Yoongi had no idea searching for shells on a beach in Busan would lead him to meeting the prettiest creature he's ever seen.

Who knew the sparkling pink tail and curious brown eyes would turn him from bitter to fond in just a couple of days? 🐚🧜🏻‍♂️✨

Yoongi looks just like in the picture. But instead of pretty white shirts and berets, he's more into oversized t-shirts and silver jewelry.

Jin also looks like in the picture but his hair is really long, past his elbows. His tail changes color depending on the water he's in.

🐚🧜🏻‍♂️✨

Spotting and picking the prettiest shells on the beach was a tedious chore that Yoongi didn't exactly want to do. But Jungkook wanted some and Yoongi is a weak man for his 12 year old brother, so here he was, walking along the shore looking for the prettiest shells.

It was quickly getting dark. He picked up some decent shells and was ready to call it a day when he spotted a movement in his peripherals. He looked that way, shrugged and was about to leave when something pink caught his attention again.

Without a second thought his feet brought him towards the rocks to investigate. The pink thing moved again and then quickly disappeared behind a boulder. He stopped halfway, thinking it was just a plastic bag.

But then the thing came back, still flapping wildly. The closer he got the more details could be seen. Like the shimmering sparkles or that it was a pretty salmon orange color with peach pink near the ends. He also noticed its fin like shape.

He put his hand on the biggest rock, stepped over a bunch of smaller rocks, looked up and the figure of a pretty man sleeping on the boulders came into view.

He quickly stopped in his tracks. His mouth opened in shock, eyes didn't know what to pay attention to.

This man had a fishtail. A very pretty one that ended above his hips, with sparkling scales that covered the whole tail, some of them coming up his hands, ribs, neck and a couple smaller ones even around the sides of his face and... his elf ears?

He was so awed by what he saw that he completely missed the fact that the man woke up and was observing him with frightful eyes, waiting for Yoongi to do anything. He only noticed something was off when the fin in front of him completely stopped moving.

Yoongi's eyes quickly traveled up to the man's face just in time to notice him backing up into the rocks behind him.

Yoongi got confused. Who is this man and why is he laying on the rocks in a full merman costume?

"Uh, hi?" he tried greeting the man but the said man let out a surprised squeak and tried getting away from Yoongi.

Yoongi observed his actions in stunned silence. Is this man trying to run from him by crawling away?

If you could even call that crawling. Maybe is was more of a slithering movement? Or maybe something in between? That's not what's important right now. The important thing is how the man was near the sea when he let out a loud yelp and quickly curled up, as if to shield himself.

Yoongi quickly walked up to him asking what happened and offered help. All the answer got was a weak push at his shin and even more whining.

"Stop, I'm trying to help." but the man just looked at him with teary eyes and kept trying to get away.

That's when Yoongi saw blood on one of the man's hands and the rock under his tail.

"Oh my God, are you okay? Did you injure yourself on the rocks?" he gasped and kneeled next to him.

The man froze in fright and one shiny tear fell down his cheek.

It quite literally fell, rolled over the rock and stopped at Yoongi's feet. He slowly brought his hand down and picked the object up to his face.

White, shiny, smooth and reflective? A bead? What? How?

"Are you a magician?" he blurted out.

The man stopped struggling and made a curious noise, "Huh?"

"Is that some kind of magic trick?" Yoongi looked up at his face "How did that bead-"

"What's a magician? A-and a magic trick?" he asked in a small voice.

Yoongi looked at his face in disbelief. His brain very conveniently decided to focus on his pretty features instead of the issue at hand.

This man is definitely the most beautiful person he's ever seen. Platinum blond hair, pink plump lips and rosy cheeks made him undeniably attractive.

While he continued to stare, the man across him started getting frustrated. His eyebrows furrowed in annoyance.

"Why are you staring?" the man called him out, his lips parted in a pout.

/Cute./

Yoongi quickly cleared his throat, "Are you injured?"

The man gasped and reached his hand down to grasp at his tail. He hissed in pain and quickly let go of the injury.

Yoongi looked down and thought 'how is this man's fake tail bleeding?'

He quickly scolded himself cause the man probably just tore the costume and it's one of his legs that got injured. That's the only logical answer.

"Take it off." Yoongi blurted out. "I'll take care of your injury."

The man blinked in confusion "Take what off?"

"The tail."

"My tail?"

"So I can see your wound."

The man appeared to be lost in thought for a couple of seconds. "And you need my legs for that?"

Yoongi sighed and nodded but what happened next wasn't exactly what he was expecting.

The man closed his eyes and murmured something to himself. And right after that his long platinum hair started gleaming... in turquoise. Rapunzel style but way less intense.

Yoongi got kinda spooked and was a second away from bolting and leaving the peculiar man alone when he heard him let out a whimper. And then another. And another. They were turning into painful grunts at thins point. And then a ripping sound could be heard.

He quickly looked down to discover the tail was ripping from the waist down. But the crack... was glowing too. The whole inside of the tail was glowing in a similar shade of turquoise that his hair was glowing in.

The vividly colored tail quickly started losing it's vibrant pink taint. Scales started falling off and fin stopped moving. It looked like the man was shedding skin and Yoongi was horrified. And pretty quickly he could spot knees poking out of the shed skin.

Then sounds of pain stopped, the glowing quickly dimmed along with them. And something unexplainable happened. The shed skin turned into something between sea foam and shiny floating bubbles. It didn't take the foam long to disappear but Yoongi was still overwhelmed.

He felt like passing out and would probably lose consciousness from the shock if the man didn't gently grab his hand and tug on it as if to request Yoongi's attention.

"How about now? Can you take a look at my wound now?"

Yoongi looked away from his face and after some internal panic (oh my God, he has legs) decided to inspect the wound. And sure enough, it was still there but didn't seem as life threatening as it first seemed to be.

Yoongi cleared his throat before speaking, "Well, nothing a couple stitches couldn't fixes."

"Stitches? What's that?"

Yoongi just met the man but already knew he was in for a wild ride.

🐚🧜‍♂️✨

Yoongi decided to take him home after a short conversation that revealed the man doesn't own any identification papers and has no relatives living nearby. He still has no idea whether it's a good decision to bring the man into his own apartment.

He just hopes it's not a part of some weird plan to rob or murder him cause that would be weird to explain to the police.

Now Yoongi is rummaging through his stuffed backpack looking for something that the man could put on himself. It's not like Yoongi get get him through the city in all his naked glory.

Finally, he finds what he calls his 'work t-shirt' and 'work shorts'. He calls them that because they're one of the most comfortable pieces of clothing he's ever owned and he always changes into them while he's at work. For inspiration and comfort of course.

He has no spare underwear on him and at first he hoped it was fine but he's not so sure anymore. The man has been denying putting anything on the last 15 minutes. He doesn't understand the concept of clothing, so why would he understand the concept of underwear?

Yoongi is beyond confused and irritated at this point. The man is being stubborn and trying to convince Yoongi to let him walk home naked.

But that's clearly /not/ happening. He doesn't want to get arrested for public indecency.

So Yoongi takes on a different approach. He tries bribing the man with dinner and it works. All he needed to do is mention the word 'fish' and the man relented. He's shocked it didn't take long but it worked so he's not going to question it.

He helps the man put his clothes on and it seems like they have another problem. The man is like a newborn deer. Or maybe horse. He can't walk on his own very well, his knees are very wobbly. He sighs and puts the man's arm around his shoulders.

And they start walking. Slowly because Yoongi is tired and the man isn't a feather either. It's not like he looked but he's taller and has pretty wide shoulders too.

In time it gets easier. The man seems to have gotten the hang of walking pretty quickly.

The weight on Yoongi's shoulders lessens. They're not looking at their feet so much anymore. Now they look more like friends walking around the city together. Well. Almost. The man is still barefoot so some people look at them with confusion. Most probably assume they're drunk.

Yoongi let out a tired sigh when they finally got into his apartment. He threw his backpack near the door, almost ripped his shoes trying to get them off and quickly laid down on the couch. He closed his eyes and tried to breathe in and out slowly.

He came to the beach to finally get some fresh air after working for three days straight. His plan was to walk around, pick up some shells, go home, order take out and sleep for at least 12 hours. He's not sure he will be able to achieve that with a stranger inside his home.

The said stranger is walking around the room cautiously, he's light on his feet so Yoongi doesn't hear him approach the couch and got startled when he felt a hand between his shoulder blades. He let out an irritated grunt and sat up.

The man was sitting on the floor looking up at Yoongi with his hands between his thighs. He was visibly tense and judging by the wandering stare, seemed kinda scared of his surroundings. Yoongi immediately felt bad for him.

"Sit next to me," the tapped the couch cushion on his left "we have to talk about some things."

"Things?" the man quickly sat down next to Yoongi and brought his legs up to his chin.

Yoongi nodded and continued, "Let's start with the basics. I'm Min Yoongi, what's your name?"

"Oh right! I'm Seokjin!" he smiled shyly and hugged his knees closer to his face.

To say Yoongi was endeared wouldn't be enough to express the warm feeling that started blooming inside his chest.

Yoongi clears his throat and asks the question that has been bothering him all this time.

"Who are you?" he blurts out "What do you do for a living, Jin?"

Jin blinks in curiousity and changes his position so he's sitting on his legs, facing Yoongi.

"You don't know?"

Yoongi snorts, "If I knew I wouldn't ask, would I? I asked if you were a magician and you had no idea what that was."

"That's cause I'm not... that." he scrunches his nose "I'm a merman! Is that really not obvious?"

Yoongi looks at him for a couple of seconds without breaking eye contact. He's trying to breathe calmly, there's no need to get agitated. The man is probably a bit crazy. And Yoongi decided to bring him to his house- oh God

"Yah! Why don't you believe me?" he put his arms on his hips.

Yoongi doesn't feel like his answer is going to satisfy Jin, so he looks breaks the eye contact and decides to look at the bookshelf in front of him.

"Humans are so dumb!" Seokjin shouts in disbelief, "I changed my form right in front of you and you still don't believe me?"

Here goes Yoongi's attempt at staying calm, "How can you expect me to believe you? Mermen don't exist Jin!"

"What do you mean we don't exist?! Humans evolved from us! We were first! How can you not believe in our existence?" Jin got so heated that his cheeks and ears were burning red at this point.

"How is that possible! Humans come from monkeys! Not from some weird nonexistent fish!"

Jin gasped "Fish? I'm not a fish! You- you're stupid!"

"Now that was a real adult response, congrats." he snickered.

"I'm a mammal! Just like you!"

Yoongi sighed, "At least you got one thing right."

Yoongi's head quickly moved in Jin's direction when he heard a hiss leave his mouth. He was about to say something funny about it when what he saw made all the need to laugh leave his whole body.

Jin had a second set of teeth. Sharp ones. Really sharp. Like a shark.

Jin got a hold of himself pretty fast and the sharp teeth quickly retracted, leaving only the normal set of teeth behind them.

They looked at each other for a long while, both shocked at what just happened.

And that was all the proof Yoongi needed to realize Jin wasn't human.

🐚🧜‍♂️✨

Jin broke the silence with a breathy chuckle. It quickly became apparent that the things he thought of as common knowledge weren't that common. But is Yoongi one of those ignorant humans or did they all just forget about the existence of merpeople and sirens?

Suddenly he felt a bit uncomfortable. Yoongi didn't seem dangerous but who knows what might be going through his mind right now? He's been awfully quiet and still for the last couple of minutes.

"Uhm, Yoongi?" Jin whispered, "I didn't mean to do that, that teeth thing, you know? I'm sorry."

But that didn't get any major reaction out of him, just a low hum. So Jin kept trying.

"A-also, I'm still bleeding?"

That finally piqued his interest. He quickly nodded and without even looking at Jin stood up from the couch and left the room.

Jin let out a shaky breath. What should he do now? Flee? His injury isn't anything major but he has nowhere to stay.

He won't be able to change back for a couple of days so he can't come back to the beach. He just realized he has to rely on Yoongi to survive when the said man came back and sat down in front of his legs. Jin blinked in confusion when Yoongi lightly tapped his leg.

"Show me your injury." he said quietly.

So Jin listened and rolled up his pants so the wound would be more visible. Yoongi cleared his throat and looked closer at his leg. His eyes were avoiding Jin's this whole time and Jin wasn't sure what to think about it.

"So how is it?" he asked hesitantly.

Yoongi just humed again and started looking through the stuff he brought with him from the other room.

"It looks fine, much better than I first thought it looked." he let out a sigh, "But I'm really tired so that's probably why."

Then he grabbed Jin's leg by the ankle and slowly poured rubbing alcohol onto the wound. Jin let out a squeal and tried ripping his leg out of Yoongi's grip. But to no avail.

"H-hey! That hurts, stop!" he pushed at Yoongi's shoulder weakly.

He was truly frightened at this point. Why's this human pouring some weird thing onto such a vulnerable place? His eyes quickly got wet with unshed tears.

But instead of replying, Yoongi leaned down and started blowing air at the cleaned skin. His thumb rubbed his ankle softly, as if to soothe the pain. So Jin stopped resisting and observed. Yoongi seemed to be confident in what he was doing. Like he'd done it regularly.

"There you go," Yoongi said in a quiet and gentle tone, "keep it stretched like this for a while, let it dry and don't get it dirty."

Seokjin nodded and looked at his lap.

Yoongi raised his head and finally tried making eye contact "When will you be leaving?"

Jin's head quickly shot up and the tears still pooling in his eyes finally started falling. Not many, just a few but it was enough to startle the older man. The weird shiny beads appeared again and he couldn hardly keep it together anymore.

Yoongi stood up quickly, "Are you crying? Why are you even crying? You can stay here for the night, don't worry. And what are those weird beads?" he pointed at the round objects falling in his couch.

Jin blinked in confusion.

"Beads? Those are pearls." He said, "don't humans make their own pearls when they cry?" he tilted his head in question.

Yoongi let out a tired breath and sat down on the couch.

"No, we don't. Our tears don't turn into valuables when we cry."

Jin hummed and gently started picking the pearls pooled on his lap and the couch around him. When he couldn't find anymore, he grabbed one of Yoongi's hands and put the gathered pearls there. Then he gently closed Yoongi's hand around the shiny orbs and lifted his head.

He smiled gratefully, his cheeks and neck got a bit red.

"These are for you, for letting me stay here for now."

Yoongi looked at him in amazement, his mouth slightly open in shock. This man's charms are gonna be the end of him.

🐚🧜🏻‍♂️✨

Yoongi left the room after that interaction. Said he would just wash his hands and put the medkit back into it's place before returning to the living room.

And he didn't lie. He just strategically omitted the part where he would splash cold water on his face to make the redness on his cheeks go away.

He patted his face dry with a towel and looked at himself in the mirror.

"Get it together Yoongi." he whispered to himself.

After a couple of deep breaths he began what he considered a walk of embarrassment to the kitchen. He opened a drawer full of leaflets from local restaurants and looked through them.

He had no idea what kind of diet Jin had but seemed to be fond of fish so a seafood restaurant it is. And just to be sure, he decided to call two places. One that served sushi with raw fish and a second one that offered his favorite cooked salmon in the menu.

He put the phone on the counter and turned around with a tired sigh.

"Yoongi?" he heard a gentle voice call him, "Is that a phone you just used?"

Yoongi nodded and leaned on the counter behind him before replying, "yes, you know what phones are?"

"Od course I do! I even had one years ago but ah," he scratched his forehead "I didn't know they aren't waterproof and it broke before I even started using it."

"So you drowned your poor phone, huh?" Yoongi laughed into his fist.

Jin huffed, "Not on purpose!"

They bickered for a while. Yoongi showed Jin his phone and laughed when he whispered, "So that's the way technology has gone after my phone's soul left this world."

And he's aware that nothing Jin said was particularly amusing but everything the merman does is quite endearing.

He just can't get enough of looking at that cute pout, the plump cheeks and curious glint in those beautiful bright eyes.

Yoongi is fucked, he just doesn't realize how badly his affection has planted it's roots yet.

Jin jumped in his seat when the doorbell rang and turned his head towards Yoongi. There was legitimate fear on his face. Yoongi explained some one is at the door and left to check.

Yoongi couldn't explain why he was so annoyed at the delivery man that was just doing his job.

He considered leaving a lower tip but it's not like the man did it intentionally so he just quickly grabbed the bag with food and slammed the door shut the moment the man confirmed Yoogni gave him the right amount of money.

"W-who was that?" he heard the moment he came back to the living room.

Yoongi quickly walked over to the couch and gave Jin the paper bag.

"It was just food delivery. Open the bag, our dinner is inside."

Jin hesitantly looked inside the bag and carefully took out two plastic food containers. Both still warm and fogged up from the heat.

"It's warm," he said with furrowed eyebrows, "are you sure the food isn't spoiled?"

"I'm sure," he nodded and opened both containers, "most human food goes through thermal processing before it lands on our plates. I'll explain later. Now try this and tell me if it's edible of if we should wait until the second delivery comes with our sushi."

After a moment of hesitation Jin relented and tried some of the cooked salmon.

He emptied his plate and was about to ask Yoongi if he can get some of his portion when the other delivery came. Jin wasn't as surprised but still seemed wary until Yoongi confirmed everything is ok.

Jin ate everything that was given to him again. Yoongi took a mental note of his adoration of sticky rice.

And they talked. They had a really long conversation that felt like minutes but actually lasted hours. It was 3 in the morning when Yoongi finally looked at the clock.

He yawned and the biggest realization of all finally hit him. Where is Jin going to sleep?

🐚🧜‍♂️✨

The sleeping arrangement wasn't hard to figure out.

Jin on the couch in the living room.
Yoongi in his bed.

Simple.

Problems appeared when Seokjin declined changing into sleepwear and refused to wear any kind of underwear the moment Yoongi suggested it.

And that's fine when it comes to pajamas but Yoongi's head aches at the thought of explaining the importance and the whole concept of clothing to Jin.

Yoongi put a pillow and a grey blanket on the couch and left after a hushed goodnight. He quickly brushed his teeth and changed into baggy sweatpants and even more baggy t-shirt.

He was out like light the moment his head touched the pillow but he woke up sooner than anticipated.

The loud ringtone of his phone woke him up and normally he would have just ignored it and went back to sleep but the chance that the one calling is Hoseok is way too high to just pretend like nothing is happening.

(The bundle of joy called Hope is kinda scary when he's angry.)

He reached out for the phone and accepted the call right away.

"Yes?" he mumbled into the phone.

But the voice he heard on the other side wasn't Hoseok. It wasn't Namjoon either.

"Hyung, I'm at the bus station. Where are you?"

Yoongi was up in an instant. He felt like somebody poured a bucket of cold water on him when the realization finally hit him.

"I'm ah- I'm on my way. I forgot my wallet so I had to come back home to get it.

A sigh can be heard from the other side. "Just say you overslept."

"What? No way. How could I oversleep and forget about my baby brother?" he said and put his phone in speaker mode so he could easily put on some jeans and a clean t-shirt.

"Stay where you are, I'll be there in twenty minutes." he quickly hung up and ran to the bathroom to splash his face with water.

He looked in the mirror and winced at his own reflection. He needs a shower. Badly.

But there's no time for that now so he grabbed a black cap and put it on his head to hide the unwashed hair. Yoongi grabbed his wallet and house keys and ran to the door to put his shoes on.

And then he ran.

He was so embarrassed for not setting up an alarm the day before. Well, that and he was also worried for his little brother. He might be a teen now but he's still a baby in his eyes so Yoongi would never forgive himself if anything happened to him.

He ran into the station all sweaty and frantically looked around the room when- "Yoongi hyung!"

Yoongi turned around and barely could keep his balance when his brother barged into him and hugged him tightly around the waist.

He let out a breath in relief and hugged him back, "Hey Jungkook. How was the travel?"

Jungkook looked up at him and smiled so hard his eyes closed and nose scrunched up. "It was good. But I'm kind of hungry so..."

"You come visit your brother for the first time and this is the first thing you have to say? Did mom stop feeding you or what?"

Jungkook giggled and got out of Yoongi's hold.

"Mom packed us some tuna kimbap and japchae so we got the lunch covered!"

🐚🧜‍♂️✨

"Go wash your hands and leave your bag in my bedroom. I'll heat up what mom gave you."

Jungkook nodded and disappeared behind the bathroom door. Yoongi went to the kitchen, washed his hands and laid out all the containers when he heard his brother let out a high pitched noise.

Then he heard rushed footsteps and Jungkook appeared at his side.

"Hyung, oh my God."

"What, did get scared or something?" he asked without looking up from what he was doing.

Jungkook hit his arm and that's when Yoongi decided to look at him.

"You... you didn't say you have a boyfriend." he whispered.

And Yoongi was glad that the stove was still turned off and his hands were empty because everything would end up on the floor with how shocked he was.

"What boyfriend? I don't-"

At that moment a confused Jin (thankfully clothed) stepped into the kitchen and Yoongi realized he wasn't just someone he dreamed about.

Seokjin looked at Yoongi with so many questions in his eyes.

Jungkook's eyebrows furrowed when he looked at Jin, "Who are you? Are you my brother's boyfriend?"

And Yoongi was ready to respond with a negative when Jin smiled wide, his eyes finally filled with understanding. And that was all Yoongi needed to get distracted for a second.

"Yes! I'm his boyfriend!"

Jungkook gasped, Seokjin laughed and Yoongi felt like he would faint any moment.

Is he still dreaming? Did he by any chance make a pact with the pretty merman by helping him? What is going on?

🐚🧜‍♂️✨

The whole situation that unfolded right in front of him seemed unreal.

Yoongi just sat on the couch and ate the cold kimbap while Jungkook and Jin sat on the floor in front of him and ate the microwaved japchae.

They met like 10 minutes ago and already seemed to be best buddies.

His baby brother and supposed boyfriend just sat there and giggled at each other's jokes.

Yoongi blinked in astonishment. He was still trying to figure out what exactly went wrong.

When Jungkook excused himself to the bathroom Yoongi grabbed the merman's arm and dragged him to the bedroom. Seokjin followed him willingly and sat on the bed while Yoongi closed the door behind them.

Yoongi took a deep breath, closed his eyes and started talking.

"Why did you tell him I'm your boyfriend?"

Jin tilted his head in confusion, "Are you not?"

"W-what even gave you the idea, I- what-" he stuttered.

When he finally opened his eyes the hurt on Jin's face was really visible. Wait, why does he look so hurt? He's the one that started this whole fiasco!

"What made you think we were boyfriends, Seokjin?" Yoongi asked in a hushed tone.

Jin sighed and looked at his feet, "I thought we were friends."

And that made Yoongi frustrated beyond belief.

"Dude, we're barealy acquaintances," he stated "so how can we be friends? Let alone boyfriends?"

"B-but we shared food! And shelter!" he yelled out. "Is that not what human friends do? Help echa other in need?"

Jin wasn't sitting anymore. He was standing, facing Yoongi with flushed cheeks and his hands on his hips.

"You need to know someone to become their friend you stupid fish! And we're not boyfriens either!" Yoongi yelled back at him.

The merman was about to say something more but after a second he quickly deflated.

"'Either'? Aren't friends and boyfriends the same thing?" he asked.

And Yoongi- oh. Oh
