7:00 AM
It was spring day, a new start for the students as their vacation ended and probably the start of hellish school works once again.

Not that they enjoyed their vacation, but they really didn't—especially Mister Jeon's class. When the infamous 'demonic' Math teacher Jeon Jungkook had announced to his classes to take home the thick Math booklet full of that 'hellish scriptures that even Satan himself found it more hideous' meaning to say the equations that is to be passed once the class starts again. And to study because he'll be giving them quiz once their Math class start again.

The halls of their school was full loud whines and cries of freedom from the students of Mister Jeon's, crying over the fact that instead of them going to those music festivals or family vacation, they'll be answering that book and think about Math unless they don't want to accelerate and hold that piece of paper.

But for Mister Park's Math class, it was heavenly for them. The teacher was an angel, not just by the face but also by his ways.

His students were walking on clouds unlike Mister Jeon's class that are the sounds of students who are screeching out their way to hell.

Mister Park had let them be teens and enjoy their youth, letting off the Math related stuff for them to happily enjoy, their only assignment from him is to take pictures of their vacation and design it into a scrapbook that well—he take advantage of and just take all the materials for himself later.

But on the side note, the students can bring out their creativity.

Then on top of it, every class that Mister Park does not handle was jealous and begging for him to take their class because of his generosity, once he asked students to do that no matter how ugly the vacation work he asked to do, its gonna be a shining A+ on their marks.

Now, Jimin and Jungkook arrived on the faculty room with their hands entwined together, their rings shining through the morning rays.

Yep, they're married.

They got married months after Jimin's return, a they had their dream little civil wedding with their family and friends invited over. Had a honeymoon in Hawaii and had the time of their lives that they waited for six long years.

Jimin still uses his surname Park for school purposes despite being a Park-Jeon now because of their marriage, just for the students so they wouldn't mix him up for his husband. Married happily for six months and both doing the same job in the same school that they don't really much need to separate anymore, much more happier with their friends as workmates.

"Good morning!" Jimin greeted happily to them, his other co-teachers greeting back or sipping their morning coffees.

There's this one strong smell of coffee near him, and he knew immediately whose coffee belongs with.

"You know Taehyung-ah, you and Jungkook could par with the coffee you both drink that caffeine can punch your whole sleepiness outta your body."

Jungkook just chuckled, taking his coffee cup from his table and grabbed Taehyung's coffee jar and poured tremendous amount of black coffee powder that it lessened half the jar, making Tae stand up to whine.

"Jeon! I already told you to stop using my coffee and bring yours!"

Jungkook just went on and poured water from the dispenser, taking a sip of his 'darker and bitter than your soul' coffee.

"Chill, Newton. I only took four table spoons of your coffee, I'd refill it the next time okay? I'd choose the better and stronger brand."

Calling him Newton was Jungkook's new way of calling Taehyung, just because he is a science and physics major that is passionate that he has apples on his bag everytime. Also he's the most elligible bachelor out all of them, the apple of the eye of every female student because of his handsome looks that 99.99 percent of those have a crush on him.

"Just so you know Jeon, four table spoons is equivalent to one fourth in conversion which is 32 grams of coffee. Thirty-fucking two. And the average amount of coffee per cup is 10 grams only which is two tablespoons."

Jimin was trying to stifle his laugh on the childish yet too detailed protest that Taehyung is complaining over Jungkook while the other is just having the coffee of his life.

Might as well join them right?

"Yeah, 'Kookie! You should compensate Tae for the excess 22 grams you took in his 6 ounce coffee jar. Its suppose to be 170 grams that Tae could use for 17 more coffees and now its only 13, considering you two lessened it today. Well, with a little less of two grams." He added, Jungkook rolling his eyes at the two of them.

Hoseok was just on the side, munching his salad sleepily getting annoyed of their coffee grams argument that he can't understand because for fuck's sake, he is a dance and physical education teacher and shoving that in his brain ain't a good idea.

"Y'all fucking stop with that, I'd shove coffee packs in all of your asses. Goddamn look, its seven in the morning and y'all computing math? Really? In front of my salad?" Hoseok took an angry munch of his lettuce, silencing the two then Jimin bursting out for a laugh seeing how grumpy a morning Hoseok is.

"For long years dealing with you Hobi, this one's the best!"

Jimin laughed so loud with his eyes turning to crescents, unknowingly Hoseok already took the banana in his paper bag and peeled it fast to shove exactly on Jimin's mouth choking—like the usual.

"That's what you get, mochi-boi!"

Jungkook almost snorted out the hot coffee from his nose trying not to laugh about how Jimin just took the banana on his mouth so casual and took a bite.

"Heh, I've just done this last night y'know. Could've thought of that boiled egg better in your salad to shut me up than the banana."

If you're some student who was suddenly lost in the faculty room or just deliver a paper, you would've thought that teachers were the one cursing and being noisy acting like chaotic teenagers  than adults their age.

Namjoon entered the faculty room, adjusting his glasses and raising his brows at the chaotic four teachers inside.

"Umm..good morning..? Classes are gonna start at eight, did you guys already sorted your lesson plans?" Namjoon brought down his bag at his table, organizing his stuff and pens he'll use for his lessons later.

"Jungkookie made ours. Were both math teachers that teaches the same year level so there's no need for us to separate plans, just different teaching techniques right?"

Jimin reached for his husband's bag and looked for the lesson plan he made, which he admitted that the very same minute is the first time he'll be reading it.

"Yeah, like how the students prefer Mister Park as a math teacher than Mister Jeon but then regret it down the line when its time to release the report cards?"

Namjoon just told the truth about the two as Math teachers and how contrasting they are despite being a couple that teaches the very same subject.

Jimin was an angel according to the students, a much more lighter atmosphere and a good teacher. But he has high standards, he only gives five quizzes in the whole semester and its all right down that even Albert Einstein will have a hard time to compute. And once you fuck it all up and didn't even reach more than half of it, pretty sure your card has a big fat red mark of F that has the formula of slope because its going down real quick.

"Hey, I give special projects! And I'm kinder than 'kookie." He pouted.

"Your so whiny in the days were I'm still teaching you Math and curse me right down the core of the planet along with those mathematicians but now you're just raining  C's and F's for your students, love."

Well, Mister Jeon is the same. Still terrorizing students, ambushing them day by day with Math works and quizzes that are harder than steel. Still the same seating arrangement for every room with the highest percentage on the back and low on the front seat. He makes sure the students has that formulas imprinted in their brains, and then later its gonna be fruitful because he gives them grades from hard work.

"Well, I'm nice and that's not my discretion anymore if they'll be nice to me too. I teach, make sure they learn in my room. Then its up to them in their houses if they don't work hard y'know. They get what they deserve~"

He sing sang and placed a kiss on Jungkook's cheeks before skipping over to his table to prepare as the time for work is getting closer and the noise outside the room is louder as the students pile in the hallway.

"Hey Yoongi-hyung, wake up! It's 7:40 now, classes are about to begin. Can you tell those kids to go inside their rooms already and stop loitering in the hallway?"

Jungkook tapped Yoongi beside his table to wake him up, still sleeping with the weird anime eyemask covering his eye.

"Hmm...yeah..later.." Yoongi mumbled still half asleep until Jungkook just removed the whole eyemask from his face letting the lights come to him.

"Fucking hell 'kook, I'm still sleeping.." He yawned and just looked around still to lazy to get up on his swivel chair.

"You're having the dream of your life and you still haven't turned in your lesson plan hyung. Get up already and tell the kids to go sit in their rooms."

"Lesson plan? What for? Do I still need that? Damn..we teach almost the same stuff every year anyways."

"Don't tell me you didn't prepare and just slept the whole vacation?!"

"Hmm..yep. Just me and my poodle in the house, having the best time of my life without annoying students around."

Yoongi did get up after a minute and stormed out of the room to yell at the students to get their asses in their rooms with the scrolled paper on his hand.

He saw Jimin stood up and ready to go on his early class and might as well just casually walk with his husband along the way.

"Love, wait up. I'm walking with you." Jungkook scrambled along his things while Jimin waited for him with a smile on his face.

They did walk together casually without holding each other's hands because for professional reasons, having some students greet them along the way and a little chitchat about the lesson.

"So..today's lesson is Linear Equation right? Sweet! That's my favorite topic anyways, gotta teach them how to compute barcodes later too."

"Yep. We're gonna have lunch later at the near cafe?"

"Sure. I didn't get to prepare our lunchboxes earlier, there's no food in the fridge anymore fit for easy cooking. Might as well we go on food shopping when we get home!"

Jimin still wanted their domestic life experience together and him taking care of his husband in some little way like cooking in which—he's still learning by the cookbook.

"You should cook some chicken curry later, I miss that. Might as well eat delicious food before getting stressed out again by checking the papers."

"Your having quiz today? How rude. Those kids were still has vacation hang over." He teased and Jungkook just snickered.

"And you're the angel in disguise of a teacher that later kicks their student down to hell. I wonder if you got those out of hate from me before huh?"

"I did hate you but here we are, married and happy. Oh, you're teaching just by the room next to mine right?" They stopped by one room where kids are now scrambling to go back to their seats when they saw the two teachers near.

"Uh-huh. Tell your class be quiet, my class would need time to think for today. So..see you at lunch?" Jimin nodded and replied,

"See you at lunch."

Even tho they really wanted to give a goodbye kiss, its beyond impossible because students are there. Instead they just smiled while Jungkook walk off to the other room to start terrorizing his beloved students once again.

"Good morning! So..ready for the day class?"

Jimin greeted as the bell rang, smiling at the students brightly, starting his day again as the teacher.

---------------------------
5:00 PM

The classes are already done by three, and the teachers now gathered their things to end their day which pretty much gone well after some academic meeting and submitting their lesson plans to their head teacher, Kim Seokjin.

Taehyung had already gone home early to pick up and feed his dog Yeontan from his neighbor. Hoseok and Yoongi had gone off together, probably on a date and Namjoon went to his graduate school classes for his Masters Degree.

Now Jimin and Jungkook are off their job, back to their usual couple demeanor while walking together to the supermarket with their fingers entwined with each other enjoying the walk with the cherry blossoms and orange sunset.

"Its very beautiful during spring time don't you think so, 'Kookie?" Jimin was enjoying the fresh cold breeze of air, their coats swaying along with the wind.

"Indeed. Its so calm, much more better than winter time."

They stopped on the crossing, waiting for the lights to turn red. Jungkook was too occupied of looking around and the pretty cherry blossoms that he didn't noticed Jimin staring at some male couple pushimg a kid in the stroller.

When the lights finally turned, Jungkook walked off still having his fingers intertwined with Jimin when he noticed that he actually pulled him as his husband is staring at the family in their left.

"Jimin? Love? Please lets walk or else the lights would turn green."

Jimin did snapped out of it and realized how rude he was staring for too long, walking along with his husband till they reached the opposite sides

"O-oh..sorry about earlier. I was just looking at the male couple with a child with them."

The two of them had already talked about the possibility of adopting and forming their family, and Jimin was the one who whole heartedly wanted to have a kid who he can call their own in their house. But they are still earning for it for the adoption fees and legalization they had to face one day.

"I know, and I can't blame you. Its really beautiful, and I'm looking forward for us to be that way too. Maybe not today, but..one day soon." Jungkook smiled and cupped Jimin's cheek to stroke it tenderly feeling the warmth of it in his hand.

"Hmm..we will. Let's go? We can't afford to go home late, we still had to check those papers."

Jimin shared a smile with him and continued their walk on the supermarket and gathered food stocks they need along with some cleaning essentials, some new pens, papers and clips that they'll lose later on and..some condoms and lubes maybe.

It only took them an hour and decided to walk home along with the groceries, Jungkook holding most of the bags. It is night time, walking down in the hall of street lights.

"Jungkookie, is that too heavy for you? I'd carry the other bags, I only have three here with me."Jimin noticed the discomfort of Jungkook carrying five more bags with him, mostly the heavier ones.

"Y-yeah. I guess I need some little help in here."

They stopped by some alleyway, sorting the bags on which Jimin would carry home. There's still a five minute walk and Jungkook could've strained his shoulders futher if he insisted to carry the five heavy bags with him.

"I'll carry three heavy ones and one light. Then you carry two light and two heavy and I think its already oka—"

Jimin was interrupted when he heard a faint noise and Jungkook was alerted too when they heard something, both looking around on where it came from.

"What's that sound?"

It was faint earlier an its becoming louder by this time, and they both darted their eyes in the trash bin.

"Could it be..?" Jungkook set down the bags for a while and approached the bin, with Jimin following him from the back. The sound was getting louder as they were getting closer and when they saw what's beneath it, the couple had their eyes wide and mouths agape.

"A baby?!"
