BTS merman Tae x any gender human reader (fluff)
based off my ‘if BTS were mer-folk’ post maknae line hyung line
bubbles, darkness, i was to far down in the depths i could feel the seaweed creeping up my ankles.
my last breath, no i can’t let it out. don’t panic, keep kicking! as much as i repeated those words in my head i saw the bubbles come from my mouth, air escaping into the ink like water. it was closing in, i can’t kick anymore! someone help! please don’t let me drown! i was sinking like an anchor my own body giving up and becoming heavy like chains. this was it? i opened my eyes, blurry, darkness. what was that? there are eyes staring at me! blue, they are beautiful. so close, thats all i can see. did angels swim?
gasping for air i clawed at my sheets. that dream again. that memory. those eyes. i moved from my bed and grabbed my robe moving out of my room and to my front door. it was raining outside but i payed no mind to the water falling out of the sky. the water i cared about was vast and i quickened my pace to the shores edge. it was the middle of the night, a full moon reflected on the surface. the smell assaulted me before the waves did, i moved my body out as far as it would go. i didn’t dare go further then i could stand with my toes grounded in the sand.
my dream. my memory. i was saved when i was a little one. the only survivor from a ship wreck. those blue eyes became my savior when i wished not to go on through out the years. as i got older and left my parents house they had left me, the one we were sailing to by the ocean i always found myself coming back. i was still afraid of the water though i had no right to be with the gift he gave me that night. i know even he would be sleeping right now, somewhere using the soft coral as a mattress and seaweed as a blanket. his friends and family around him. the ones he told me about countless times. somewhere over the years he watched me with his blue eyes grow up and i watched him look the same. my saviors name was Taehyung. Tae was a fish folk, a merman. he was the ideal fairy-tail into reality. his tail was beautiful, the color of passion, deep purple and blue. his face looked to perfect and he seemed to have no imperfections no matter how hard i looked. from the tip of his strong tail to the tips of his finned ears. i found out that i was the only adult Tae talked to. all others forgot the moment they heard his oldest friends voice. but Jin allowed me to remember him, remember them, even though i’d never seen another like Tae. startled i moved backwards as something brushed my legs. i calmed myself after seeing scales under the surface of the water the same deep purple blue i was used to. I looked behind me to spot those same blue eyes peeking out from under the water, deep brown hair with flecks of green floating around him. his mouth come up to smile at me, laughs leaving him. “humans sleep during this time y/n, well most do.” i smiled back and moved to him, my sleepwear was soaked but he welcomed my into his arms. “i’m not like most humans Tae, not when i have someone like you in my life!” he laughed again, this time i could feel it. it wasn’t the only thing i could feel. his tail was solid against my thighs between them. a habit i never grew out of it seemed. both my thighs rested above his hip fins, they treading water under me. i was so afraid of the water but i trusted Tae to keep me above the surface.
“will you let me this time?” i moved my head off his shoulder to look into his eyes. “your friends would be sleeping Tae, it would be a waste to go now.” it was an excuse and we both knew it.
that day Tae saved me was the day i became unlike any other human. he gave me the ability all sirens can give only once. a gift i was afraid to use, though he offered every time we came together. Tae couldn’t keep my tiny body above the water that night. the waves to strong and the sea to dangerous. but he didn’t give up on me either. he pressed his mouth to mine and filled my lungs with the water that gave him life. in doing so the magic in his very breath changed my way of breathing. if i really wanted to i could live under the water. finish the process and become like them. he changed me without my consent and i knew that was the reason i could never be to far from the ocean. my lungs betrayed me and wished to be filled with salty water. showers were long and later in life i had a large tub installed to truely safely test my limits, yet i was still afraid.
i didn’t fear Tae or his friends but the blackness that swallowed me once already over and over. as the years past i was running out of excuses to not go. i didn’t even truely remember why i was opposed to the idea.
“its almost sun rise y/n. how about then?” my eyes didn’t leave his. he never asked more then once at a time. my eyebrows drew together in inquiry. “Tae-” “i wont let you go y/n, not ever! it wont be painful! Namjoon hyung asked the other mers and a friends of his has a mate that used to be human!” “okay Tae.” “it takes 24 hours, thats what he thinks and i want you to meet-wait...you said yes?!” “yes Tae.” “you wont regret this!” are eyes broke contact but only because he was smiling so hard his eyes closed in joy. he hugged me and i hung on tighter then before. we waited until the sun fully rose the sky changing pinks and purples to a pure blue that seemed cloudless today but just as never ending as the water we were in. i never grew cold, Tae was far to bright, warm and happy clinging to me. he didn’t talk, i think he was afraid if he said anything more i’d change my mind. when it came time he looked to me, his rectangle smile shinning and i knew he was asking if i was ready. with his blue eyes connected to mine i took a deep breath and tightened my grip around his neck and with that we were going under.
my eyes had closed from the waves and i didn’t dare open them. when i felt my lungs begin to struggle so did i. Tae calmed me with his hands, mine trying to claw away at him and the water. my eyes opened and i saw the bubbles of my breath leaving me but i also saw those same blue eyes. all at once i stopped the thrashing and stilled. my lungs sucked in and i felt the burn. but through it all my eyes never left his. my body remembered this, it wasn’t so bad. colors behind Tae had my eyes wondering to the background. we were deep and behind Tae i met pink eyes and then green. he didn’t let me go but our grip loosened. he held my hand as my other hand met two other fish folks webbed fingers touching mine. this was his world? his friends? i couldn't understand what they were saying yet, my transformation hadn’t fully started but i knew when our eyes met again that any place with Tae was home. i had missed this, maybe i needed to listen to my lungs along with my heart this whole time. i was home.
