She left him a letter and went far away. He thought she had found peace and never searched for her over the next ten years. He became the leader of the martial arts alliance and married another woman to hide his true feelings, but the one in his heart was still her. When she fell ill and died of a broken heart upon learning of his wedding, he found only her grave. His hair turned white overnight.
She was actually a princess who had forsaken riches and glory for him. But a misunderstanding turned love to hatred, and she plotted her revenge. On their wedding night, she drove her sword into his heart. He met his death with a smile.
The truth was that he had known her identity all along. He had deliberately kept his distance to spare her suffering, and fought his way to the top only to become worthy of her. A misunderstanding born of profound love ended with them separated by death, their love and hatred both coming to naught.
