Cold-Blooded, Cruel Beast Tamer X Rebellious, Unyielding Snake Beastman Boy
The heroine is a beast tamer at an auction house, hired by wealthy clients to tame the beastmen they have just purchased. She must make sure their wildness is completely erased so they won't hurt her clients.
The hero is a snake beastman bought by a wealthy noblewoman to be her bed-warming pet. His lean build led his clan to shun him, while his pale, handsome looks made him a target for beastman smugglers, who captured him and put him up for auction.
In this world, beastmen have low status.
