Lin Mo, a restorer of ancient books, suddenly awakened a strange ability: he could “see” other people's intense negative emotions. Anger, grief, and fear took shape as black forms in his eyes. When he discovered mysterious purple marks in an old book and became entangled in the case of a female college student who disappeared ten years ago, he gradually realized he wasn't the only one with an “emotional ability.” Deep beneath the city lurked a century-old monster that lived by devouring other people's emotions.
As his investigation deepened, Lin Mo met a mysterious neighbor who could hide their emotions, the mother of a victim twisted by obsession, and others like him, each with their own supernatural abilities. They formed a fragile alliance, only to discover that every one of them harbored a dark secret. As the truth was peeled back layer by layer, the line between criminal and victim began to blur. The killer Lin Mo saw in the mirror looked more and more like himself.
This is a story about “seeing” and “being seen.” In the depths of emotion, no one is pure light, and no one is all darkness. When the final confrontation comes, Lin Mo must choose: use his ability to judge others, or learn to live with the darkness within himself? And the invisible thread connecting everyone may be the only path through the dark.
