This is a tale of love and promises that spans three lifetimes. Liu Ying, a maidservant, unknowingly saves a thousand-year-old dragon named Yuchi Longyan. In gratitude, Yuchi Longyan offers to marry her, but a misunderstanding ensues. Later, when Xia Hou Xue encounters danger, Yuchi Longyan pledges to protect her for three lifetimes to honor Liu Ying's wishes. Though he silently stands by Liu Ying in her reincarnations, it takes until her fourth life as Gu Qing Yan for her to discover his presence.
