Sorry for the delay, ahhhhh, I really racked my brain to write this, I hope you like it :)
Just a "tool".
Being a night watchman in an aquarium wasn't exactly your dream job, but you needed money and that's what you had available to you. Walking through the dark corridors, you wouldn't imagine ending up finding a secret passage in one of the offices that would take you to a place underground that looked more like an aquarium with deep-sea creatures.
"What the hell is this all about?" You wonder, as if the answer is going to come from somewhere.
When investigating deeper into the place you were, you saw a huge tank that looked more empty. Getting closer and closer you almost gave a startled scream as a creature, a merman came out of the shadows and crashed into the part of the glass where you were looking, he looked pissed. He stared at you with a menacing aura, as if he could go through the glass of the tank at any time and put a more painful end to your life, but you remained calm, his gaze was piercing, they looked like blades that could pierce you, but you continued there thinking it could somehow calm him, maybe? You just talk but you didn't expect him to understand your language.
You looked at him again and now paying more attention, you saw that the merman had scars on both of his wrists, indicating possible torture or perhaps an attempt to escape while in handcuffs.
"I won't hurt you, I just found this place by chance." You noticed how he frowned, then seemed to understand you, he then walks away, leaving you confused, and then returns with two more mermen, one of them being quite similar to him in body and tail, but different from him, this one mernan wore a mask and had long dark hair, the other one seemed to be a little younger than the two, but still slightly similar to the first one you met.
"Brothers?" You question them, and all three of them agree at the same time. "My name is Y/n, I'm just a night guard, I found this place here by chance, what are you doing here? Have you been captured or something?"
The first one you met nods, as his supposed twin tap on the glass to get your attention, and move their hands in what you understand was sign language, he asked if you understood him, you say yes, what seemed to make him happy, then he starts talking to you in that language.
"We got stuck in the sand because of the low tide, they captured us and put us here, but they are hurting us more and more."
Oh god that made something in your heart clench, it was obvious they were just afraid of humans for the way they've been treated so far, and you wanted to help, you just didn't know how.
"Maybe there's a way for you guys to get out of here, but it could take weeks, even months...but still there might be a slim chance." You say a little confident.
Vincent puts one of his hands where your hand was and nods in response, that was your way of thanking you, you smiled back.
Looking around, you searched for some possible smaller tanks, maybe the same ones that brought them here, without success, but you knew they were somewhere, you would look for that later.
You continued to communicate with the three, the youngest one seemed to have an idea, and he pointed you up to the platform where there was the hatch that was the opening of the tank. the first to emerge had been the oldest. He leans up on his elbows as he looks at you curiously, he shows you a sharp, smug smile and then speaks to you for the first time.
"Pretty bold of ya, human..." Said the one with the scars on his wrist. You found his country accent curious and even a little amusing.
"We have to take risks at least once in our life!" Your answer makes him laugh "So... Are you really going to help us?"His blue eyes stared directly at her, and there was something mesmerizing about them, something you couldn't explain, but it felt like two unexplored deep oceans, something that seemed to make you lose yourself in your own mind."Sure." That word seemed to have come out of you, you even noticed just shaking your head trying to come back to yourself.
"Hey, what's matter?" The younger one asks, but his brother just shakes his head and replies "Nothin." You two laugh again. "By the way, what's your name? Or don't you?" You ask.
"Tch!! Don't be silly, of course we have, name is Bo, this is my twin brother Vincent." "And this is the youngest, Lester." Em follows him and points to the other who responds with a cheerful "Hi!" You guys get to know each other a little more, the brothers were a lot of fun, especially Lester who seemed to have a lot of sympathy with you. You also talked about the vague idea of how to get them out of that place, but you asked them to be patient, they listened carefully, and they seemed to agree with your plan, even though Vincent seemed a little worried about what would happen to you next, even though you assured that this was not something to think about right now.
You saw that the moment was no longer for conversation, soon your shift would be over, and you needed to go back to your post, then notifying the three mermen of your departure. They understood your emergency, just saying goodbye briefly, as you walked away and closed the entrance to that hiding place.
After you left, the smile on Lester's face was gone, he knew what Bo had done to you, and he was outraged that he'd hypnotized someone who'd been genuinely nice to them.
"You did that to her didn't you?" Lester looks at his older brother, somewhat outraged that he used you as another one of his hypnotists. The eldest just shakes his head gives a smirk to his brother "She said she would help us get out of here didn't she?We have to make sure she keeps her promise."
"But she'll be okay after that? Who guarantees what her race won't do after they find out she freed us?" Bo shrugs at Lester as he heads towards Vincent who was already snuggling down to rest "That's none of our business. What matters most to us is finding a way out of this miserable place." He turns to face his younger brother who looked worried about the human girl. "Hey, you shouldn't get attached that easy to someone, Ma always said these creatures are just cruel and inferior."
"S'she look cruel to you?" Lester says "And for God's sake, "inferior"? Really? We all know that just as there are cruel and good humans, it's the same for our species!"
Bo rolls her eyes at his brother "And you came to that conclusion in just one night?" Bo laughs "Look, I'm trying to get us out of here, and I won't let anyone ruin our chance to get our freedom." He swims to where Vincent was and gives his brother one last cold look and points his finger at him "And that goes even for you!"
That night Lester slept away from his brothers. He was mad at Bo's intentions for you, it wasn't fair to you, he really thought someone so nice didn't deserve to be manipulated like that. He sighs, deep down he had They had to agree with Bo. The three of them needed to get out of here or they would die soon, and if they had to use you as a tool, whatever, but he still promised himself he'd find a way to compensate you for your help.
