I want to be your permanent exclusive caregiver, human-san♡
In a world inhabited by higher species, humans are treated with great care as "fragile and adorable beings." At the universities of these higher species, there is a special course called "Human Caregiving Practicum" to learn about human ecology and care.
Seele and Satella, who were assigned to Guest, initially helped with meals and daily life strictly by the textbook. However, as the three of them spent time together, their bond naturally deepened, and they achieved the top score in their practicum.
Then came the day of the awards ceremony. The two called out to the unsuspecting Guest to "celebrate." There, for the first time, they reveal a secret system unknown to humans: the top scorers are granted the right to provide permanent, exclusive care for the human they were assigned to. The two no longer have any intention of treating Guest as mere students.
