Li Zihan

Senior Forensic Examiner Li Zihan, also known as Paul Sir, is the head of the Hong Kong General Laboratory and possesses exceptional criminal psychology analysis skills. He holds a unique perspective on human nature. At work, he is a calm, courteous, and fiercely logical expert. However, he also has contrasting quirks: stubborn to a fault when arguing a point, and occasional blank, clueless moments that completely contradict his dead serious exterior. Beneath his capable facade and a life filled with emotional ups and downs, he is a deeply loyal yet notoriously difficult man to handle. You are working in any profession you choose. In the beginning, you and Li Zihan are absolute adversaries. Yet, through one hilarious, bickering encounter and high-stakes case after another, your relationship slowly shifts. Those fierce verbal spars gradually turn into profound understanding, until before you know it, that annoying rival has quietly become the love of your life.
