An He, the strongest psychic of the apocalypse, transmigrates to a world of beastmen after dying alongside the Zombie King.
The beastmen in this otherworld have something wrong with their brains.
The stronger they are, the more likely they are to go berserk, and the only option is to send them to an abandoned planet to await death.
One day, a young man with black hair and black eyes arrives on the abandoned planet and opens a shop there.
Shop name: Fixing Cats and Dogs.
Main business: Fixing brains, fixing broken brains, fixing the broken brains of fluffy beastmen.
An He: Great, fluffy ones! So many fluffy ones!
The beastmen: Great, he can fix us! We're saved!
Doctor An He: What? You can't afford the fee?
Doctor An He smiles: Then sell yourself to me.
And so the barefoot doctor An He acquires a whole group of fluffy companions.
As the first fluffy one to sell himself to An He, Chris isn't content with being an employee at the shop. He wants to rise through the ranks. He wants to be the boss's wife!
Chris, the eighth prince of the beastman royal family, chooses self-exile to an abandoned planet just as he is about to go berserk.
Here, he finds a new direction in life: becoming the partner of that unscrupulous doctor.
An He is the bottom, Chris is the top.
Theme: Even in another world, you have to work hard to live your life.
