"The little mermaid inspired Kaisoo ff"
Except KS is not an innocent defenseless mermaid. And theres a lot of "racism".

Jongin thought being a prince was annoying, facing responsablity was something he'd avoid. Therefore he turned away from the truth and he ran away from himself.

But He hadnt known to be destined for something bigger. 
He hadnt known he had the power to change the horrors of the ongoing war, To be the hope of his suffering people. 

Now that a siren, the most hated species and the enemy to humans had saved his life and uncovered things about the war aswell as their past as they find out just how important their story was to history.

He hadn't expected to find a liking to it's feisty and strong spirit, its stubbornness and bold tongue, speaking out things to him no one has dared to before. 
Things he needed to hear.

He didnt know that falling for the enemie was the best thing that could've happened to him.
When the change of the world had started with a monster saving another.

His whole body was aching with every movement such as breathing but mostly his chest felt like it was burning up. As if the elf still held the torch pressed to his chest.

It made him grunt and grimace as he tried to feel around himself, pushing himself up to lean further against whatever he was laying.

He hesitated when he felt the water around him reaching up to his ribs. Taking uneven breath in irritation he frowned hard blinking to finally find himself in a bathtub. His breathing pace increased in shock as he stared onto his tail hanging over the edge of the bathub shimmering in the light but the scales had already been falling off mostly, the more he moved the more fell off .
