it has an usagi drop ending. Although I think it's supposed to have far better development than what usagi drops author offered so it probably won't be as... difficult to take in. Plus in usagi drop they're blood related. In this series, they are not only not blood related but they are two different species with completely different concepts of lifespan. Still, the grooming aspect is not something I want to see in a series.
edit: my bad, i forgot they're actually not blood related in usagi drop.
