(See the end of the work for more notes.)

Work Text:

Shin happily slurps the free cup noddle snack he was given by Sakamoto behind the counter , waiting for customers to come .

It was Sunday and supposedly he shouldn't be at work but this Sunday he didn't mind because, Sakamoto had planned a family bonding and shin was free anyway.

His feet dangles on air, hands on his cup noodles busy slurping while his eyes carefully runs on the paper placed on the table counter, which was the product's stock list inside that were needed to be restocked soon.

Munching as he puts it in mind before placing his cup on the counter and that's when he chokes.

And that wasn't because he was clumsy, it was the fault of a certain dark haired algae popping out of nowhere like a damn ghost, Shin would've gone after his throat if only he wasn't choking at the moment. Though he doubts he can even land a critical hit on this walking menace.

" Whahahahahah!" The other laughs tho he took pity and handed Shin a bottle of water from who-knows-where while Patting his back.

Shin was very glad that Lu wasn't present at the moment because she'd definitely laugh the hell out of her and since he prefers being alone,  it gives him peaceful and serene surrounding , though now all his ' good ' mood was washed away completely by the calamity called ' Nagumo Yoichi '

No way, he'd actually rather deal with Lu than this black algae!

Shin curses Nagumo in his mind and slaps the hand on his back , coughing the rest of the water bits until his breath returns to normal, " Sakamoto-san is out, he won't be coming back until evening. "

" Aw, what makes you think I'm looking for him? Did you peek in my , hmm~? " Nagumo grins his eyes turning crescent, making him look like a lively and chatty brat if not for his deep obsidian eyes like abyss .

[ I can't even read anything in your damn mind!] Shin inwardly rolls his eyes at the six feet tall man before shooting him a uninterested glance, " Then, where's the stuff you're gonna buy, so I can scan it. " [ hurry up so I can have my peace back, prick!]

Fighting wasn't allowed inside Sakamoto's store, shin can only swallow the anger back and cleans up the table waiting.

However, Nagumo was empty handed swaying his hands on the air showing him, " Nothing."

Unable to take it , Shin finally snaps and slams his palm on the counter leaning towards the grinning Nagumo ," Then why hell are you here!? "

Nagumo let's out another trail of laughter , instead of Responding shin was greeted—for the first time, by the flashback in Nagumo's mind.

[ ' I'll leave shin to you for a while .'

Then Sakamoto's appearance left the black canvas of the black haired male's mind .]

" So...! I'm here to help." Cheerfully said buy Nagumo, an announcement that doesn't accept any form rejection and objection.

[ Huh.. that's pretty unusual of Sakamoto-san asking help .. maybe there's another group of  assassins hunting Sakamoto-san!?] Shin sighs and threw the trash away before going around the counter where Nagumo stood tall.

[ Ugh this guy is so tall] shin wonders if he could grow this tall in future , he has to tilt his head to have a full view of Nagumo's irritatingly smiley face, " Then help me get the stocks in the storeroom ,but— before that , you can't work like that , " shin walks away to the small locker far end across the inner store, rummaging for a while and returns with a green apron in hand, it has a tag name ' shin ' on it.

He had spare one whenever the other is in laundry so he'll lend them for now .

Once he turned around Nagumo already stripped out his large coffee brown coat and rolls his sleeve.... Shin curses in his mind , envy, jealousy and HATE.

This guy looks good on everything, almost effortlessly, " here, put that on. " He smacks the apron on Nagumo's chest. [ This guy is irritating but frickin handsome . ]

Given by Nagumo's body structure compared to Shin's, the apron can't be tied at the back so they left it as it is then headed to the storeroom to get what they needed, afterwards shin instructed Nagumo to take out the trash and the other dutifully obeys. Even humming.

Huh, weird. Even so Shin didn't drop his guard , Incase that black algae starts doing funny business.  Shin starts to restock the products in shelves until Nagumo came back like bee next to him attached.

Without a word shin hands him the job as a customer walks in, he goes straight in the counter.

" Thank you for coming. "

Ting. The door closes leaving the store eerily quite, shin sighs.

" Why do you have to be so tense ." Nagumo's striking wondering voice sounded next to his ear,  getting him spooked out and causing him to fall off his seat .

"AAAA-! "

The culprit merely looks at him innocently with a gooey smile.

" Can you appear normally!? " , a response quickly came , happily, " can't do. That won't be fun at all , right~ "

Shin accusingly points at him and gets up to dust off his pants , " and , it's because of you! No way you're not gonna behave all day!" [ Not to a still hitman like you! ] And even though shin is a ex-hitman himself he can't predict this guy at all. It makes him endlessly frustrated! , " Don't you have anything else to do?" [ Get back to your damn work!]

Hand in chin ," hmm"  , Nagumo wonders for a bit. , " nope . I got day off. "

" Huh?" [ What do you mean day off? I never had any day off back in my Hitman days!] " You got day off?" Unbelievable!

"Yep! " The ' p ' was punctuated , " I decided to take one. "

Huh!? There's no day off after all!! Shin's eyebrow started twitching , " You should focus on your work, and don't bring unnecessary trouble at Sakamoto-san's store. " Shin's eyes wanders off to the clock.

Nagumo shrugged, " Don't worry, I'm on day off , I'm here to help , really. "

He sounded serious so Shin believed him ," Yeah , yeah, alright then. " for the time being and took him for lunch on the second floor, in his place.

" Eh, I didn't know you can cook shin. " With a pair of chopsticks picking up perfectly golden fried shrimp , Nagumo mouths it and munches. The rich mixed ingredients in the fried shrimp immediately spreads in his mouth. He couldn't help but let out a delightful hum as he savors the dish.

Two pink dots of flush takes place on either of shin's cheeks , he stuffs himself with mouthful of rice insisting to ignore the bubbly feeling forming inside his belly .

[ Is this what they call 'butterfly in stomach'!?]

" you'll make a good housewife." Nagumo said before munching another piece, catching Shin off guard the latter chokes on his food for the second time of the day.

Shin deeply regrets falling for the black algae's innocent trap and being kind enough to share lunch with the other to knowing he's damn rich and can get himself anything outside. [ And what the hell ' housewife!? I'm a male and a ex-hitman!]

After their lunch shin heads back first to the store while Nagumo did the dishes, as he volunteered.

Shin only shrugs ,[ not like I asked him , he volunteered anyway. ]

Seconds later the bells in the door rang, indicating a customer arrived, Shin puts a bright sunny smile towards the door's way, " Wel—" come ... The words died in his mouth as Shin reflexively grab a hidden knife under the computer of counter, automatically raising to a defensive stance , knife slanted over his front.

Snarling to the new comer in all seriousness, " What are you doing here?" [ Is he after Sakamoto-san? Heh! Too bad , boss isn't here!]

" Huh?" The dark haired male glances at shin, under his eyes in right with two eye catching moles and one in his right under eye, lazily blinking and turns away quickly to the shelves of cup noodles, muttering to himself, though audible enough for Shin to hear, " Obviously buying goods. Don't worry I have no intention of dividing my attention for other work. That was just a side gig. "

Seeing that Nastuki really did pick couple of items to scan, Shin's shoulder drops in relief taking account of the stuff,  even so he doesn't fully trust him just like Nagumo and tries to read his mind ....

It shocks him to know , he can't read Nastuki's mind at all! Shin stares at Nastuki utterly speechless, he still have his ability... right..?

Taking the plastic bag , Nastuki didn't hurriedly go away instead he opened a popsicle ice cream he bought and bit on it leaving shin more speechless, " Hey! What are you—"

" You tried to read my mind , didn't you?"  Nastuki says and leans on the counter table as he devours his popsicle ice cream unhurriedly and nonchalantly. His left unoccupied hand points on his left ear that has something black earpods on. " Guess it's successful. "

In a beat Shin understands it, Nastuki Seba was a craftsman, how can he forget it? One of his successful invention is his invincibility coat and Shin eyes the thing on his ear, that's something telepath barrier?  , " Heh, that's interesting, you made that just for me? I'm honored. " And it hits him , [ did this guy came here just to test it!?]

" Mn, " he bags the stick and leans on his back , " guess so. " Still, Nastuki made no attempt of leaving that eventually made Shin question him but was interrupted by Nagumo's happy voice and quiet footsteps, " Oh~? A acquaintance of yours, Shin?"

The two turned their heads synchronically to the new comer, Nagumo still wearing the apron that belongs to Shin while wiping his hands dry. He takes a the slot next to Shin behind the counter, eyeing the man. Taking notice of the moles on his face, " Oh  you got three moles, are those real?" Nagumo points at it.

Smacking Nagumo's hand away, " Don't do that you're being rude to the customer. " Shin turns up Natsuki, " Thank you for buying at Sakamoto's. " With a 'Now hurry up and go!' look on his face, he forced a smile.

Lasting couple of seconds, til he could feel his lips grow stiff.

" ....  "

Puff, unbelievably but Natsuki puffs a lazy air akin to a pout, " Heh... That's rude, you left me that day once I was unconscious. That's pretty harsh for someone as my first. "

Huh? The hell does this dude mean, " WHAT are you saying- do you expect me to drag you back to your home?" Either it was Nagumo or Natsuki, both was the worst people Shin could deal of.

Nagumo turned to Shin wide-eyed, dramatically gaping, " Shin-kun..you -you're cheating on me?"

" No, Shin, you cheated on me..?" Natsuki added , not least interested in his own plot, but indulging.

Being forced to a corner by the two menace , Shin smacks their heads for good , " Shut up! Don't throw dirt at me , and you -! " He Points at Natsuki ," Don't make it sound weird! I don't give special treatments to my enemy! "

Rubbing the spot where the blonde smacked him, Natsuki apathetically complains ," Heh.. that's unfair why aren't you scolding him? Ah, you're bias. " He shots Nagumo a look, the latter was obediently waiting for Shin's verdict.

Shin freezes momentarily looking at Nagumo's docile and puppy eyes , " .... "

They stared at each other for seconds then shin says , " You get back to work. "

Watching the two in sidelines, Natsuki wonders if something is between the two...

" HELL NONE!"

Natsuki was startled to hear Shin yell at him slightly flushed pink, [ oh crap ] he forgot that Shin can read his mind , he pulls up his hoodie, " See you next time ." then he grabs his purchase making a quick exit as he went invisible.

' Thud'

Natsuki went visible again as the door open and sped walk out going invisible.

... Is he sick? Shin brushes it off , finally just an hour and half more before Sakamoto and his family returns, then his shift's over. He scans the place searching for the certain someone,

[ Huh? Where did Nagumo go?]

The store was left quietly, deserted, and Shin travelled every aisle, yet he didn't find the man, [ did he left? ] He thinks and checks the backroom, storage room, even bathroom , there's no Nagumo, then he tries to call, " Nagumo? "

....

Silence.

So he already went away? Well, he shrugs [ Knew it he wouldn't last half day.]

He turns to another aisle then his vision goes black. Had he gone blind..? Wait no, he hears a deep laugh from above his head , hands covering his eyes, " Guess who is it! "

An irked mark popped on Shin's head, unhesitatingly sending a roundhouse kick but was skillfully dodged by Nagumo, he almost hit the fridge, " You rat... "

" It's me~! " Nagumo holds his hands harmlessly on air, " that's bad, what if you hit my face? I'm telling Sakamoto-kun to deduct your salary for my medication. "

Huh!? Shin's eyebrows twitched, " Well I hope it did hit you. Stop messing around. " [ Annoying prick just go home already! ].

Fixing his clothes Shin was about to walk away but Nagumo caught his wrist and yanked him back, pressing against the fridge basically towering the trapped blonde , " What a bad boy, Didn't Sakamoto-kun teach you to get along with your coworkers?" His deep big black eyes stared at Shin, almost sucking him into hypnosis.

" I— Nagumo knock it off, get back to work! " Shin feels his face heating up being stared like A piece of art exhibited in a museum, those obsidian prying eyes felt like stripping him naked, causing him to slightly quiver on the thought , Nagumo tilts his head on side thinking, " hmmm.."

" In one condition, "  He leans further, closing the gap as Shin's head was glued on the Fridge, " Kiss me ." His hand traces the blonde's cheek down to his sharp jaw, " Then I'll behave ."

Under Nagumo's unrelenting scrutiny, it was impossible to look away instead Shin swallows hard, his gaze falling on Nagumo's thin, enchanting lips that was curling to a knowing smirk, " Well?"

That sounded almost like a purr , Shin's cheeks flushed deeper as if the blood's leaking out of his skin, he forces his eyes to look anywhere but Nagumo, " .. Mark your words. "

The whisper  response had Nagumo froze for a second then his coy grin widens , " Then go ahead, I'm waiting ." His eyes glints into something dangerous mirth .

Shin was like a rabbit, Always attracting danger. And the most Dangerous danger he got tangled up to, was the person before him, A Order member and was the menace among the rest. Even though Nagumo was already bending forward Shin still tipped his toes, softy pressing his lips against the latter's.

He felt like a  shy highschool girl having his first kiss, it cringes him , lasting a couple of seconds before he pulled away , unsurely. His bravery made Nagumo's heart itch in anticipation, Shin sighs thinking that kissing someone on your own accord was way harder than being a hitman.

Before he can completely pull away, his chin was tilted up meeting a menacing smile, he heard Nagumo speak in his mind, [ " that's not a kiss ."] Then their lips crashed again, under Nagumo's hold, there was different, far different from Shin's cute and bashful chaste kiss.

Nagumo's kiss was spicy, he nips and sucks on Shin's lips like it was candy, [ sweet] he comments in his mind—   wet, his tongue slips inside, licking every angle and corner before intertwining with Shin's, fervent and tyrannical.

How was Nagumo expert on that?

Thinking further got Shin dizzy as the kiss drags every breath out of him, his hand was now clinging on the taller male, he earns few hums as if in encouragement, saliva slipping in the corner of his mouth.

They shouldn't be doing that .. But a part of him evilly wants to keep going for it, Nagumo's hand wraps on his hips like a possessive belt , he weakly grips on Nagumo's shoulder, oh .. his eyelids feel heavy, maybe he'll pass out.

Much to Nagumo's hunger, he wouldn't want to let go yet, he does. Licking his own lips while watching Shin struggle to catch his breath, " That's what you call a kiss ,babe. " He leans on the crook of Shin's neck, inhaling his scent .

How badly he wants that Scent to embed on his pillows, sheets and bed, he plants small kisses underside of Shin's ear, neck, jaw , and there was his hands on Nagumo's chest, trying to push him away  ," ..h.. you said just kiss.. asshole. "

Shin wipes his mouth with the back of his hand , panting heavily,  " but you didn't do it right, Shin.  So .." Nagumo beams and Shin feels his eyes play tricks on him, he sees Nagumo shine sunnily, " I changed my mind. "

Honestly , Shin doesn't know why he lets Nagumo screw him all the time,  he was irresistible, a damn fever that won't leave him alone,  his finger hovers on Shin's plump lips then slowing it sinks inside, Shin doesn't resist and bravely meets the latter's gaze.

One then two finger, playing inside Shin's mouth, catching his tongue in between and forces his mouth to open, " What a cute tongue, What can that do?" Nagumo's look was dark, but different than the dark look he gives when in the battlefield.

Shin feels like he wants and needs Nagumo's praise, it doesn't matter how but he's eager to hear that , he holds Nagumo by wrist steadying the hand before proceeding  to lick the finger— he earns a surprised gasp that made him confident —, he closes his eyes not wanting to chicken out when he's halfway into it and continues to suck on the long heavy fingers intruding his mouth, it tastes surprising thick leaving some flavor in his tongue, he feels the hand tremble then he gives it a final suck, " heh..  How talented, maybe it can swallow something else too? " Nagumo forces Shin's his lips to part again , the blond's eyes cracking open.

However Shin welcomes his fingers to sink deeper, tears threatening to fall but he doesn't choke on the fingers, until the knuckles grazes on his teeth. Seeming to be satisfied, Nagumo pulled his hand inch away against his face, still smiling then Shin coughs lightly.

Oh my god, the mess he did , Nagumo's entire palm was sticking wet down his wrist, he immediately let go of it as if he was burned and slowly meet Nagumo's eyes, there was storm in it. He heard him loud and clear, his eyes widening and legs giving out on the thoughts inside Nagumo's mind,

[ A image of Shin's erotic look while sucking his fingers, ' that's a lot of saliva,' I want to help you swallow them, different uncensored images flashes of Shin panting, skin pinkish beneath his own body, mouth parted as if begging for a kiss—]

" Oop, " Nagumo darkly but cheerfully interrupts , supporting Shin's limp body , " whaddya see~? What' a bad boy, " he whispers on Shin's sensitive ear, " That's intruding of privacy, very baaaad . "

Shin can't reply , he doesn't know what to say maybe he was too stunned by everything,[ was this guy' serious? Or messing with him again?] his eyelashes drops, he can barely hear what Nagumo is saying and blacks out completely.

Notes:

So should I have give them a proper one night stand?
