In Xinhai City in 2077, happiness can be bought and sadness can be sold. Human emotions have been completely commercialized by the "Xingan Group" and turned into cold "mood capsules".
Lin Jue, a well-known emotional debt collector in the industry, works to squeeze the last bit of feeling out of those "emotionally destitute". He is mean and lazy, and derogatorily refers to high-tech emotional extractors as "soul vacuum cleaners", and firmly believes that he is already immune to all poisons and his heart is as dead as water.
Until an ordinary collection mission, he accidentally got involved in a bizarre "emotional murder case." The dead do not die physically, but their emotions are completely erased and become a living shell. The only clue at the scene was a strange and alluring "ghost emotion" that did not belong to any known product.
In order to protect himself and for the sake of his damn curiosity, Lin Jue was forced to join forces with the mysterious underground emotional tuner and stepped into the muddy waters intertwined by Xingan Group, black market brokers and resistance organizations. He discovered that what he was pursuing was not only the truth, but also the forgotten true emotions that belonged to him.
When the world sinks into a false carnival, can he, this man who sells other people's feelings, capture the final reality?
