Lin Ye is an "overzealous" customer service person in the eyes of outsiders - in order to help customers recover losses, he dares to stay up late to check evidence and be tough with merchants. However, he is regarded as "a fool" by his colleagues because he does not know how to be "tactful". Once a customer complained that museum peripheral products were counterfeit, she came to verify the case and unexpectedly met Shen Yan, a cold-blooded museum administrator. He seems taciturn, but in fact he is thoughtful and secretly pursues bizarre cases related to "lost souls".
The jealousy of colleagues leads to stumbling blocks and opponents setting traps. Lin Ye gradually shows his talents from the "pseudo loser", but due to the clues of the case, he and Shen Yan fall into a crisis of trust. When the forgery case intersects with the mystery of "lost soul", she discovers that the hypocritical friends and the indifferent male protagonist around her all hide unknown secrets, and the truth she pursues points to a past she has never been aware of.
