When human emotions are quantified into hard currency, a sincere laugh is worth 10 joy points, and a tear of despair is worth a thousand dollars. The rich hoard "happiness" to live forever, and the poor go bankrupt due to the "depression tax." Lin Wan, a former psychiatrist, became an "emotional debt collector" due to debt.
Her mission is to harvest the emotions of the poor and feed the desires of the upper class. But between the cold data and the bloody reality, she chose to secretly build an "emotional black market" to forge emotional data for the weak to evade taxes. Until that day - in order to save the orphanage, she was forced to squeeze the "hope value" of terminally ill children on a global live broadcast. She smiled and pressed the extraction button, but backhandedly exposed the system vulnerability to the public.
In an instant, there was a run on the global emotional bank, and a tsunami of emotions swept through this alienated world. On the border between love and betrayal, she uses her clear sense to fight against the crazy order - and the truth is far more cruel than she imagined.
