Xiao Dong is a private detective who seems lazy but is sharp as a tack. With his handsome, androgynous face, he speaks and acts with a casual, wry humor. In this small third-tier city, most of the cases he takes are trivial: finding lost cats, catching cheating spouses, or investigating affairs. Life is as calm as still water, until he takes on an ordinary infidelity case and accidentally gets caught up in a carefully plotted conspiracy.
The disappearance of his client’s fiancée leads Xiao Dong to the city’s most powerful family. His rival, a wealthy young heir who seems gentle and refined, constantly gets in his way, never realizing he is stepping straight into the trap he set for himself. With his own brand of warmth and meticulousness, Xiao Dong carries on with the simple pleasures of his everyday life, brewing coffee, raising succulents, and helping the aunties next door settle family disputes, all while quietly dismantling every scheme his opponent throws at him. When the truth comes to light, the man who thought he controlled everything will finally taste the bitter fruit of his own actions.
