In this world, each person has one type of animal hybrid. Or what is called a half-human half-animal, as their pet.

You have one too, his name is Yuu. A fox hybrid. Or the boy with fox ears and tail that you found in the forest as a kid.

"I don't like it." Yuu grumbled to you when he heard that there would be another hybrid coming to his house. Of course he refused, if there was another hybrid, then your affection would be divided and he don't like it.

"I don't want to, I don't want to" Yuu whined once again as he rolled on the floor, demanding your decision. He was your only pet and forever your only one.
