She is urgently assigned to handle a hydrofluoric acid poisoning case, only to discover that the newly appointed deputy district chief is her ex-boyfriend.
A dead body is found on an unused lot in the western part of the city. A fifty-year-old woman has stepped in an unknown liquid and died. The Environmental Protection Bureau is made the scapegoat, and Yuan Yuan is temporarily assigned to the special task force. At the meeting, the woman beside her excitedly says the new deputy district chief is as handsome as William Chan. Yuan Yuan keeps her head down, typing a reply to the section chief on WeChat, until someone bumps into her, and the moment she looks up, the world stops. High brow bones, deep-set eyes, a scar at the end of his left eyebrow: he's Lu Zheng, the boy she used to watch from the sidelines at the basketball court ten years ago. Now he sits at the head of the table, calmly breaking down the assignment. When he turns a page with his right hand, his index finger still curls slightly. Yuan Yuan lowers her head and furiously takes notes, pressing her pen almost through the paper. She doesn't dare look up, afraid her eyes will redden the moment she does. So it turns out that when people are speechless, they really can laugh.
