The ancient northern manor is surrounded by never-ending snowstorms. One cold evening, a servant discovered a seriously injured strange girl in the snow—she had long white hair, blood-colored eyes, and non-human pointed ears, short horns, and a long tail. Driven by extreme hunger, she accidentally hurts a maid and is captured and brought back by the young heir to the estate.
The heir planned to use her as a political bargaining chip, but found that the girl who called herself "Erica" had a strange attachment to him, calling him "brother" in the ancient language. What was even more shocking was that the small bright red mole on her neck was in exactly the same position as his own mole.
As a snowstorm seals the estate, the truth gradually emerges. The girl's life experience involves the theocratic conspiracy from thousands of years ago, the tampered history books, and the ancient god that has long been stigmatized. At the same time, some strange visitors began to appear in the manor - they were all pretenders of ancient gods, silently searching for and guarding their "mother" in the darkness.
In the warmth of the hearth and the acceptance of her family, the girl slowly recovers from extreme hunger and trauma. She wanders around the manor in the form of a human or a cub, learning the warmth of language in the children's games, and feeling the satisfaction of being fed in the aroma of the kitchen. And the originally indifferent heir gradually became her real "brother" through her protection day after day.
This is a story about ice and fire, forgetting and remembering, killing gods and rebirth. When the blizzard finally stops, the truth that has been buried for thousands of years will emerge in the land of the North.
