At exactly 6:00am Jaemin’s alarm goes off signalling him that it’s time to get ready for his first day of junior year. Jaemin did his usual routine and they went downstairs to eat breakfast with his brother, Jaehyun.

“Good morning hyunnie hyung” Jaemin says taking a seat “Mornin’ Nana, are you excited for your first day back?” Jaehyun asked before placing Jaemin’s breakfast in front of him. Jaemin simply shrugs and starts eating. “Well I hope everything goes well.. I heard Lee’s brother is-

studying at your school this year. Stay clear of him, if he’s like his brother then he’ll be nothing but trouble.” Jaehyun warns him as he grabs his plate and puts it into the sink. “Isn’t it wrong to judge someone off of someone else’s wrong doings? And are you ever going to-

tell me what happened between you and Doyou-“ “No and no. And how many times do I have to tell you not to say his name?” Jaehyun says cutting off Jaemin who just rolled his eyes at his childish antics and grab his school bag. “Ok whatever, I’ll be wary of him if that makes you-

feel any better, but I got to go! Have a good day at college hyung!” Jaemin said running through the door. “That kid I swear.” Jaehyun says shaking his head with a smile. Soon his phone went off signalling a call and to his delight it was Taeyong “Hi there Taeyongie~”

“Ok, so you have your phone and my number is on speed dial, correct?” Doyoung says as he drives to Neo Tech High. “Yes, Doie hyung” Jeno responds begrudgingly. “And you sent me a copy of your schedule, correct?” Doyoung says as he parks the car, “yes hyung” “and you will text me-

a report of what happens inbetween classes?” “Yes- wait what! Hyung!” Jeno exclaims in shock. “What? I need to be sure your fine Jeno!” “But Doie hyung that’s to much to do on the first day!” “I never said you’ll only be doing reports today..” Doyoung says looking at Jeno.

“Hyunggg~ please don’t make me do this” “Jeno it’s for your own-“ “I’ll tell Jungwoo hyung” Jeno says taking out his phone. “No! .. ugh fine.. jus-just text me at some point of the day that your fine please?” Doyoung says smiling kindly at Jeno. “Of course I will, I should go-

now hyung. Bye!” Jeno said giving Doyoung a quick hug before exiting the car and entering the school building. Jeno made his way through the schools halls, glancing a poster for basketball tryouts that will take place this week, he’ll definitely have to tryout for that.

Jeno was just about to turn the corner when he saw this beautiful boy at his locker, Jeno doesn’t know what came over him, but he walked over and lightly tapped his shoulder. “Hey- um. I’m new here and I was wondering if you can help me find my way around?” Jeno says shyly and

internally facepalms. “Oh of course! My names Jaemin by the way!” the boy, Jaemin, said bubbly. “God he is so cute..” Jeno thought before responding with his own name. Jeno and Jaemin first go to Jeno’s locker before they start the tour. Jeno couldn’t stop laughing and smiling

at Jaemin’s cuteness as he rambled about the stories or unforgettable things that happen around the school. While Jaemin couldn’t stop giggling at the cute noises Jeno makes when confused or blush anytime Jeno eye smiled. Eventually they found out they share the same classes and

decided to head to their shared home room only to be greeted by many gasps and stares. Soon enough Mark grabbed Jaemin and pulled him away from Jeno, Jaemin was going to fight back, but Mark gave he ‘the look’ which means he wasn’t joking around. Not long after, Hyuck wrapped his

arm around Jeno’s shoulder and pulled him to sit beside him on the opposite side of the class where Jaemin sat. “Na Jaemin, your are an idiot!” Mark exclaims in a hushed tone. “Mark I did not come to school to be attacked-“ Jaemin starts off, “well too fucking bad Nana! That’s-

what you get when you walk into class with Lee Jeno aka your brother’s rival’s brother, that he has spent the entire summer telling to stay AWAY from!” Mark says annoyed. “Wait.. he’s Doyoung’s brother?” Jaemin said looking at Jeno how was also looking at him with the same-

expression, confusion, “yes he is so stop looking at him!” Mark said as he pinched Jaemin, making him wince and turn to pay attention to the teacher who just walked in. At lunch, Jeno was swarmed by boys and girls with love confessions and invitations to lunch, but he turned-

them down and left to the hall way where he saw Jaemin put up more basketball tryout posters. Jeno couldn’t help, but stare at his body, he approached Jaemin because he thought he was cute, but now.. he looks down right ethereal. his skin is a beautiful milky white, his-

big doll like eyes, he could practically see stars in them, and his lips, soft and pump looking. He knows he shouldn’t be around Jaemin, but in his defence the explanation of Na Jaemin his brother gave him doesn’t fit him in the slightest. Maybe he’ll talk to Jaemin to see-

where they stand with one another “Hey Jaemin-ah~” Jeno sweetly. Jaemin smiled at Jeno “Hi Jeno-ya~!” “I was wondering if we could talk? If your not busy of course” “Oh, sure! Here there is an abandoned classroom over here. We can talk in there.” Jaemin and Jeno make their way-

into the old tech lab, Neo High is known for it’s amazing technology, so they made the tech lab into a bigger classroom leaving this old one behind, though it is cleaned on regular, waiting for it to be used for something. “So Jaemin-“ Jeno starts “Wait, Jenooo! Call me Nana-

everyone does” Jaemin says with a pout on his lips making Jeno laugh lightly. “Ok, Nanaa~” Jeno says teasingly, making Jaemin blush and shiver from how his name rolls off of Jeno’s tongue. “Are we friends? No I mean, are we like our brothers? Should we hate each other too?” Jeno-

asked questioning himself as well “Well do you hate me? Cause I don’t hate you and I mean we don’t even now why our brothers hate each other” Jaemin reasons “That’s true, but what about school and our friends? If they find out we’re friends our brothers will surely find out?”-

Jaemin nods his head in contemplation before answering “then let’s act like we hate each other in front of others, but use here as our safe spot.” Jaemin says excitedly. “Ok then Jaemin-ah~” Jeno says teasingly before stand in front of Jaemin. “Your really cute you know-

☕️ thoughts so far ☕️

“Your really cute you know” Jeno says making Jaemin blush. “Y-you really think so” Jaemin replies looking down, poking his fingers together, “yeah I do” Jaemin heard and he swears his heart started to beat faster. Suddenly Jeno’s phone started causing Jeno to sigh

“it’s Doyoung hyung, I’ll catch you later Nana” Jeno says making his way to the door, phone in hand, but not before kissing Jaemin’s cheek leaving him flustered, while Jaemin gives him a quiet “goodbye”. If Jeno was gonna keep flirting with him, Jaemin will die a early death.

time skip: three weeks ☕️

Jaemin and Jeno have been able to keep their friendship a secret from their friends and brothers for 3 weeks now and they had grown even closer now. Jeno made the basketball team, he’s actually the captain, luckily Jaemin was able to watch the tryouts since Mark was trying out-

too. For Jaemin, to say Jeno was good at basketball was an understatement, he is amazing. Jaemin couldn’t even tell you how much times he almost cheered for Jeno out loud, but sadly he couldn’t or else that would cause some unnecessary attention. They also meet up-

two days a week to eat lunch together in the old tech lab. Jaemin’s accuse to Mark is extra studying, which isn’t a complete lie since Jaemin helps Jeno in the subjects he struggles with. While Jeno tells Hyuck and his new friends and teammates, Chenle and Jisung, that he wants-

to get extra practice in. On weekends they visit Jaemin’s favourite coffee shop to study of just hang out or they’ll go to this cat shop that Jeno is fond of to pet, feed, and take care of the cats. Jeno and Jaemin have both grown feelings for one another and it’s pretty obvious-

that they like one another, but neither knows how to act on it. Jaemin was tired of act like they don’t feel anything for each so he asked the one (1) person he could trust and that one person is no other than his favourite hyung..

Lee Taeyong. “Yongie hyung~!” “Jaeminnie!” Taeyong’s voice rings through his phone. Jaemin was currently in his room, Jeno is supposed to come over, Jaehyun is actually on his way to Taeyong’s to go on a date. Jaemin knew it was risky to bring Jeno over, but he planned to tell

Taeyong everything, so he knew he’ll get help from him too. “Yongie, really need your help. Jaehyunnie hyung’s rivalry with Doyoung hyung is stopping me from hanging out and possibly dating Doyoung hyung’s brother~” Jaemin says in a whiny tone. “Oh Jaeminnie~ you poor-

baby, well I think you should sort out your feelings with this boy and get Doyoung and Jaehyun together and tell them how you both feel!~” Taeyong says kindly “Oh my gosh! Yongie your the best!” Jaemin said excitedly bouncing on his bed. “I know~ that’s why I’m your favourite-

hyung. Also be sure to tell those two from me that they better make up or else! You and your future boyfriend’s happiness is more important than their bs.” Taeyong says with a huff. “Hyung, do you know why they hate each other?” Jaemin says carefully, “Oh uh- oh no Jaeminnie-

Jaehyun is here now I got to go! Bye~!” Taeyong says in a rush. Jaemin sighs, as expected he thinks, just as he thinks this the door bell rings. “Oh Jeno!” Jaemin remembers and jumps off his bed to let the boy in. “You know that actor looks a lot like you?” Jeno tells Jaemin.

They are watching a drama called “The Way I Hate You” and the male lead looks like Jaemin. “Pfft no he doesn’t” Jaemin denies “Anyways, you said you had something important to tell me, right?” Jaemin asked facing Jeno. “Ya I do, Jaemin, I know we haven’t known one-

another for a long time, but I feel happy around you and I can say whatever is on my mind without feeling judged. I absolutely suck at english and yet you have so much patience with me and.. Na Jaemin.. I think I’m in love with you. And I want to tell our brothers about us-

I mean, their our brothers, if they really love us then they’ll be able to let go of their rivalry for us right?” Jeno let’s out a shaky breath before saying “but really, Jaemin, I love you” Jeno said with sincerity in his eyes. Jaemin tried to hold back his tears, but failed-

and ended up crying as he repeatedly said that he loves Jeno over and over as Jeno holds him close to his chest and whispers loving things in his ear. After an hour of hugging and kisses, Jaemin told Jeno about Taeyong’s plan and the decided that today is good day to do it

Jaemin texts Taeyong asking if he could get Jaehyun to come home and come along too, while Jeno calls Doyoung asking if he could pick him up from Jaemin’s, luckily Doyoung didn’t know Jaemin is Jaehyun’s brother. Both parties got confirmation that the brothers are coming, so-

all they have to do is wait. Doyoung was first to arrive, Jaemin opened the door because he expected it to be Jaehyun and Taeyong, he was wrong. “Hi there~ you must be Jaemin! I’m Lee Doyoung, Jeno’s hyung” Doyoung says with a gentle smile. “Oh, uh. Hi I’m N-Jaemin!, Jaemin!-

just Jaemin!.. yah” Jaemin stutters out. Doyoung was about to say something when Jeno pulled him in and gave him a hug. “Hi Doie hyung! Go sit in the living room, Jaemin and I have something to tell you, we’re just waiting on others.. ok?” Jeno asked as he guided Doyoung to the-

living room “uh ok I guess?” Doyoung said reluctantly and sat down. Jeno walked back over to Jaemin and laughed “You really suck at this babe~” said teasingly. “stoooop being a meanie” Jaemin whined. The door bell rung and Jaemin quickly shooed Jeno away as he opened to door for-

Jaehyun and Taeyong, “Hyunnie hyung, Yongie hyung! I glad your here!” Jaemin says. Jaehyun looked confused and was going to say something, but Taeyong didn’t give him a chance to. “Where is he? In the living room?” “Yup!” Jaemin says as both him and Taeyong drags Jaehyun to the-

living room, Jaemin quickly went beside Jeno and Taeyong sat Jaehyun down on the couch on the opposite side of Doyoung, Taeyong sat inbetween them. “Jeno, what is going on!?” Doyoung demanded instantly noticing Jaehyun “Yah! Na Jaemin! Why is he here!?” Jaehyun said ignoring-

Doyoung’s glare. “Both of you shut up and let them speak!!” Taeyong yells making the two of them wince before listening to we their brothers have to say. “Thank you. Ok proceed Jaeminnie~” Taeyong said sweetly making everyone visibly shiver. Taeyong can be really scary sometimes.

“Thanks Yongie, let’s get straight to the point. For years the two of you had this stupid hatred for one another and control both me and Jeno’s lives because and yet we don’t know why you hate each.” Jaemin starts “Yeah, Jaemin is right. You make us apart of your issues with-

each other, but you can’t even give us a reason, a actual reason, for you to hate each other. Normally I wouldn’t care, but I do care cause this isn’t healthy for you two to live your lives hate one another and it’s going to obviously affect Jaemin and I’s relationship.“

“Wait what do you mean your relationship?” Doyoung asked calmly,Jaehyun nods his head in agreement, “Obviously it means their dating” Taeyong says enjoying the surprised reactions from the two brothers. “Jaemin, when did you two Starr dating?” Jaehyun asked shortly

“Just today actually, Jeno confessed that he loves me and I told him I love him too. I’m happy with Jeno, hyung and I don’t want your issues with Doyoung hyung to get in the way of that.” Jaemin says and looks at Jeno to finish it off. “And hyungs, don’t you think it’s time to-

let go of this pettiness and hatred for one another and start a new?” Jeno asked. Doyoung sighs and nods “You know what little brother? Your right!” Jaehyun laughed “We had this rivalry between us for about four years now, right?” Jaehyun smiled facing Doyoung. “Five years-

actually, pretty stupid huh?” Doyoung said smiling, Jaehyun agreed and laughed lightly with Doyoung. “Ok! Now Jaeminnie, Doie, help me cook dinner!” Taeyong says about to leave when Jeno called him. “Wait, Taeyong hyung, how did you know Doyoung hyung could cook?” Jeno asked

“Oh! You don’t know? Jae, Do and I went to Neo High together! We used to be best friends till Jaehyun and Doyoung’s rivalry started.” Tae says “Ok I think that’s-“ “Do you know what their rivalry was about?” Jaemin asked cutting off Jaehyun. “The rivalry was about who can get-

their first kiss before senior prom.” Taeyong said simply as Doyoung and Jaehyun’s head fell. “Really? That’s it” Jeno said crossing his arms giving his brother a judgmental stare. “Oh no! That’s just part of it! The reason reason is the THEY were each other’s first kiss!”

Taeyong laughed out as he ran out the room getting chased by both brothers. Jaemin and Jeno stared at each other before laughing so hard that they fall on the floor.

time skip: two months later ☕️

Jaemin and Jeno were even more in love with one another and their brothers were best friends again. Doyoung is spending the night at Jungwoo’s, he finally manned up and asked Jungwoo out, they’ve been dating for a month now. Jaehyun and Taeyong’s anniversary is today so Jaemin-

is sleeping over at Jeno’s. Currently they are cuddling and sharing a few kisses. Jaemin starts giggling as Jeno lightly kisses Jaemin necks. Jeno starts sucking on Jaemin’s skin leaving bruises. “Jaemin can I-” “Go ahead Jen” Jaemin sighs as Jeno pulls off his and Jaemin’s shirt

I knowww I’ll try to update tmrw, if not then, definitely before the end of the week🤧🤧

Jeno stared at the love bites on Jaemin’s neck and collarbone. Seeing the bruises contrast Jaemin’s beautiful milky skin, it proves that Jaemin belongs to him and him alone. Call him possessive, but he can’t help it, he is a ethereal beauty- HIS ethereal beauty

“Jeno-ya~ p-please” Jaemin calls out for him while running his fingers down his chest and arms “use your words Jaemin-ah~” Jeno says teasing Jaemin by nipping at his ear. Jaemin whines before saying “please f-fuck me d-daddy”. Jeno groans, feeling his bulge grow big due to the-

younger’s words. “Anything for you Baby” Jeno says as he pulls Jaemin’s pants and boxers down. Being exposed, Jaemin shivered as Jeno lifts his legs to get a better look at his pretty pink hole. “So pretty and tight for me baby boy~, lets stretch you out a bit yah?” Jeno said

as he lowered himself down to Jaemin’s pretty little hole and flicked his tongue once, then twice, before devouring Jaemin’s pink hole. Jaemin turned his head to the side and tried muffling his loud moans with the pillow, but Jeno quickly notices this and pulls the pillow

away, he then shoves two fingers into Jaemin’s warm mouth. Jaemin wraps his tongue around his fingers and continues to moan loudly, Jeno feels his body get hotter as he groans hole. He quickly slips his slicked fingers into Jaemin and lean down to claim Jaemin’s luscious lips.

Jaemin’s back arched while crying out incoherent things as a powerful climax hit him hard. Jeno spread light kisses on his face before asking if Jaemin still wanted to continue. He of course said yes and grabbed Jeno by his hair and kissed him with passion as Jeno took off his

pants and boxers throwing them to the floor along with Jaemin’s already long forgotten ones and aligned himself with Jaemin’s hole. “It will hurt a bit Minnie..” Jeno say slowly, giving Jaemin time to back out of it, but of course Jaemin “It’s ok Nono, I trust you” Jaemin says

wrapping his arms around Jen’s neck as they share a kiss Jeno enters Jaemin, after a minute of adjusting to half his length, Jeno pushes in full making Jaemin whine. “God, I feel so full Daddy!” moving, trying to create some friction, “Just wait till I breed you Baby boy”

Jeno says cockily as he snaps his hips forward. “D-daddy! Faster! H-Harder!” Jaemin moans out causing Jeno to let out a growl before doing as his baby says. The only thing that can be heard throughout Jeno’s bedroom is Jaemin’s mixture of whines and moans, Jeno’s loud

groans and the growls held at the back of his throat, the small squeaks of the bed as Jeno’s thrust become harder and lastly Jeno’s balls rapidly slapping Jaemin’s skin. So enough they both came together, Jeno still thrusted lightly, not to hard since Jaemin is sensitive from

climaxing twice. “Jen.. come cuddle with me..” Jaemin says trying to catch his breath. Jeno quickly cleaned them up before wrapping Jaemin into his arms. In their half asleep state, they exchange “I love you’s” and short passionate kiss before drifting to sleep.

time skip: the next day; at school ☕️

“Jaejae! You and Jeno fucked, didn’t you!” Hyuck says as Jaemin entered the tech lab. He blushed and hid his face in Jeno’s neck, who patted his head as he laughed at his reaction. “Hyuck! There is minors here!” Mark exclaimed as he walked into the tech room and looked

at the two youngest of the group who were fighting the obvious blush on their face after hearing that. Hyuck simply shrugged as he listened to Chenle, who continued to talk about his cousin Renjun who will be coming to their school. After Jaemin and Jeno became official

they befriended one another’s friends and used the old tech lab as regular hang out spot for them all. “Hyuckie hyung, how do you know that Jeno and Jaemin hyung did.. well.. that..” Jisung says stammering at the end. “Oh Sungie~ when a couple fucks- I mean, has sexual

intercourse, they have this glow about them, Jeno is good at hiding it.. Jaemin, not so much” Hyuck said with a little laugh. “That’s disgusting” both Chenle and Jisung say as they make a face of disgust. Jaemin just smiles at the two, he never noticed how cute they look together

“Lele! You and Sungie should start dating too!” Jaemin day with excitement. “Nana hyung, Chenle and I are just friends” Jisung said with a sigh as Chenle nodded in agreement. “Yah! We’re best friends, until Jisung likes me back, we’ll stay as friends!” Chenle says, “Wait..

so, you do like Jisung?” Jeno asked. Chenle simply nodded and not long after he was pulled out of the classroom by Jisung. Jeno, Jaemin, Hyuck, and Mark took note of the red face their youngest friend was sporting and let out small chuckles as the two left. “No everyone is a-

couple!” Hyuck exclaimed happily, “What do you do mean Hyuck? Only Jaem and I are a couple- er, well Jisung and Chenle are work it, but still!” Jeno said. “Oh. Yea! We forgot to tell you! Hyuck and I are dating.” Mark says in a nonchalant tone, “WHAT! WHEN!?” Jaemin shouts.

“Stop shouting Jaemin-ah! It was the day you and Jeno were to busy hooking up to answer me and Marks calls!” Hyuck said glaring at the pair “Marky here, took me out for dinner and admitted his long time feelings for me!” Hyuck said confidently. Mark huffed before grabbing Hyuck

by the back of his collared shirt and dragged him out of the classroom mumbling something like: “it was you who confessed but whatever..” under his breath. Jeno and Jaemin smiled at one another as Jeno wrapped his arms around Jaemin and leaned against the desk.

“I love you Na Jaemin” “And I love you, Lee Jeno” the two share a kiss which get heated quite fast, Jeno pulls away, “Can I take you on this desk?” Jeno asks smirking as he lifts Jaemin on the desk. “Logically this is very unhygienic.. buuut” “buuut~” Jeno says smirking evilly

Jaemin moved closer to Jeno’s ear and whispered “Screw logic and fuck me Daddy~” Jeno instantly attacked Jaemin’s lips and well, let’s just say Jaehyun and Doyoung got an interesting call from Neo Tech High.
