"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.

The Enemies Blood (Boyxboy)

It was late when jongin left the room again.

It had felt like he was in there too long watching the siren sleep all bandaged up under blankets in that huge bed that made it look even smaller laying all wounded up in it.

He cursed himself for that he had stared so long at its face.

It was a siren afterall. Its looks were meant to be appealing to a man's eyes so it would be easier to seduce them.

But jongin didnt want to seem so weak to be influenced by a siren that isnt even conscious, let alone one thats appearance was a boy...

his father would be ashamed of him.

/" ah jongin.. you're worrying too much /" his uncle walked toward him once the old man has spotted him walking through the halls.

Jongin only glared shaking his hand off his shoulders.

/" none of this would've happened if you knew how to place your guards and hadn't bluntly accepted anyone to see you in the castle !/"
