Qingyao has never seen her own reflection - there is nothing in the mirror, but she can feel every emotion around her surging like a tide. Adopted by a mysterious organization since she was a child, she was trained as an "emotional explorer", using her unique empathy ability to track and control out-of-control superpowers for the organization. However, during a failed mission, Qingyao came into contact with a buried memory fragment and discovered that she was not born shadowless, but was deprived of the right to exist. Her path of growth shifts from obedience and confusion to questioning and resistance - she must struggle between hunting and being hunted, uncovering the truth behind the organization, and finding herself. And her abilities also change on the verge of collapse: when emotions become weapons, love and fear are enough to subvert the world. Qingyao must choose at the edge of every life-threatening situation, whether to become a hunter or a prey unknown to herself?
