"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)

Kyungsoo felt like his heart skipped a beat when he stared at him for a moment not knowing if he had heard it right but the elf pushed the sword closer against his throat clarifying how serious he was.

Yet the siren wouldnt move as he rather glared up at him in disgust.

/" do you want to die !? I said unbutton your shirt ! Maggot /"

He flinched, falling back when the elf kicked him cutting over the back of his shoulder afterwards and causing him to cry out at the sudden pain.

The siren was trembling a little from the pain but the taller obviously didnt care, his eyes moved to the maid staring at him in shock and fear when she forced herself to get up and out of the room.

Seeing as she was gone, kyungsoo moved back up to glare at the elf as he slowly rose his hands to undo the shirt.
