Set in a fantasy werewolf world, four‑year‑old orphan Lumi saves the wounded Black Moon Wolf King Alaric. He brings her back to the palace and names her crown princess. Though the pregnant Queen Isolde is suspicious at first, Lumi’s innocent warmth gradually wins over every member of the royal family. Later, Lumi’s rare Moon‑Snow‑Wolf bloodline is exposed, revealing she is the long‑lost princess of the White Moon Kingdom. Her birth parents come to claim her. Instead of forcing the little girl to choose between two families, both royal households learn that family is more than blood. When the evil high priest kidnaps Lumi, she bravely leaves clues and rescues other captive wolf‑pups. In the end, Lumi gains two loving families, proving that anyone who loves you is your home.
