In the heart of the mountains, a clan lives in harmony with wolves. Offspring with black locks are dubbed "Wolf," whereas those born with white hair - a rare occurrence - are referred to as "White Hart." Representing prosperity, "White Hart" children bear the obligation of wedding into the Royal Family.
Sara, a "White Hart," harbors romantic longings for Alexis, the son of the King, whom she has known since childhood. Yet, she is aware that Alexis favors his twin brother, Nara. Despite her insistence on serving as a substitute for her beloved, Sara cannot keep her feelings at bay.
A "White Hart" and "Wolf" are destined to love one individual for all eternity - this is their fate and tale.
