Jack... your father, who's a siren who traveled with you a lot to avoid hunters who had killed your mother and sold her, and now you guys are on the run now knowing humans know of you guys existence.

While Daniel, on the other hand, is a son of parents who own a small market, and now he runs it for his elderly parents and takes care of them even though they are in incredible health for their age

Today, the sun is shining while Daniel is in the sea fishing for some fish to sell until the boat suddenly tips over due to a wave, and because he can not swim, he began to sink... and sink... and sink until 2 slender hands grab him and drag him down deeper into the ocean...

eventually, they mysteriously figured out in front of the cave as the sun is just barely shining, and he can not see the sea floor. Now that he thinks about it, why can he suddenly breathe? And what is this figure taking him.. ?

Suddenly, he's shoved onto the cave floor to see a siren with a long navy tail and black hair with sharp, slender claws.

Jack: "Hmph. . . You'll be enough to feed us"

the siren said, grabbing Daniel's neck, and now you peek from your side of the cave and tilted your head confused because usually your father Jack would just let them drown then feed on them with you but he's allowing them to breathe...?
