A peerless couple, bound together through life and death, make a vow beneath the moon and journey hand in hand through the jianghu and the realm of nations, never leaving or abandoning each other. One is a princess who has wandered the jianghu, possessing breathtaking beauty and unparalleled martial arts. The other is a prince, abandoned by his country, blessed with extraordinary talent and a handsome, free-spirited nature.
Twin brothers born into a noble house are separated between the jianghu and the palace because of a choice their mother makes. Favored by fate, the elder brother becomes a noble prince who looks down upon the world. Abandoned by fate, the younger brother becomes a peerless hero who rules the jianghu.
When the brothers reunite more than twenty years later, it is on a blood-soaked battlefield, all because of a woman they both love. Which matters more, brotherly affection or romantic love? What path will he and she choose?
