Qiao Ying, the eldest daughter of the Qiao family, wakes up in a dungeon with no memory. By chance, she saves Shen Qingyu, a blind young man whose eyes are covered with white silk, and the two join forces to escape. She believes he is merely a gentle and kindhearted young nobleman fallen on hard times, trusting him wholeheartedly through one dangerous ordeal after another. Little does she know that this seemingly harmless young man is actually the fox demon villain feared by all three realms. Hiding his claws and sharp edges, he disguises himself with a gentle demeanor and stays by her side. But that fox tail he can never quite keep hidden—is it an innocent mistake or a carefully laid trap?
