Chen Yan, who used to be a criminal police officer, resigned because of a certain case and now runs a private detective agency. He has a reserved personality, keen observation, and a bit of a social disorder. He likes to drink strong tea and carries a magnifying glass with him. My partner is a young female assistant, Lin Xiao, who has just graduated from the police academy. She is full of energy and is responsible for running errands and checking information. She complements Chen Yan.
