Wolf-king Arthur is cursed by the Moon Goddess: unless he finds a pure body bearing the Moon Goddess mark and completes the destined union before turning thirty, he will die.
For years, he has searched the entire country in vain—because he has always believed his fated partner must be a woman. That is, until a sudden car accident leads him to a strange young man. When the Moon Goddess mark hidden at the boy’s waist appears, Arthur finally realizes that his ten-year search has led him to a man.
To survive, Arthur uses every means to keep the young man by his side. What began as possession and resistance is destined to become a love neither can escape.
