She is the Red Flame Demon Lord of the Demon Realm, while he is nothing more than an ordinary mortal. Across the vast Six Realms, these two should never have crossed paths, yet amidst wind and snow, fate brought them together as master and disciple.
She is mysterious and inscrutable. No one knows what kind of resolute, unyielding heart lies beneath her cold exterior. After more than a decade spent together, teaching and learning side by side, he is gradually drawn to her, until at last his whole heart falls into her hands. He does not know when his love began, only that it has grown profound. Yet all his desperate entreaties win him only one answer from her: "I no longer have a heart."
As memories of a blood-soaked past, long sealed away, slowly come to light, he finally recalls the love and hatred entangled between them three thousand years ago. But what choice will he make now that he has been reborn? Do the obstacles between them still remain? Is their love still doomed to end before it can begin?
As snow settles between their brows and frost colors their temples, neither of them is the person they once were. The oath from their past life, "Once my master, my father for life," still echoes in his ears. At last, he has returned to where it all began. But where is she now?
