Lan Xichen hesitantly knocked on the library door, it was already one week since last talk to Lan Zhan after he found out about the truth. isolating himself he was trying to find any solution, awaking whole days and nights not taking any rest and barely eating. Xichen was hurting too much seeing little brother like this and not being able to comfort him, cause he thought Lan Zhan hated him for keeping secret all this years.

"come in" weak voice reached his ears and Xichen entered the room, nodding at Lan Zhan who raised his head from the books and signed to sit down. Zewu Jun looked at him and his heart  broke into pieces noticing Lan Zhan's eyes swollen from crying and tiredness. he slowly moved his hand and landed it on other's, he shook a little but didn't avoid brother's touch. Xichen faintly smiled and finally dared to start talking

"i'm sorry Wangji for disappointing you, i know you could never imagine this kind of act from me" Lan Zhan stayed silent, so he continued "letting Wei Ying to stay here we're hoping his parents gonna be able to come back and save him but it didn't happen. you're still kid then and after he left to his new home i was hoping Wei Ying would never come back here again, deep in my heart"

"brother" Lan Zhan looked at him with hold anger, Xichen lowered his head and breathed out

"i know what you think now Wangji, but you're the most precious person for me. seeing how strong your love and longing was, i could imagine your pain after knowing about truth too. i like childe Wei but i hate watching you suffer. In spite of that i'll support you in everything as long as it's your decision"

"he maybe reason of my pain but he is the reason of my existence too" whispered Lan Zhan "but so you're too big brother" Xichen's eyes filled with tears, hearing this words "you're the one always giving me strength to keep living after our parents death, and while missing Wei Ying, you nor me couldn't express our feelings much raised in the coldness but our connection is unbreakable. brother..." Lan Zhan hesitated "we'll meet each-other in next life too no?"

"why you suddenly talking about this?" smiled Xichen

"just, i'm sure if we will you're going to be my life saver again" Lan Zhan got up and walked towards the door "please follow me to Wei Ying's chamber, i have something important to do" 

*****

"how could you put your blame on me?" Cheng yelled at Wei Ying and chased him, who was running around the bed sticking his tongue out "i'll catch and kill you"

"come on Cheng, it was only thirty lash, can't you bear this much for your lovely brother?" Wei Ying made puppy eyes "i'm Lan Zhan's lover, if he knew i drunk again gonna be in trouble"

"so you sacrificed me no? cause of being obedient lover"

"he keeps telling drink is bad for my health, Lan Zhan became too worrying, like i'm ill" pouted Wei Ying  and screamed as Cheng finally caught him and started pulling his long hair while leaned on top of him, they're too busy childishly  fighting with each-other and couldn't notice Twin Jades of Lan entering the room, Xichen secretly smiled seeing this weird scene but Lan Zhan used protecting Wei Ying quickly touched his sword throwing stern look to Cheng. Wei Ying freed himself and ran to him, holding his hand 

"Lan Zhan calm down, we're just playing" seeing Wei Ying's healing smile his face instantly changed and nodded to Cheng who was almost pale thinking his life was going to end just a few minutes before 

"Jiang Wan Yin i came here to ask for your permission" Lan Zhan tightly held Wei Ying's hand 

"for what?" Cheng was surprised 

"i want Wei Ying to become Lan's family member" calmly said Lan Zhan, not only Jiang Cheng Wei Ying was too surprised too, he stared at him with widen eyes asking for explanation but he just kept talking "i already send someone to inform your parents but as you're the only one here from his family i'm asking permission to marry Wei Ying"

"Lan Zhan you fuddy duddy" Wei Ying gently hit his shoulder "shouldn't you ask me first?"

"no need you'll say yes anyway" Lan Zhan smirked and as expecting he got no denial from him

Cheng confusedly looked at Xichen but receiving warm smile from him he did the same and nodded to Lan Zhan "if my brother agrees i'll too" 

left alone Wei Ying wrapped his hands around Lan Zhan's neck and clung on him, rubbing their foreheads together, Lan Zhan softly captured his lips and left it after a while leaving redness on them "i'll tie you to myself with marrying forever so we can meet again in next..." 

"in next what?" asked Wei Ying and started playing with his hair stuck between fingers 

"you'll know one day" sadly smiled Lan Zhan and hugged him tightly "i hope you'll"

*****

wedding

"Wangji he is ready" Xichen smiled at his brother who was already done preparing, wearing red robes and white headband. Lan Zhan was breathtakingly beautiful as always, the combination of his snow like face and bright red clothes was creating image of ice fighting with fire. his expression wasn't showing anything as always but eyes it was sad and happy same time,  although it sounds unbelievable Xichen knew his brother was someone who could fit too much emotions in his cold eyes. Lan Zhan walked towards him and first time after they became adults he tightly hugged his brother, petting his back. Xichen caressed his hair and tried to stop his tears 

"big brother" whispered Lan Zhan "if i want to leave..."

Xichen shivered on this words but stayed silent and kept listening "if this happens you have to let me go"

"Wangji" he broke the hug and looked at Lan Zhan who was sweetly  smiling "i'm going to my groom now, he must be waiting" following him with eyes Xichen sighed and wiped his tears feeling his brother made decision he was the most scared of. 

***

Wei Ying was standing in front of his parents and Cheng, lowering his head to hide blush running though his face, noticing  Lan Zhan who just entered the  room he became shyer and slowly walked towards him

"angel on the earth" whispered Lan Zhan watching his sunshine who looked even more beautiful with wedding outfit, his long soft hair was half tied up with red-white ribbon portraying their union. long red robes, which was visibly tightened around his slim waist was making him look more tender and elegant. feeling soft touch on his hands Lan Zhan shivered and looked in Wei Ying's  sparkling eyes belonged only  to him. 

"my Wei, my only one" holding his hands tightly Lan Zhan  bowed to Mr and Ms Jiang and walked out with them. leading Wei Ying who's face was already covered with veil in wedding vehicle, Lan Zhan stayed out and followed the crowd by step as it was tradition for the groom. Loud music was accompanying them unable to hear anything but Wei Ying being naughty as always was throwing some dirty comments from the inside teasing his future husband, Lan Zhan was trying so hard to keep straight face, while wishing to hop in and punish him right there.

Reaching the Ancestral shrine and chapel after a while they walked in with lowered head and knelt in front of the god's statues paying respect to them. With First bow they pray for ancestors, second one Lan Zhan and Wei Ying bowed to Jiang and Lan sects elders  and third last one to each-other, declaring love and loyalty.

Facing Wei Ying Lan Zhan looked at Xichen signing something to him, his stare moved at Qiren asking for the permission, he didn't nod but not deny either, little grateful smile appeared on Lan Zhan's face and he took white Lan's headband and red ribbon from Xichen's hands. Surprised whispers were heard from people around but Lan Zhan didn't care and he moved closer to Wei Ying

"I announce you as my cultivation partner Wei Wuxian, Wei Ying, my heart and soul. Promise to always love and cherish you, sacrifice my life for you if it's necessary. My feelings will never fade away, it lasts forever even after death in other life" by saying that he put headband on Wei Ying, causing him to shed happy tears "you're real member of the Lan sect now, you're tied to me forever"

"I'll announce you as my cultivation partner Lan Wangji, Hanguang Jun, Lan Zhan" Wei Ying giggled and added with low voice so only Lan Zhan could hear "my only Lan er gege, i'll treasure your love the most, keep your company everywhere and every time. Share happiness and pain with you and if death gonna separate us i wish to die before you" Wei Ying tied his red ribbon on Lan Zhan's wrist and whispered at his ear "tied forever, for all lifetime"

*****

Wei Ying was sitting on the bed patiently waiting for his already husband, looking back he couldn't really imagine married into Lan family, which was the most boring one in the world for him, with too many rules and forbid but love... his love towards Lan Zhan could bare anything. this unexpected feelings totally changed and lightened his life, he was happy too happy that it was scaring already. hearing door sound he raised his head to meet Lan Zhan's eyes full of adoring and passion, slowly walking towards Wei Ying he was unable to stop staring at him

gently  wrapping arms around his slim waist Lan Zhan planted soft kiss on Wei Ying's forehead, resting his lips there for a while he could hear their hearts beating fast in sync against each-other, removing tie from Wei Ying's hair it messily fell down on his shoulders and Lan Zhan shivered feeling mesmerizing smell coming from his body. leaning closer he breathed in deeply and run his tongue on Wei Ying's ear causing him to moan. placing him on the bed Lan Zhan held his hands and sweet sounds escaped from his mouth, realizing he was singing Wei Ying's eyes widened in surprise and smiled widely listening the softest voice he had ever hear. 

If I use an entire lifetime to wait

Hoping for a single glance from you

When dreams wake, don't want to be left with nothing

Waiting on those glory days of youth

Accompanied by a wordless tenderness

How much I want to hold your hand in this moment

Lan Zhan was singing all his heart out, remembering days he was dreaming about Wei Ying but waking up without him alone as always, tightly hugging the pillow he wished for even only one chance to see or touch him. now he had Wei Ying this close but yet too far, fear of losing him very soon was eating Lan Zhan from inside. finishing song he faintly smiled and waited for his reaction. Wei Ying didn't say anything but hopped on his lap and captured his lips devouring it with full passion, Lan Zhan pulled him down and slowly started removing his robe, exposing his tempting soft skin he bent down and covered his neck with wet kisses, Wei Ying gasped and whispered "it was too beautiful Lan Zhan, did you write if for me? About missing me?"

"mn"

"the name of the song, what is it?"

"guess yourself" was reply and strong bite on the chest followed this words, Lan Zhan moved down hungrily licking and tasting his pink buds, giving too strong pleasure to Wei Ying "finally i can fully feel you" making Wei Ying  wrap around his waist Lan Zhan ran his hands thought his whole body, hungrily exploring  it while nonstop kissing his face. lust and hotness was totally owning them now, gently sliding his hand between Wei Ying's thighs Lan Zhan started preparing him trying to not hurt. laying him down again Lan Zhan positioned himself and whispered at him "our hearts and souls are already joined, are you ready to make our bodies one too? i desire you Wei Ying, i'm dying to fully own you"

"i'm Lan er gege" Wei Ying moved his hip up, rubbing their trembling bodies together "don't wait anymore, just own every part of me, make me sing your name and beg for mercy"

"shameless" grinned Lan Zhan and entered him slowly, fully filling his insides. tears of pain and happiness dropped from Wei Ying's eyes, on every deep thrust he was tightening grasp around Lan Zhan's neck and kissing him more hungrily. investing tongue in his mouth and sucking it tastily Lan Zhan hastened his movements causing Wei Ying to nonstop moan his name "mine only mine" he was whispering and leaving biting marks on his neck and chest, waiting too long time for this night Lan Zhan couldn't get enough, his body was acting on his own, crushing and devouring Wei Ying between his arms, pulling their bodies together as hard and close as he could, marking every part of his, trailing his tongue everywhere he could reach. Wei Ying was gasping, shivering under his unstoppable passion and desire, every touch of Lan Zhan was making him more and more excited, fully welcoming him to do anything he wanted, cause he was willing for more too.  finally wasted Lan Zhan fell on his chest and closed his eyes breathing heavily, Wei Ying softly caressed his hair and whispered with weak but sweet voice

"Lan Zhan aren't we going to keep doing this for our whole life, why you ate me like it was last time?" he giggled cutely "you beast"

Lan Zhan held him in tight embrace and softly kissed his swollen lips "we'll my love, sure we do"

feeling all exhausted and dizzy Wei Ying soon fell asleep, smiling in his dream. Lan Zhan sighed and few hot tears escaped from his eyes, removing hair from Wei Ying's sweaty forehead he moved a little up and leaned his face at his chest "it beats for you Wei Ying, my heart will always beat only for you my sunshine"

I didn't have much information about wedding traditions, so don't mind if I write something wrong. Rest is my imagination. I can never be satisfied enough while writing about WangXian but hope it wasn't too bad 😅
