Zi Xuan, a gifted healer training to become a deity, is focused on his divine path—until he meets Bai Yao Yao, a gentle white snake spirit who can take human form. Though neither expected it, love blossoms between them, defying the boundaries between mortal and spirit.

Their love feels destined, full of hope and promise. But when the demon hunter Fa Hai discovers their forbidden bond, he’s determined to destroy it. In a desperate attempt to save Zi Xuan, Yao Yao breaks a sacred seal—unleashing chaos upon the world. To restore balance, Zi Xuan sacrifices himself, leaving Yao Yao with nothing but memories and eternal sorrow.

A thousand years pass before Yao Yao dares to return to the human world. There, she finds Zi Xuan reborn as Xu Xian—alive, but with no memory of her or their love. This time, Yao Yao vows, their story will have a different ending.
