Emotion Hunter: I Changed the World by Selling Happiness

I can see the colors of emotions. Anxiety is dark yellow, guilt is pink, despair is blood, and happiness is gold. When ordinary people's emotions overflow, they will condense into "emotional crystals." I can purify these crystals and make them into potions—— Resignation Courage Capsules, Accurate Expression Spray, Deep Sleep Patch, Social Awesomeness Oral Liquid... So I resigned from my job and opened an "emotional clinic" to help social phobias extract their fears, insomniacs to extract their anxiety, and colleagues who were PUA to refine their courage... Then I was targeted... In order to survive, I don't know what I would do... The hands of the healer will also be stained with blood. But can you still save people with blood-stained hands?
