Three years ago, Ji Huaiwan gained a strange ability after an accident in the laboratory - she could "see" the specific colors and shapes of emotions, and could even peel or transfer them through touch. This ability makes her an "emotion hunter" that the underground world is vying for. Some people offered her a reward of tens of millions to eliminate the anger of her political opponents, and some kidnapped her just to extract the "courage" emotional potion. When she was forced to peel off "fear" for a mysterious collector who was gentle on the surface but full of black thorns in his heart, she discovered that she had already been a pawn on someone else's emotional chessboard. And those stripped emotions never really disappear - they are growing crazily in the darkness of the city in another way.
