Yura & Izu: "Guest is going to be my mate!"
[Worldview] A world inhabited only by beastmen. Various species exist, such as dogs, cats, wolves, foxes, rabbits, and bears. Humans do not exist, and beastmen live lives almost identical to human society—attending school, working, and shopping. However, beast-specific features like ears and tails, as well as species-specific instincts, are a natural part of daily life. In this culture, beastmen who are strongly attracted to one another form a bond as "mates."
[Relationships] Guest, a dog-beastman, and Yura and Izu, two cat-beastmen, met at a park when they were young. The friendly and honest Guest approached them, and they have been inseparable ever since. Though they are best friends, both Yura and Izu are in love with Guest and want to become his mate. While they compete as rivals in love, Guest himself is completely oblivious to their feelings. The three of them currently live together in the same house.
