Goodbye Yesterday

"I'm back, Koro-sensei..."

A light blue-haired man with equally blue eyes stood still in front of the old single-storey building which seemed well-kept and less dilapidated than he thought it would be considering seven years had passed. This very building was where his classes in junior high took place – the infamous class 3-E. Shiota Nagisa, former student of 3-E, finally returned as a trainee teacher at one of their local high schools after graduating from university.

I did it, Koro-sensei.

He finally became a teacher.

I feel like I'm a step closer to you now.

Just then, he caught sight of another person standing not too far in front of him with their eyes shut, allowing the spring wind to blow past their face, strands of fiery red hair tousled around, dancing to the air.

Crunch.

Nagisa unknowingly stepped on some dry leaves, and the crunching noises alerted the other person soon enough. He calmly turned around and Nagisa could finally see his face, the amber eyes widened by a fraction before the redheaded man spoke up, "Nagisa?"

Wait. Those familiar sharp yellow eyes. That familiar scarlet hair. That familiar voice.

"Karma..!" Nagisa rushed towards the man and greeted him with the widest smile he could possibly muster, light cerulean eyes sparkled brightly like that of a child's. "It's been so long! How have you been?"

The person standing tall in front of him was named Akabane Karma, his friend slash ex-classmate from Kunugigaoka Junior High class 3-E. Over the years, he was one of the few friends Nagisa still kept in touch with, most probably due to Karma's persistency in pestering him with calls or texts at ungodly hours from time to time.

Karma automatically brought his hand on top of Nagisa's head before ruffling the pastel blue hair, now nice and shorter than before. "I've been fine. But wow, you didn't change at all since I last saw you. Except for your shorter bangs. Did you even grow in height at all?" The redhead slyly slipped the sensitive question in at the end with a trademark smirk on his lips.

"I-I did! Don't be so rude..." Nagisa spluttered, face easily turning red from humiliation. Over the course of seven years, he had only grown in height by a centimetre, as laughable as it may sounded. He was only 160 cm tall right now (a pretty pathetic height for a twenty-two year old man if he had to say so himself). Meanwhile, the red-haired devilish man towering over him easily reached a proud height of 185 cm from his last height of 175 cm.

"As always, you've never fail to surprise me with your superb assassination skills. I couldn't even sense anyone behind me just now. Must be getting pretty rusty after all these years." Karma laughed a little as he removed his hand from Nagisa's small head. And the bluenette caught himself staring at the other in awe. If before Karma had this wild psychotic look on his handsome face, he now retained some maturity in his facial expressions, amplifying his degree of handsomeness by a thousand-fold.

Great looks, great height and build and a challenging but great job nonetheless as a civil servant in one of the top bureaucracies in the country?

"Dear god, aren't you being a bit biased nowadays..." Nagisa mumbled to himself as they both made their way to the building entrance, Karma was a bit distracted to even reply with his usual witty remarks.

And just then, Nagisa saw what made the other man stared ahead in complete silence; their old classroom, left just as they both last seen it – the desks and chairs aligned in a few rows, the teacher's desk in the front middle, the blackboard and a box of colourful chalks nearby, some streaks of sunlight peeking through the window curtains creating some kind of shadowy effects and the whole place seemed to gleam in a majestic gold.

"How nostalgic..."

The trainee teacher then eyed his red-haired friend who sauntered to the teacher's desk before leaning against it, one hand already reaching for a piece of chalk.

The sound of chalk scraping across the blackboard resounded in the silent classroom and Nagisa stood there listening in great nostalgia. In school nowadays, they used whiteboards and markers – a pleasant change in terms of ease to clean but to Nagisa, that very sound was one of the few connections they had had with their beloved sensei in their chaotic everyday classes before his timely death at the hands of no one else but Shiota Nagisa, his very first and last assassination.

"At 22 years old, Nagisa Shiota is only..." Karma voice's trailed off as he continued to write something on the board and Nagisa's eyes curiously followed suit.

"...160 cm tall...? Wait, where did you-!?" Nagisa frantically rushed to the front and reached for the duster. "Erase that immediately!"

Karma swiftly grabbed hold of the sought item first, placing it up high above his head and of course, out of Nagisa's reach, "No way~ Bull's-eye, huh?"

The poor man, shorter than his sadistic friend, jumped a few times as he tried to reach the duster. Landing on the wrong side of his foot, Nagisa tripped in front if Karma, bringing him down as they both fell.

As clichéd as it could get, both of them fell to the ground and with Nagisa on top of the redhead. "Hand it over, Akabane Karma!"

"No~ and ow, did you just used me as a cushion for your butt?" A groan could be heard underneath the bluenette but he feigned ignorance.

"I said – give it to me..!" Nagisa tried to snatch the duster away by force but ultimately lost to the owner of the longer limbs.

A short sigh escaped his lips. "Be a good boy and give it to sensei, okay?" He tried again, using the approach as an educator. Why, at times he felt as if he's dealing with a five-year old rather than someone of equal age when it came to Karma?

"Alright, I'll give it to you. In return for a hot kiss from you first. What do you say, Nagisa-sensei?"

"EXCUSE ME!" Immediately, Nagisa turned a deep scarlet red from Karma's absurd request. He didn't bother replying but continued to reach for the duster. Though the redhead wouldn't budged a bit, not without getting what he wanted.

"H-how did we got into this mess again...?" Nagisa panted and long stopped squirming underneath the redhead. Karma was a strong as a boulder. But that went without saying of course.

"By fooling around, probably?" Karma stated the obvious of all obvious and Nagisa had the sudden urge to facepalm.

"Oh, come on. It's not like you mind the kissing and getting all intimate before this?" The redhead accused, sporting an unsatisfied look.

"Pardon me but yes, I do mind!" Nagisa retorted back quite heatedly.

"Even though you did it quite easily with Bitch-sensei and Kayano before?" Questioned Karma, both his gaze and voice layered with sarcasm. Nagisa bit his lower lip at that.

"That and this are two different things!"

"How so?"

"Ah, so infuriating!" He angrily turned away, avoiding further eye contact with the devilish man.

"Tell me, how is it different now?"

Nagisa grumpily dropped the conversation and instead focused on breaking free from Karma's iron grip, only to give up after his fourth attempt, knowing well a futile effort when he saw one. "Karma-kun, please. Would you be so kind as to unhand me?" He coolly said, switching to his teacher persona yet again.

"What if I say no? Will sensei punish me this time?" Karma naughtily answered, and Nagisa almost missed a quiver in his voice. His face was slightly flushed than usual, golden honey eyes glazed over, as if longing for something.

Don't go testing the limits of my patience, Nagisa.

It wasn't as if he planned on keeping it a secret, he just couldn't be bothered to fess up to the oblivious bluenette. That he had had a crush on his gentle yet terrifying assassin prodigy of a friend since their first year in junior high. Nagisa squirming in his hold like a helpless little mouse oddly urged him on even more so. "..then, let's not be just friends anymore."

The redhead's cryptic words startled Nagisa if anything else. "Huh..? What do you-"

"Wanna be my FWB instead?"

"...don't make me punch your lights out, Karma." Nagisa flatly said with a blank expression. And in return, Karma stuck his tongue out - his signature move since junior high. His expression was that of a mischievous little boy.

"Okay, I lied. Actually, I don't want that but..."

And his expression turned serious once more.

"But..?"

"I like you so be my lover. Please." Karma smoothly said afterwards, one hand tucking under Nagisa's chin so that his bewildered face was tilted towards Karma. He inhaled sharply.

Did Karma just said – 'please'?

That word startled him more tham the confession itself because he had never seen Karma using that word not once in the period of time he knew him. Nagisa was brought out of his reverie once more only to find that he had reacted a little too late to the redhead's approaches.

"Wait! K-karma...don't you dare..!"

The bold bureaucrat went ahead and kiss him directly on the lips. It wasn't Nagisa's first kiss of course but it may as well be considered as a first he had with another man! Nagisa, astonished by the unexpected turn of events, shakily covered his mouth with his hand, the lingering sensation on his lips was almost unbearable.

"You should never let your guard down when you're with me, Na-gi-sa~" Karma flashed a toothy grin, his tongue mischievously travelled across his bottom lip in a tauntingly way.

And Nagisa couldn't help but be irked with it. He felt competitive all of a sudden, like someone had just set his heart on fire.

".. Just so you know, I don't indulge in one-sided pleasure..!"

Closing his eyes, Nagisa suddenly brought his face closer to Karma's and began initiating his counter attack – Bitch-sensei's infamous French kissing technique. Forty hits under 30 seconds? Easy-peasy.

"Nagi-!"

Cutting Karma's words off, the bluenette bravely returned the kiss back, starting slow at first before he expertly slipped his tongue inside Karma's mouth, and thus began the battle of dominance between the two moving tongues. It was hot. Sloppy. Wet. Slippery. And it felt amazingly, unbelievably good. Like way better than his kisses with the bewitchingly gorgeous foreigner, Bitch-sensei or Kayano, who was now a famous actress, herself.

Thirty seconds had passed. Nagisa was the one to break their heated kiss first, licking his upper lip as he did so, his cheeks flushed pink and he was panting due to lack of oxygen. Fifty-two hits. That went pretty well if he had to say so himself.

"H..how's that..? I'm not the same naive person you used to know, no?" He pulled a smug face.

You were never naive to begin with.

Karma immediately thought, he was breathless, and stood frozen on his spot for the longest time before he too, licked some of the saliva at the corner of his mouth from dripping down his chin. His expression slowly relaxed again. Nagisa was one cunning little fox but Karma believed that he himself was capable of far more trickery and slyness.

"Wow~ That was pretty amazing. If I may request for seconds?"

"You're unbelievably shameless!" Nagisa exclaimed, tapping at Karma's smug face in dismay. "We're done... for now..."

Karma raised a questioning eyebrow at that. He was hopeful, and he wasn't going to lie about that. "For now?" He repeated in an inquisitive tone, face already beginning to light up.

"I find it rather uncomfortable if we do it here. Like Koro-sensei might be watching us on top of a pine tree or something." Nagisa was truthful for once, and the mention of the sun-skinned octopus teacher of theirs silenced Karma for a while. He too, imagined their beloved inhuman-looking teacher secretly spying on them somewhere high and undetectable with a binocular and some gravures next to him, that pervert and his weird hobbies.

"That sounded just like something he would do." Karma softly chuckled, shifting his body weight towards Nagisa. He wanted him. To have him. Now that he had finally meet the petite man once more by pure coincidence or some might call it fate, he wasn't going to let go of this golden opportunity to make Nagisa his anymore. "Then, where and when can we pick where we left off?"

"Aren't we eager?" The bluenette grinned as he separated himself from the other man and helped him up afterwards.

"Nagisa..." Karma trailed off, his tone somewhere between dejected and hopeful still.

"My apartment this afternoon for some coffee?" Nagisa finally said, innocently dusted off the imaginary dust on Karma's unwrinkled black coat, his fingers lingered on the toned chest a little longer. "I feel like catching up with you, is all." He quickly added, in order to hide his embarrassment.

Thin lips slowly curved upwards and those shining honey eyes twinkled in expectations.

"Yikes. Caffeinated drinks terrify me so." Karma pulled a disgusted face and purposely leaned closer to the bluenette before using his low and irritatingly sexy tone of voice to ask, "Don't you have anything else to offer?"

A shudder coursed through Nagisa's spine at that. He unconsciously gulped. Karma's sole existence was enough to make him nervous and his head would turn bright red.

Calm down. Don't show him any unnecessary emotions.

Directing his gaze elsewhere, Nagisa cleared his throat as he mimicked a thinking pose, the way he tilted his head slightly to the right was exactly the same as Karma last remembered seven years ago.

Cute.

"Then how about..."

The redhead's face immediately brightened up with whatever expectation he had in mind and it took every last bit of Nagisa's willpower to not blush then and there. He looked so much like the cute little puppy next door Nagisa used to saw back when he was a kid.

That face should be illegal.

"...a cup of hot chocolate with marshmallows and whip cream on top?" Nagisa managed out the few words before lightly chewing on his lower lip. His voice pitched a bit at the end out of nervousness of inviting his friend, a man, over to do...adult things.

Goddammit, that smug face of his.

"Yes, please." Karma smiled as he pronounced the sacred word 'please' yet again, his smile genuine and almost too dazzling for Nagisa's eyes to feast upon, and before anything else, he proceeded to link their fingers together as he tugged at the shorter bluenette's hand, leading him to his car at the back of the building. An impressive red Mercedes-AMG SL 65 stood out like a sore thumb in comparison to the rundown building and the deserted area.

"Wha...?" Nagisa's mouth gaped wide open and closed a few times like a goldfish. "Whose car is this again?"

"Who else if not mine?" Karma said as-a-matter-of-factly.

"Huh..." Nagisa almost scoffed in dissatisfaction.

Such was life.

"We're going to your apartment for the promised hot chocolate. But first, allow me to have a taste of you~" Karma smoothly said, shoving and topping the small and most definitely lighter man into the backseat of his car.

"HEY-oompf!" Nagisa tried to escape by pushing Karma away but before he could even do that, the redhead reacted first by inching close until the bridges of their noses came into contact, licking his lips seductively. He whispered something inaudible, only his lips were moving and afterwards proceeded to peck Nagisa on the forehead.

The words...they sounded like...

'I love you...'

Upon realising this, Nagisa flinched. His heart throbbed uncontrollably. Was he that gullible of a person before? To be swayed so easily by mere words that could hold no meaning at all?

Moreover... When the other person was Karma?

"Karma..?" Nagisa timidly looked into those neon yellow eyes and saw a rare if not raw emotion in them. The man brought his right hand to Nagisa's pinkish cheek and began stroking it, ever so gently. Could it be...? He was seriously taken aback by Karma's sudden if not out-of-place gentleness. How to react to this unexpected situation?

Chomp!

"Ow!" Nagisa whimpered in pain, his ear stung. His heart raced. That was when he felt it; anticipation.

Without a warning, the redhead had playfully bitten his left ear before lightly grazing his earlobe with those vampire-like fangs of his. "Sweet. Well then, I'm digging in~"

"K-karma..! Aah!" He moaned again when Karma started nibbling on the nape of his neck, trailing kisses down until his chest, his shirt already became undone by that time.

The front of his pants tightened soon enough and Karma began unzipping it, taking out his member and stroking it with his free hand.

"Uhh!"

The heat from Karma's warm hand flowed through the contact of their skins and the massages persisted above Nagisa's soft whimpers. "Feelin' good?" Asked Karma as he nipped on the pale collarbone, happy to get a positive response from the petite bluenette.

"...I told you, I don't do single-sided pleasure..!" Nagisa squeezed at Karma's member tighter and began pumping their cocks together. His body unconsciously rocked back and forth, in rhythm to their jacking off. Both members were now dripping wet and some of the semen flowed down between Nagisa's thighs directly to his butt crack. "A-ah, I'm close.."

"...assertive, just the way I like it." Karma shakily exhaled, slipping two fingers into Nagisa's mouth. "Suck them. Make sure they're nice and wet."

"D-hamn yhou..." Slurring his words, Nagisa aggressively went at it, twisting and gliding his tongue around Karma's slender fingers and every time they came into contact with the roof of his mouth, the bluenette unconsciously moaned. Not before long, the redhead pulled his fingers away, slipping them in his briefs, now sticky with precum.

"I'm gonna enter you now..." Karma's lubricated index finger slipped right into Nagisa's wet hole and instantly the poor bluenette shrieked in surprise.

"NO! T-take it...out...!" He was trembling, shaking like a leaf but even so, his arms desperately clinging onto the redhead who penetrated his behind without a single warning.

"Mm~ we could use some lube right now, you're tight as fuck..." Karma breathed right next to Nagisa's cherry red ear, inserting another finger, and rather than reacting to his action, the young teacher blinked furiously at Karma's vulgar language instead. "W-watch your mouth...hngh!"

"Ah, my bad, sensei~ It's such a rare sight after all. Seeing your sex face, that is."

"Sex fa-?! Hnn!" Nagisa whimpered. "W-wait..a s-sec..! What's this... I f-feel weird..!"

"Hmm? Right here?" Karma twisted his finger, finally finding that sweet spot and he stroked at Nagisa's prostate gland, and the outcome was as erotic as he had expected. Nagisa's hardened dick ejaculated, sending hot white semen everywhere and some of them landed on his cheek but Karma didn't mind at all.

"K-Karma... No.. m-more..." Panted Nagisa, his cheeks flushed deep red along with his ears, tears formed at the corners of his eyes.

Karma then licked his fingers, sticky with the bluenette's cum and Nagisa never screamed so loud in his whole life. "WHAT ARE YOU DOING-!" Pulling out a handkerchief from his pocket, he quickly wiped the semen off if Karma's face and hand. "Don't do something so unhygienic!" He reprimanded, but Karma's smile only grew wider.

"I'll wait till we get to your house so be prepared, Nagisa." Karma said as he started the engine while the bluenette hastily cleaned himself and buckled the seatbelt, throwing a 'not before I lecture you first when we get home' look to the redhead.

A sigh escaped his lips.

Akabane Karma, Nagisa concluded, was an excruciatingly unpredictable man and easily had him wrapped around his little finger, seven years ago and even now.

The end..?
