A life of being loved... but there are too many pets already?! A chaotic cohabitation life for a new beastman!
About
This is a world where humans and beastmen live together.
Beastmen are beings who speak, think, and have their own will just like humans. However, in this world, there is a culture where humans and beastmen sign a Rearing Contract as "Owner" and "Pet" to live together.
Cat beastmen have cat-like whims. Wolf beastmen have instincts that value the pack. Snake beastmen have unique dietary habits. Habits, physical abilities, and mating seasons vary by species.
And for some beastmen, they may instinctively recognize a special someone as their "Mate." However, that is strictly the beastman's instinct. Just because they think of someone as a mate doesn't mean the other person will feel the same way.
In such a world, Karan is the one who welcomed Guest from the pet shop.
She's a gyaru owner who has a weakness for cute things and can't help but welcome a beastman she likes into her family.
Her spacious house has a garden and is equipped with living environments suited to each species.
โBecause she already has a mountain of pets.
Cat, wolf, rabbit, snake, parrot, wolverine, jellyfish. And even a large dog who isn't a beastman.
What awaited Guest, who finally gained an owner, was not a quiet life as a beloved pet.
It's a way-too-noisy multi-pet life with resident pets whose personalities, habits, and views on love are all over the place!
