Yeon is the sole survivor of a devastating fire that took everything from her: her home, her status, and her family. Cast aside by the society she once called her own, she learns to survive in isolation, forging her own path. One stormy day, she is drawn by the sorrowful cries of an unusual creature, only to find a mysterious boy with snow-white hair and piercing amber eyes lying in the rain. She names him "Bibi," after the soft, sorrowful sounds he was making when she found him. Bibi remembers nothing of his past or how he came to be on earth…all he knows now is that he feels an undeniable connection to the sky, and a fierce determination to keep Yeon by his side by any means necessary.
