to tell you that tomorrow, we don't have the 5 pm class, right ? So, I have to do a bit of homework before our session at 6 pm, so I'll do them in the library. Could it be possible to move our session there ? Same hour, same time and all, just in the library instead of the tiny usual room. I have a lot to do and I'll probably stay after we finished…" said Wei Wuxian, actually meaning it. He had a lot of essays to write and also a project of 15 pages he had to write correctly, not that god awful draft where even him could barely reread.

"Mn."

"Lan Zhan~, I can't know if that's a yes or a no ! Please, I promise I'll behave. I really need that time for study." Wei Wuxian knew he had won when he talked about doing his homework. "So, yes or no ?"

"Yes." Lan Wangji said, before standing up, grabbing his tray and leaving Wei Wuxian at the table. A little disappointed by the lack of reaction, Wei Wuxian pouted, watching the other one put his tray on the moving thingy that took said trays to the washing machine, and sighed before walking a bit outside, inhaling the fresh air of the night.

He ignored the texts and calls he got from his best friend and his brother and hummed a tune he heard on the radio once, walking in the gardens around the dorms. Pets were not allowed, but the school still had an army of bunnies, all loved deeply by the students, and Wei Wuxian was no exception.

He sat on the ground and let the bunnies hop toward him, smiling at them and grabbing careful a spotless white one with light blue eyes. He cooed at it and petted it between its ears.

"You're a handsome one aren't you ? That's the first time I see an albino like you with blue eyes, you're so cute !" he squealed, playing with the rabbit for fifteen good minutes. As he was giggling and silly talking to the rabbit, the movement of white clothes caught his eyes and he found himself staring at Lan Wangji while sitting in the grass, buried in rabbits. He gaped, not expecting to find anyone here at this hour and quickly tried to get up, but Lan Wangji frowned and pushed on his shoulder, forcing him back down.

"Don't move. They'll be afraid." He didn’t say much, but it still made Wei Wuxian gawk. He watched the Lan, dumfounded, as he crouched a meter from him, holding tiny carrots to the rabbits, who all hopped quickly toward him. And when he said all the rabbits, he meant it. All the more than a hundred rabbits were pushing the others to have access to the carrots, a few snapping their teeth at the others. Wei Wuxian smiled and was about to make a joke but promptly shut his mouth, seeing the look on Lan Wangji's face. His constant tiny frown had disappeared and he was left with smooth features, his lips slightly tucked upward in a soft smile. Wei Wuxian found himself breathless, amazed by the sight he had in front of him. He quickly looked away, feeling a blush coming on his cheeks, and petted a rabbit distractedly.

"If you want, you can hang out with us more you know… I mean, I saw that you were often alone, if not talking to Xichen-ge, but he's in the college part so… Wouldn't hurt to stay with friends." Tried Wei Wuxian, inwardly cringing at his own sentence. Lan Wangji said nothing but the energetic one saw the little glance he got, and the look of hesitation in his eyes. He softened and smiled a bit, slowly blinking. "Don't worry, I won't oblige you, come when you want." He slowly got up and waved at the Lan, bidding him goodnight, before going back inside. He didn't catch the lingering look on Lan Wangji's face as he walked in.

Once in his dorm, he got assaulted by his roommates and screeched like a dinosaur as his brother pinched him on his ribs.

"A-CHENG !"

"We called you like, ten times !" frowned Nie Huaisang, snapping his fan shut to tap it on Wei Wuxian's head.

"Jesus fuck, can't even have some liberty in this family !" he pouted and grabbed his pjs, putting them on and climbing in his top bed. The two others followed him up and they all hugged close, not knowing and caring about personal space.

"So. What took you so long ?"

"I talked to him after he finished eating, so I had to wait a bit. Then I decided to go out to walk and played for 15 minutes with the bunnies. Then Lan Zhan came and we talked a bit."

Jiang Cheng lifted his head from his brother's chest and cocked an eyebrow, doubtful. Nie Huaisang groaned as he felt the purple lover move and hid his head in the young man's chest, sinking further in the embrace.

"You talked with Lan Wangji ?" he asked and Nie Huaisang snorted before mumbling something. "What ? A-Sang, get your head out of my chest I can't understand a thing."

"I said, more like A-Xian talked non-stop." He repeated, earning a harmless jab in the ribs. Wei Wuxian engulfed the two in a hug on top of him, his arms secure around their waists, and hummed.

"He seemed lonely."

"What ?"

"Lan Zhan. He doesn't have friends, he's always following Xichen-ge like a lost duckling and when he can't he's just studying, alone. It looks like he doesn’t do anything besides studying, that's just sad…" said Wei Wuxian, felling his throat tightening a bit. He knew what it was like to be alone and having no friends, he had been on the streets for 3 years when he was still a young kid, and if it hadn't been for Jiang Fengmian adopting him, he would probably have stayed there until now. Nie Huaisang sensed his distress and huffed in his collar.

"Well, maybe we could try to talk to him a bit more ?"

Jiang Cheng nodded curtly, but his eyes were soft. He knew the struggles his gege had to go through and even today, he had still some, like his phobia of dogs. He put his chin on his brother's chest and looked at him before approving.

"I don't like the guy, but if I really want to date A-Huan, I have to be in the good looks of his family, and that includes Lan Wangji. And… I mean, it wouldn't be… too annoying for me if he joined… though I'd never hug him like that." He scrunched up his nose, it would be too weird to date Lan Xichen and hug that intimately Lan Wangji. Nie Huaisang and Wei Wuxian were another thing, they knew each other since they were babies, aside Wei Wuxian who joined them at six years old. They always had been clinging on one another and they knew that no matter what, that wouldn't change.

The three kept talking a bit afterward, but they were tired and fall asleep like that, not bothered a bit by the closeness.

 

 

The next morning, they quickly ate their breakfast, early for once, and went back to their dorms to prepare themselves. The three kept snickering at Wei Wuxian trying to put on the long socks and once he had the top part on, he walked in his boxer and socks, wheezing with the others. Jiang Cheng snapped a picture and Wei Wuxian actually put away the socks.

"I think I'll die if I put socks on by these heat during the day…"

"You have legs hair, and if you shave it'll become harder."

"Or you could just… epilate them." Said Nie Huaisang as he showed them wax bands.

"I won't even ask how you got that. We have two hours before Shijie comes in, I'll do it. One leg each ?" said Wei Wuxian. Nie Huaisang quickly nodded and told him to lay on his back.

Let's just say that Wei Wuxian totally 100% regretted it. He'd rather have put socks on. For one hour and a half non-stop, he got tortured and was crying from pain – a big baby if you ask Jiang Cheng. Once it was done, the two massaged his legs with post-epilation oil, – don't ask, Nie Huaisang had it too – then their heard a soft knock. He quickly put on the skirt and Nie Huaisang tried to hold his laugh as he saw the face of Jiang Yanli. She gasped before hiding her laugh behind her hand and closed the door.

"Meimei, you look ravishing ! Ouch, you epilate your whole legs ? Wouldn't have thought you'd do it."

Jiang Cheng snickered at that and gave the makeup to his sister, so she could start her work.

"Alright A-Xian, sit here, close your eyes and mouth and don't move." She then applied some cream on his skin, some powder to smooth out his face, a tiny bit of pink on his cheeks and then moved on his eyes. "Do you want eyeliner too ?"

"Yes !!" He laughed and the two others did the same. Jiang Yanli applied the eye shadow, silver color so it would enhance his grey eyes, put expertly the eyeliner in one go and then the mascara. She then took a tiny bit of highlight on her finger and passed it across each cheekbone and on the top of his nose.

"Done ! Oh, wait, lipstick. I'll go deep red, it will fit your ribbon and hearings."

"Wait, hearings ? I don't have holes !"

"They are clipped hearings, don't worry." Jiang Yanli said and asked him to open his mouth. She applied the lipstick and while she put on the hearings, asked him to dab the surplus on a handkerchief. She smiled and put down his hair, brushing it softly, doing two braids then tying the top half in a low ponytail with the red ribbon, letting his bangs widely out, the strands of the ribbon following the long hair down his waist. "Tada !"

She motioned at him to go see in the mirror of the bathroom and he gasped before looking at his brother and best friend. They took a picture but, expecting themselves to laugh at him, they were awestruck. Nie Huaisang didn't even notice he had stopped waving his fan and gaped.

"A-Xian, if I weren't gay, I'd totally hook up with you right now." He said, and Wei Wuxian chuckled. Which made the boys blush even more.

"Aw come on, don't joke ! I'm not that pretty !"

"A-Xian…" said Jiang Cheng. Wei Wuxian turned toward his brother and saw his frown. "If a guy hit on you, be aware that it is totally possible I'll punch him square in the nose. Rules or not."

"Uh."

"Alright you three, class starts in ten minutes, go now ! And call me if I need to pass by and put some more makeup on !" Jiang Yanli bid them goodbye after giving Wei Wuxian one of her schoolbag, which had tiny flowers, barely seen, on top of it. Lotuses, their favorite. The three went out and nobody seemed to understand the fraud. Rather, they looked at them because of Wei Wuxian, even though they didn't know it was him. After Nie Huaisang's advice, he started to sway his hips a bit and the three dissolved into giggles when they saw a guy watch him and promptly hit his head against a pole, falling backward.

They quickly hurried to their classes, glad it was a full day in the amphitheater. The class during those days was over 100 heads, so the teacher didn't count or called them, he just expected them to be here. Plus, they didn't had Lan Qiren that day, so they wouldn't get scolded. The three sat in the middle of the places and, as the students came in, they started to whisper between them, eyeing the new girl in their class, having never see her before. Jiang Cheng was already ready to bite at them for the looks they lingered at his sist- brother !, but Wei Wuxian calmed him by putting his hand on his forearm.

"A-Cheng, calm down please. There is no need to get angry."

"Tch. They all should get punished. No gossiping allowed." He talked loud enough that the others heard him and the gossips immediately died. The class started and Wei Wuxian squirmed in his seat, not used to have nothing on his legs. It felt weird. Not particularly wrong though. And the feeling of his smooth hairless legs rubbing against one another was downright satisfying.

"Stop moving in your seat, everyone's watching you." Said Nie Huaisang, and even though it wasn't everyone, a lot of their male classmates were indeed watching him. He stilled because he didn't want to attract more regards. Lan Wangji was at the front of the class, but if he saw that the others were watching him, he would turn and see him and the prank would be ruined. So he sighed a bit and took notes lazily, drawing little rabbits when the class was too boring. He also started a drawing from Lan Wangji by memory but couldn't manage his eyes so crumpled the paper with a frown and put it in his backpack. He didn't see Nie Huaisang silently take the paper and put it in his own backpack.

At the break, he gave his – Shijie's – backpack to Jiang Cheng and grabbed the makeup kit, walking toward the girls' bathroom. He knew Mianmian always came in here at 10 am, and he waited for her, watching himself in the big mirror. He truly had some difficulties recognizing himself, and beside the eyes, it was hard to know who he was. He smacked his red lips a bit, smiling and taking a few pictures, before grinning, then cringing a bit, because he could hear Jiang Cheng's laugh if he saw him.

The door opened and he faked cleaning his hands, eyes low, trying not to blow his cover.

"Hey… You have the same makeup kit as I have !" said Mianmian, smiling at Wei Wuxian. She came and took her elastic of her hair to redo it in a high ponytail. "Say, it really looks like mine though…" she squinted her eyes and took the makeup kit in her hands, gasping when she saw her name. About to scold Wei Wuxian, she stopped dead in her tracks when he grinned at her.

"Hi Mianmian !"

"We…Wei Wuxian ?!"

"Shhh !!! Call me… Nie Xiang. Nie Huaisang's cousin !"

"You suck at finding names uh, A-Xiang." She sighed before taking a few steps back, admiring him. "Damn, you totally fooled me here… Your Shijie did the makeup ? You epilated ?!"

"Yep ! And Xichen-ge helped me for the uniform, A-Cheng and A-Sang know too. Please, can you say nothing ? It's a prank for Lan Zhan, and I checked, it's not against the rules to cross-dress so I want to mess a bit with him. I'll buy you desserts from that café downtown for a week !"

Mianmian laughed and nodded.

"Alright, because it's you. Wait, let me redo you hair, the ribbon is falling off." She redid the braids and retied the ribbon, making a long loose bow with it, which was even better than before. "Also, at lunch, if you don't want to smudge lipstick everywhere, try not to eat like a pig. I know its waterproof so it won't come off that easily, but with you, we never know."

"Wait, how will I take it off if it's waterproof ?!" panicked Wei Wuxian but Mianmian rolled her eyes.

"I have some special makeup remover, don't worry. And find me if you have a problem, I'll be closer than your Shijie."

He thanked her before going out and back to his friends. As he took his backpack, it was already time to head to the next class and he sighed before telling the others about Mianmian. The next two hours went pretty quickly, the three kept it quiet to rouse no suspicion, but Wei Wuxian still saw Lan Wangji glance a few time at their group with a frown on his face. He was probably thinking where the hell 'Wei Wuxian' was, and why 'Nie Xiang' was at his seat. The other classmates had asked that too and Nie Huaisang had explained that she was his cousin who came to school for a day only, Wei Wuxian was sick, and that the Headmaster Lan already knew about it – and Headmaster Lan absolutely did not know about it, and they intended to keep it that way.

At lunch, they went in the school's enormous cafeteria, where two third of the school was mixed. The middle schoolers were still too young so they ate in their own cafeteria, but the high schoolers and college students were all together. The three grabbed their tray and paid before sitting at a table in a corner. Nie Huaisang and Jiang Cheng had to put Wei Wuxian between them to protect him from hands trying to grope him in the crowd. Wei Wuxian actually stomped innocently hard on a guy's toes and was satisfied to hear a low hiss.

They ate, talking softly, ignoring the others, when a shadow came over Wei Wuxian, someone standing behind him. Before having the time to turn, he saw Nie Huaisang open his fan and put it in front of his 'cousin' protectively while Jiang Cheng moved to put his right leg in front on Wei Wuxian, protecting him from the shadow's owner. When he finally turned, he saw, to his greatest displeasure, Wen Chao. The same age as their sister, Jiang Yanli, he was the jerkiest jerk they knew of, and he did nothing to calm down the rumors.

"Hello there sweetie, looks like you're lost at the losers' table. Want to have some fun ?" He slurred, approaching him all the while ignoring the two boys beside Wei Wuxian. The latest cocked an eyebrow and held his chin high, a displeasing smile on his pretty face.

"Why, you're leaving ?"

The cafeteria, who had been silent since the Wen heir came in gasped at the remark, rare were the ones who talked back to Wen Chao. Only a handful, and mainly Wei Wuxian did that on a weekly basis, but they actually didn't know that he was Wei Wuxian. He stood up, before Jiang Cheng and Nie Huaisang followed him, and Wen Chao, who was about to bite back, shut himself up. Indeed, Wen Chao was 5'8 tall (1,78 m) while Wei Wuxian was 6 feet tall (1,83 m) and was a tall 'girl'. Said girl smile down at him and grabbed his Shijie's backpack before taking his tray and leaving him here.

The whole cafeteria was silence as the group of three left the place and just before turning at the angle, he saw Lan Wangji, as the good head disciplinarian he was, punish Wen Chao for blocking the way. He snorted and followed his brother and best friend down the hall, snatching said best friend's fan.

They walked down the corridor, heading to their last class, and it went pretty smoothly, if one doesn't count the whispers about Nie "Sharp Tongue" Xiang. Wei Wuxian was rather proud of himself. The art class went on quickly, the little bunnies drawn by Wei Wuxian reminded him of what happened the previous night and the class was finished. The three then went in the library and started to search for a good seat for their prank. They found a little table with barely enough place for two in a corner, hidden from the other tables but not hidden to the point it was suspicious. Wei Wuxian sat there and let the other wander around him to set the camera on.

"Guys, I really have to do those essays though, so…"

"Yeah no problem. The camera is well hidden, we'll stay in the library but not close so we won't be seen. Good luck !" said Nie Huaisang and Wei Wuxian snickered before waving at them. He put on some music and started his homework. It was going rather well, until he realized it was nearly time for his session with Lan Wangji. He closed his book and notepad and pulled out the one about the Gusu Lan School Rules, then got up. He watched Lan Wangji walks in, searching through the tables for him and waited, trying to hide his smile. He truly couldn't find him.

"Lan Zhan." Said Wei Wuxian, barely louder than a whisper, but it was enough. Lan Wangji looked at him with his eyebrows frowned and Wei Wuxian smiled at him. He saw realization really hit him in the face and for the first time since he knew him, Wei Wuxian managed to make Lan Wangji gape at him. He turned on his heels, his short skirts opening around him, and motioned at their table. He walked slow, swaying his hips like Nie Huaisang had told him to do, knowing his long smooth legs were on full display, and sat gracefully at the table, shamelessly batting his eyes at the other student.

"Wei Ying." Weirdly, the sound came out rough, like if he had gotten a bad cold.

"Yes, Lan Zhan ?" asked Wei Wuxian, playing innocent. Lan Wangji stood in front of him, his hold tightening on his backpack's strap. Wei Wuxian could see him trying to find a rule he had broken, but he knew there was none. "Well, maybe we should start ? Like I said yesterday, I have quite a lot of homework." He motioned at Lan Wangji to sit and for the other did, giving him his copying notebook like if he was a robot.

Wei Wuxian thanked him with a tiny smile, he knew he had hit a nerve and was proud of himself. The next two hours went by nicely, although Wei Wuxian noticed the numerous glances he got from Lan Wangji. He also was totally playing with him, sometimes deliberately toying with his hair, another time biting his pen with his red lips, another one looking at student or two with a little sigh and a smile, acting like he thought a girl would. He knew he was driving the other one mad and enjoyed it quite a lot. Near the end, he finally put down his pen and closed the notebook and the rules book, batting his eyelashes at the head disciplinarian and tucked his chin on his hand, elbow near the middle or the little table. That put their noses around eight inches (20 cm) apart. He saw Lan Wangji hold back his breath and even though his face seemed blank, he could see panic in his eyes.

"My, what is happening to you Lan Zhan ? You kept watching me, I'm rather shy, it's a little indecent don't you think ? Maybe it is because you find me pretty ?" He snickered, but the harsh movement of the other made him swallow his laugh. Lan Wangji had stood up abruptly, quickly took his books and pens and put them in his backpack before speedwalking as fast as he could toward the exit.

Mouth agape, he watched the other one leave without a word or a glance behind his shoulder. Next thing he knew, Wei Wuxian had his books in his backpack and his vest on his forearm, running behind him. But the sudden wind made his short skirt fly up and yes, he did scream like a girl. He managed to get Lan Wangji's attention though so, if you ask him, he's said 'meh, worth it'. He put his hands around his skirt with difficulty and took tiny steps, his eyes not leaving his skirt so he could see if something was going up or no. He felt something fall on his waist and lifted his eyes to see Lan Wangji put his own vest around the shorter one, to hide those thighs from everyone's view.

He then grabbed Wei Wuxian by his elbow and pulled him in a building, then into a deserted corridor then into a deserted classroom. There was a dime light, so Wei Wuxian could barely, see, but he did know it was a rather strange behavior for the head disciplinarian.

"Lan Zhan ? Wha-…" But he got interrupted by a mouth crashing against his. Stupefied, Wei Wuxian couldn't move or think or anything for a solid thirty seconds, before he realized that Lan Wangji, Lan "all rules no fun" Wangji, was actually kissing him while he was dressed as a girl in a dark room. Ok that sounded better in his head. He put his hands around the Lan's neck and kissed him back, smiling. Right when he was enjoying it, Lan Wangji pulled back, making the other one chase after those loveable lips.

"Wei Ying." His breath was shakily, his hands on Wei Wuxian's waist too, and the latest felt like a balloon popped in his chest. A warm feeling flooded in his heart and he chuckled, kissing Lan Wangji's nose.

"Well, here I thought I was making you mad. You were just a little frustrated, weren't you ?"

Lan Wangji huffed and let go of Wei Wuxian, walking toward the door.

"Ayia Lan Zhan ! Don't leave me here in the dark, I'm scared !" and that was actually true. It reminded him bad memories. Lan Wangji must have heard it in his voice though because he stopped, hesitated, then came back. "Aw Lan Zhan, you're a true gentlem- hey, hey, what are you doing ?!"

Lan Wangji scooped him up in his arms, bridal style, and told Wei Wuxian to hold on his neck, which he did. He felt the strong hands on his – very much nacked –thigh and his shoulder, muscled arms securing him. As they went outside, he felt his neck and ears and cheeks and just, his whole face blush, because he actually just realized what they looked like. Like Lan Wangji had just managed to get the prettiest girl of the day. And oh boy, they all looked at them like they were aliens and beaten up puppies.

"Lan Zhan, maybe you should let me down…"

"No. Punishment."

"I broke no rules ! I literally searched for more than an hour to see if I could dress as a girl and there is no rule about that !"

"Mn. Am glad there is none. Wei Ying pretty." Said Lan Zhan, glancing down at the smallest one to give him a fond look. And Wei Wuxian melted. He was so stupid. How could he have misinterpreted the looks all these years. Now that he was actually in Lan Wangji's arms, he knew the man had always loved him. And the feeling was mutual, he was just too dense to understand his own feelings.

"A-Xian !?" Jiang Cheng and Nie Huaisang trotted toward them before gapping at the sight.

"Ayia A-Cheng, A-Sang ! Look, your idea got me a boyfriend !" giggled Wei Wuxian, and he poked at Lan Wangji's cheeks when it pinked a bit. "Well, don't expect me to come home tonight !"

"Gross !!!"

Wei Wuxian sticked his tongue out at his brother, but his smile was genuine, and he was truly happy. He finally got what he wanted, without actually knowing he had wanted it. If that wasn't some power move…

"Ugh, I can't understand how you managed to get Lan Wangji by just crossdressing for a day…" sighed Jiang Cheng, lying down against Lan Xichen. Wei Wuxian, mirroring his position with Lan Wangji, snickered and Nie Huaisang rolled his eyes.

"If you want to know, I did not get just him that night, he also got me~…"

"Mn. Wei Ying in skirt is pretty. Hot."

"Gross." Said Jiang Cheng. But Lan Xichen leaned against him, his mouth pressed to his ear and whispered at him.

"I think I would very much like seeing my A-Cheng in a short skirt too… It would be even better with your training whip, Zidian, in hands…"

The words made a shiver run down Jiang Cheng's spine and he blushed furiously. Seeing his lover's gaze at him, he suddenly decided that yes, he'd put that damn uniform on or he'd rather die.
