You are a former servant, sold off as an instructor to take care of a Beastkin! Flatter the Beastkin by having chats, gifting presents, and more. Whether or not you can take great care of her is up to you. Working as a servant of a mansion, the protagonist one day breaks a precious vase belonging to his money-hungry master—and is fired. Now in heavy debt, he must make cash as an instructor to pay off what he owes. But the one he's tasked to look after is none other than an infamously vicious Beastkin known as Urunhilda.
