Emotions are never humanity's original sin. Pain, loneliness, anxiety, and low self-esteem are all part of the warmth of being alive. Healing does not mean eradicating negative emotions, but accepting our imperfections and embracing our true selves. Shen Xilou, a cold and rational emotion hunter, comes to terms with his own trauma and learns to love and be loved as he heals countless trapped souls. Together with Lu Zhian, whose tenderness shines through his imperfections, he confronts the fanatical ideology of an extreme "painless utopia" and ultimately protects the full range of human emotion and the warmth of everyday life.
