Tale of Under Ocean

I

Azure Kingdom, a pacific kingdom under the ocean inhabited by beautiful and legendary creatures known as mermaids. Between all those mermaids was Eren Jaeger, a merman who had strange and unique powers; he could turn into a human boy only by biting the skin over his thumb. The first time he had found out that he had such a power inside of him, he had been completely astonished and afraid. Why and how could he turn into a human? He didn't remember about anyone else of his family having such powers; so he assumed that that wasn't genetic. He tried to remember about any other mermaids of the whole kingdom, his friends, and even the royal family but no one could turn into a human being. The more he tried to understand his power the more afraid he would become. He even thought about telling this to someone but what if they tried something against him? Mermaids were known by their hatred against humans so they could try to kill him in worst case scenario. However Eren didn't think about humans as bad people because of his best friend Armin a cute little merman who loved the unknown and was always telling Eren fantastic stories about the human world that he read in old books. Eren had begun to develop a strange curiosity about humans and their world, so he decided to keep that secret only to himself and try to find out the unknown of that fantastic world on his own.

The first time he had tried out his powers, after being aware of them, he had been able to turn into a human being for only a few seconds. His whole core had trembled until the last scale of his beautiful blue green fin, and his heart had beaten so fast that he thought he would die. Nevertheless he suddenly began to doubt of his own powers, yet he had remembered the strange sensation of having two legs instead of his fin and he quickly stopped doubting. He had felt so free, so incredible that he wanted to feel in such a way again. That day he tried his power over and over again, and the last time he tried it he was able to stay as a human for 5 minutes. He even had to swim to the surface to breathe properly, since he had lost his mermaid senses.

The following days Eren just kept trying to control his powers. He bit his thumb countless times, and in each bite the time he could stay as a human being increased. After so much practicing Eren was finally able to control his strange powers; the time he could stay as a human being was now of 2 whole hours. Thus, and without even knowing it, thanks to his strange power, he would be able to find out love.

"Great, today for the first time I'll know the human world!" Eren thought feeling excited already. He swam to the surface and took a deep breath smiling from ear to ear. "Ah, this is totally different from the sea…" Just by feeling the fresh air of the human world, provided him a great feeling of satisfaction and pure bliss. He felt such freedom that he was starting to love the human world too much already. "Okay Eren, stop daydreaming and go actually explore!" The brunet swam to the seaside and once he tried to get up on his feet, he fell flat on the golden sand. He frowned in confusion and tried to get up one more time, but just like before he simply fell down. He didn't give up nonetheless. He persisted over and over again on getting up and walking but the result was always the same.

"I… I can't walk." He concluded in shock. Eren was confused; afraid; astonished. Why couldn't he walk? What would he do now? For the two next hours he couldn't return to his normal self; although he did know how to control his powers and be able to stay as a human, he didn't know how to reverse the transformation, thus he would have to inevitably wait. "But I can't wait here, I'm completely naked! For what Armin told me, humans wear clothes- AAH! What will I do now?" Eren bemoaned his unfortunate situation feeling desperate and a little sad, "Why couldn't I think about this before? Of course I can't walk; I never walked in my whole life so it's normal that I don't know how to do it. And I finally can control my power but I can't walk out there and explore this world. I feel so stupid. I wish I could be a complete human being." Eren closed his eyes softly, already giving up, when suddenly an intense deep voice sounded in his ears, bringing him back to reality.

"Hey you…?" The voice said forcing Eren to look up at the one who was talking. Upon focusing his blue green orbs on such a gorgeous and handsome male, Eren lost the ability to think and breathe. The deep grey eyes looking back at him made his heart race like crazy against his ribcage. The merman was totally, utterly enchanted and fascinated by the human.

"Y-Y-Yes?" Eren stuttered innocently; clumsily, taken aback and lightly flushed due to the other man's attractiveness. He had never seen such a perfect creature in his whole life; and his kingdom was full of beautiful and unique creatures.

"You're in my way, get out." The handsome man said so arrogantly and coldly that it made the brunet shiver in shock.

Eren frowned, clearly not expecting to hear nor see such an harsh tone of voice and attitude from the perfect human. It took him some time to register what had just happened, yet when he did so, an expected irritation started to boil within him. "What the hell's up with this man?!" Eren couldn't understand how such a charming human could be so cold and harsh towards someone he had just met. Couldn't the man see that he was not okay? No; couldn't the man see that he was completely naked?

"I-It's true Eren, you're naked! They will think that you're a pervert!" Eren blushed deeply looking away. He didn't dare to face the fascinating human in such a… abnormal situation. It was unbelievable… the first time he had come to the human world to explore, to know the unknown; something like this had to happen. Why couldn't things end up the way he wanted, for once?

"Né you; are you alright? Do you need help?" A different tone of voice asked, still Eren didn't look up. He simply remained in the same position in order not to embarrass himself even more.

"Oi Erwin…!" The gorgeous male, Eren recognized, shouted in irritation which made the merman feel even more down and ashamed.

"He can be hurt Levi. Besides he's naked, probably someone stole his clothes." The other man said, and gently bent down with an extended hand towards the brunet. The man, Erwin, asked softly one more time, "Do you want to come with us?"

I wonder what Eren will answer haha (it's pretty obvious I think ^^'')
