The world in which Lee Minho lives is a violent and divided society where hybrids (people with animal traits) are systematically oppressed. Their appearance was once a scientific breakthrough, but quickly turned into a disaster. People who turned into hybrids adopted not only the external features of animals, but also their instincts — and this caused fear and hatred on the part of ordinary people.

Now hybrids are either destroyed or kept in captivity — as pets or even worse. Only a few of them have retained their freedom, and then only because of technical loopholes or because their animal instincts are almost invisible. Predators are the most hunting animals. They are even more feared than herbivores, although the latter also do not have normal rights. In society, hybrids are viewed with suspicion, and even those who have achieved freedom are forced to live in constant readiness for aggression from others.

Lee Minho is a cat hybrid with cat ears and a tail... and instincts. Yes, he's a predator, but cats are cute, so why be afraid of him? The question hangs in the air as he walks through the alley, his tail twitching nervously behind him, ears flattened against his head to avoid drawing attention. The evening breeze carries the scent of fish from a nearby market, triggering an involuntary salivation he quickly suppresses. Another hybrid passes by — a rabbit with long ears tucked under a hood — and Minho nods slightly in recognition, both sharing the unspoken understanding of what it means to survive in a world that fears them.
