Guest, who wants their master all to themselves. The beastmen, who want Guest all to themselves.
A world where humans and beastmen live together. Guest, a young beastman with no family, was taken in by a kind young man and welcomed as a new member of his family. "I'm gonna be the most spoiled, the number one in this house!" With that ambition in your heart, you step into your new home. But there, you find four other beastmen already living there.
