In this bustling city called "Vientiane", under the shadow of the skyscrapers, there is an unknown secret market - here, the most precious human emotions are traded as commodities. The talented architect Ling Pingzhou lost all the ability to feel happiness and satisfaction overnight, and his world faded into gray. Desperate, he was introduced to a mysterious "emotional regulation clinic". The owner of the tuning agency, Li Xinyou, is a young woman with the gift of perceiving and tracing traces of emotions. She discovered that Ling Pingzhou's emotions were not suppressed, but completely "stolen". In order to regain their lost heart, the two formed an alliance and embarked on a dangerous journey to track down the "emotional thief". What they will face is not only the greedy people lurking in the darkness of the city, but also a profound torture of human nature, value and true self. When emotions can be quantified and bought and sold, what is left of a person's soul?
