*slams table repeatedly* MYUNGJIN MERMAID AU MYUNGJIN MERMAID AU MYUNGJI-

mermaid AU instalment 4 aYo

oh my god i’m so sorry i’m taking this long 

me: i need to finish this and start drabbles (?)

also me: literally takes three years to figure out laws of physics in an AU

MJ being Sanwoo’s cousin

Hangs around Sanwoo all the time

Except when Eunwoo started going up to the surface all the time

MJ: “ok but where are you going :(”

Sanha: “don’t leave us :(”

Eunwoo: “you guys play w each other all the time anyway ????? I’m just going up to collect sea glass”

Sanha: “ur leaving me alone???? with (whispers) the old one?????”

Sanha: talk shit get hit

Sanha, rubbing his arm: “ok no but are u going up agAIn to see-”

Eunwoo, glaring at Sanha bc he’s about to expOSE EUNWOO

Sanha, faltering: “if there’s anymore sea glass left?”

MJ: “we can help you look!!!”

Eunwoo: “nO”

MJ:

MJ:

MJ, squinting at Eunwoo: “…okAyyyyy”

Cue Eunwoo going up to the surface

Cue a not-subtle Sanha grabbing onto Eunwoo’s tail and wiggling around and singing in excitement because today Rocko’s going to teach him about what he calls a “guitar”

Sanha: “is it the same as a (insert blubbery noise)”

Rocko:

Rocko:

Rocko: “uh I guess ??”

Rocko: “ok but how does stuff sound underwater how do sound waves travel do you sound the same underwater as above water how do you record music underwater do you even have recorded music”

Sanha:

Sanha: “bro”

Me: “ok you know what this is an au fuck physics”

@binsmoon: “LMAO I WAS JUST GONNA SAY”

Eunwoo laughing because his brother is so ridiculously excited

Cue a slightly subtler MJ ducking behind rocks and peeking suspiciously at Eunwoo & Sanha talking about a rock and a bin (???????)

Wtf they have plenty of rocks down there

Eunwoo’s entire ceiling is a huge slab of rock

Also they don’t exactly have trashbins but like

Why go up to the beach

To see a bin

?????????????

MJ, a poor confused bean,

Eunwoo depositing Sanha with Rocky

Sanha yelling after Eunwoo to “not do anything I wouldn’t do!!”

Rocky flushing and spluttering because wow biN WHAT

Eunwoo just laughing and waving to his brother because knowing Sanha it’s probably

“don’t eat unseasoned seaweed" 

or “don’t insult the mussels”

Not that Sanha hasn’t done that on accident before

The mussels weren’t happy

Wow do you remember when the furthest nsfw I’d go was Binu going shirtless

Shakes fist in anger because wow astroad we were all betRAYED

I DARE YOU TO DO THIS BINU >:( 

Bin can attest that if you think making out is the best thing then making out when you’re in water and virtually weightless because your boyfriend is a merman tops that 100%

Binu being pretty much in the same position they were in when Bin rescued Eunwoo from the damn fisherman’s net

Except, you know,

With less life threatening things

Eunwoo tasting like salt duh and something clear and sweet and bubbly

Bin chasing Eunwoo for another kiss whenever he pulls away

Eunwoo being soft and giggly with Bin and bumping their noses together

Eunwoo pulling away from small kisses and Binu smiling at each other

Oh my god this is just pure and chaste and happy I’m so soft

Imagine yourself in either position guaranteed heart failure personal experience my heart hurts

Bin pressing kisses to Eunwoo’s nose and forehead and palm and wrist and just being soft at his angel 

“oh mY ASDJHFKJDF” + a splash

Wait

WAIT

Bin straightens and turns his head slightly to the left

What the dang diggity dong was that

That was definitely not Sanha because Sanha’s tail is yellow

That was an alarming, non-yellow blob 

Flipping out of the water

Eunwoo squinting in the moonlight towards the ripples then disappearing underwater 

And resurfacing with another merman

Bin yelping because he wasn’t prePARED 

JUST LIKE HOW I WASN’T PREPARED TO SEE THE GOOGLE RESULTS OF HALF HUMAN HALF JELLYFISH WHAT THE FC

MJ guiltily smiling at Eunwoo 

Eunwoo staring exasperatedly at MJ before hollering for Sanha in dolphin

Sanha splashing up next to Eunwoo and beaming 

Rocky spluttering for the second time because wow he didn’t sign up to be splashed by a noodley merman 

Before getting to his feet and skipping gently over rocks in his flip flops over to where Sanha seems to be

Sanha also jerking back and pushing Rocky onto stone away from MJ because “listen he looks harmless but he’S DAN G E R OU S”

Bin still treading water before Eunwoo motions for him to get up on the rocks

MJ beaming up at Rocky and Rocky smiling politely back until he realises 

MJ has teNTACLES

Rocky, screaming highER THAN THAT ONE NOTE HE DOES IN REPLAY

Jinjin jerking awake because holy shit what the hell was that sound 

It sounded like it was

Rocky 

Coming from the beach 

Jinjin scrambling to put pants on in the dark 

Brain obviously not working because while he’s the day lifeguard Bin’s supposed to have his back during night shift 

Which means Bin should be working right now 

Jinjin blindly stuffing his feet into flip flops and tumbling out of his room into the corridor and out the building 

MJ’s face falling slightly because well 

He’s half jellyfish and he hasn’t tested his stingers on humans to see if they’re venomous or not

And as expected, Eunwoo and Sanha would rather not chance it so 

He raises his tentacles in a sort-of sad shrug and Sanha just smiles weakly

He really hates seeing MJ sad but they haven’t any other choice

i would nOT RECOMMEND GOOGLING HALF HUMAN HALF JELLYFISH THE F*RR*ES HAVE DRAWN THINGS THAT SHOULD NEVER EXIST

Eunwoo sighing and introducing Bin and Rocky 

MJ, brightening immediately: “SO THAT’S WHY YOU’VE BEEN TALKING ABOUT BINS AND ROCKS”

Bin blinking and blushing because wow 

Eunwoo talks about him?

Rocky watching his best friend flush in the bright moonlight and snorting because “you idiot of course he talks about you you’re dating”

Bin breaking out in a smile because wow Rocko’s right he and Eunwoo are dating

Rocko, squinting slightly:

Eunwoo, beaming up at Bin:

Sanha coughing because he is a pure son and doesn’T NEED TO SEE HIS BROTHER MAKING EYES AT BIN THANK YOU

Jinjin bursting onto the shore, eyes frantically searching for the scream:

Jinjin seeing Bin and Rocky sitting on some rocks and talking to three people bobbing in the water and his heart dropping a huge weight because they’re safe, his boys are safe, nobody seems hurt,

Jinjin being out of breath and having to bend over to catch his breath and Bin catching movement in the corner of his eye and seeing a smol Jinjin on the beach

Bin singing Because It’s You is my favourite thing in the world my heart is bursting >:(

Eunwoo and MJ and Sanha flipping into the sea and disappearing 

Jinjin looking up to see Bin and Rocky bobbing in the water 

Wait

WAIT 

There were 5 of them beFORE 

Jinjin going over to where Bin and Rocko are having a fabricated argument about the merits of human sacrifices 

“yo wtf there were 5 of u”

Bin and Rocky looking at Jinjin and deNYING VERY VEHEMENTLY

“5???????? what 5 haha”

“duuude maybe u should get glasses lol”

“hahaha what’s a five even”

Rocky smacking Bin to shut up 

Eunwoo & Sanha bobbing in the distance worriedly 

Because wow look another human out of nowhere they were lucky Rocky knew Bin and accepted Eunwoo and later on, Sanha 

later on because 

Rocky, casually expecting that since sanha & eunwoo were related they’d have matching tails: 

But not for Sanha’s tail to be bRIGHT FRICKING YELLOW

Rocky, scREAMING

Sanha flipping Rocky off with his tail

Eunwoo being scandalised becaUSE WOW HE DIDN’T RAISE HIS BROTHER TO BE THIS RUDE TO CUTE BOYS 

But it definitely isn’t safe and they need to be more cautious the next time because the next one to come down might not be Bin’s or Rocky’s friend 

Just as well Jinjin is then

Jinjin staring very hard at Bin’s wiggling and Rocky’s glaring 

Jinjin: “ok boys ur lying pay up”

Bin and Rocky immediately clinging to Jinjin and begging him not to freak out 

Jinjin laughing because he’s a lifeguard, for god’s sake

What the heck would make him freak out???? A mermaid??????

Pfft

Bin:

Rocko:

Wait

Bin’s and Rocko’s face just dropped 

The pit of Jinjin’s stomach also drops 

Jinjin: “You’re not serious.”

Rocky looking at Bin 

Bin looking at Rocky 

Jinjin casting a disbelieving look out at the ocean 

Jinjin seeing a stray tentacle waving from a distance 

Jinjin faints 

Sanha: “oh myg od”

Sanha: “is it because of our tails do you think?”

Eunwoo: “nah”

Eunwoo: “he probably ate something wrong”

Sanha:

Eunwoo: “of coURSE IT’S BECAUSE OF OUR TAILS U IDIOT WHAT DID U T HIN K”

MJ, wobbling around and waving his tentacles and catching sight of Jinjin: “maybe he’s a prince I should kiss him”

Eunwoo, stunned into silence for a while then cautiously suggesting he leave the kissing thing for when Bin and Rocky’s human friend is slightly more adjusted to seeing half-marine animals

MJ, squinting at the shore: “sounds fake but ok”

Rocky kneeling over Jinjin, trying to revive him and Bin waving Myungsanwoo over 

Cue Jinjin waking up with two half-dolphins and a half-jellyfish bobbing near the shore and Moonrock sitting in the sand 

Jinjin, slowly sitting up:

Jinjin:

Jinjin: “explain”

Cue Bin’s very condensed version of what happened in part 1

With Eunwoo’s clear voice supplementing whatever Bin misses 

Jinjin staring in disbelief (still) at Eunwoo 

MJ clapping with his hands and all his tentacles (soft squelchy sounds) because wow!!!!! this is the first time he’s heard it too!!!

Good job, Trash Bin!!!!

“Bin,” Sanha hisses under his breath 

Good job, Trash Bin!!!!

Bin smiling weakly & looking at Jinjin with worry 

Only to follow Jinjin’s gaze to a certain half-jellyfish 

Jinjin, softly: “holy shit”

this went on for longer than i realised adslfhasdk
