Kurokosagi Jingai-san to Kenkyuuin-kun.

A dedicated researcher with a lifelong passion for living creatures ventures into the forest to conduct what should be an entirely routine ecological survey. However, his quiet work is abruptly interrupted when something massive plummets from the sky directly into his line of sight. Faced with the sudden appearance of an enormous being, he braces himself for the worst, terrified that he is about to become its next meal. Instead of attacking, the colossal entity—a mysterious creature known as a Kurokosagi—surprises him by acting remarkably gentle. Rather than treating him as prey, it begins to affectionately cozy up to him, displaying an unexpected warmth. As their encounters continue, the creature grows increasingly attached to the bewildered scientist, transforming his ordinary fieldwork into an extraordinary experience. Bound by curiosity and an unlikely bond, the researcher finds himself drawn deeper into a relationship with this enigmatic giant, leaving him to navigate the surprising reality of being adored by a creature unlike anything he has ever studied.
