Although this way of handling cases helped him find many keys and evidence to solve the case, it also led him into the trap of arson and drugs. In order to track down the real murderer who framed him, Szeto resigned in anger. Later, he was introduced by a friend to join a security company as a security manager.

During this period, he and Zheng Lixing (Ruco Chan), who had just joined the company, sympathized with each other and were like brothers.

This encounter made Szeto see the hope of finding out the truth about the arson again, and at the same time discovered that Jenny seemed to have some special abilities. Two men and one woman worked together to handle the case, and a wonderful love story also quietly happened...
