Nishinoya Yū x Merman Male Reader

Seagulls squawked over head as a lone merman stayed perched on one of the many rocks that decorated the beached, all slumped into a rocky barrier to separate the deep from the shallow. His colored scales shone in the sun, having to go back down into the water to wet his gills so he could continue to watch the humans. He's been doing this for days, watching as humans of all shapes and colors came and went, splashing around in the refreshing water to get away from the hot summer sun. But that was all on the shallow side of the rocks, no one dared to go to the deep side.

He was always told to never touch one, "They are dangerous and want our scales!" his mother would say to him before he even left the coral. He's only ever heard stories of the humans' destructiveness, the fear his parents held instilled into his head. But he couldn't help but be fascinated by them; Their skin seemed to never dry up, the way they change color if they stay on the sun for too long, the pieces of things they keep on themselves, the weird objects they throw, it was all just so fascinating to him. Sometimes, he wishes he could do what they do. Humans looked like they were always having fun and he wanted to join in, maybe make a friend or two while throwing round objects at each other.

He watched as the round object he was thinking about flew over his head, bouncing off a couple rocks before landing in between them, bobbing up and down in the water. The young merman ducked into the water as a small boy made his way over the rocks, his wet, sand covered feet making a pit-patting noise as he jumped from rock to rock. The ball floated away from him as he reached for it, huffing as he back away and ran full speed to jump. He effectively belly flopped onto the round thing, rippling water everywhere as the merman saw him clinging to the object. It slipped out of his hand and shot out of the water, the human child looking at it in confusion before he started flailing his arms about.

The merman stared at him as he flailed his arms and... second pair of arms? He had no idea. He knew what was happening, but the fear of what could happen crawled its way into his mind. 'What if it's a test? What if they catch me? What if they put a hook in my mouth?!' All went through his head. He watched as the boy twisted his body around, desperately trying to swim up to the surface. The deep end was no joke. It was a big, sudden drop only a few feet away from shore. He watched as the human slowly stopped. He nervously looked around before quickly swimming up to him, grabbing him from under his armpits and dragging him to the surface. He didn't know much about humans, but he knew they needed air.

He reached the surface and carefully laid the human down on the shore, not wanting to hurt the delicate feeling flesh. He put his head to the humans chest, panicking, before making a fist with his webbed hand and using all his strength to hit down on the humans chest. The human sat up in a coughing fit, startling the merman as he backed away into the deep, the top of his head the only thing popping out of the water. He stared as the human coughed up water, holding his chest as he turned to his knees. The coughing died down as he sat back again, spotting the weirdly colored creature in the water, only a couple feet away from him. "OH MY GOD, ARE YOU A MERMAID?!" "Merman," "OH MY GOD, ARE YOU A MERMAN?!"

"Yes," He propped himself on his elbows as the human stared at him with what he thinks is disbelief, "Are you nice?!" The human got to his knees before crawling closer to him, the merman floating backwards to get away, "Dipshit, I saved you, what do you think?" "You don't have to be so mean!" "And you don't have to be so stupid!" "I'm not stupid! What's your name?" He stopped yelling as he sat down, the water washing the sand on his bottom half off. "Why would I tell you? So you can ship me off to those factories and eat me? No thanks," He dropped his head in the water, "Wait! I'm Nishinoya Yū!" He yelled as the merman's head popped back out, "Thank you for saving me, how can I repay you?"

He thought about it, "Don't tell anyone I exist." He disappeared.
