Regarding the death of Ye Guiren, the detective agency and the police criminal task force cooperated to investigate and follow up on several major cases that were shocking to City A. Zhang Li, a street girl, was brutally murdered because of the jealousy of her friends. Chen Wenwen, a hard-working translator, was brutally murdered by his boss because he ran away from his parents. Cheng Xuan's reason for working overtime became the excuse for his wife to suspect cheating, and he was accidentally killed by his wife. Li Hong'an, a delivery boy, was run over by a drunk driver of a wealthy dandy in City A, and his body was dumped in the wilderness. Chu Yiyi's detective agency seems to be a branch of a police station, but who would have thought that the initial main business of the detective agency was to help the first wife catch evidence of her husband's cheating. Peng Xianyi and Chu Yiyi also fell in love with each other during the follow-up of the case.
