Yun Juan Chu is weary of heart, weary of the world, weary of this fleeting life. Su Wanqing would bind his feelings, his love, his soul. He can reshape heaven and earth with a single hand, yet can find nowhere to call home. She can captivate all who see her with a smile, yet cannot keep him by her side for even a moment of tenderness. Grateful for a kindness once shown, he is willing to burn his life away for the humble world of everyday people. Bound by countless threads of affection, she spends her youth just to bring a smile to his face. At the crossroads of leaving and staying, with the world itself transformed, he finally understands: all the splendor of the land is worth less than her flowerlike smile, and a thousand years of history cannot rival the depth of their love. At the brink of life and death, he chooses to stay for her, breaking the shackles that bind him. Can he risk the world falling to ruin, yet not risk his own life?
