The following is a list of characters from Every Move You Make, a police procedural television drama produced by TVB.

Main characters CID unit members Linus Yiu Bowie Lam portrays Linus Yiu Hok-sum (姚學琛), the unit's Senior Inspector. He studied microexpressions and applied psychology at an unspecified university in the United States for half a year before returning to Hong Kong as West Kowloon Police Department's new CID senior inspector. His addition to the unit sparks mixed reactions from the team members, especially Chow Fun, who disapproves his methods of investigation, slamming them as ridiculous methods. Hok-sum, however, does not seem to mind Chow Fun's obvious lack of respect and continues to peacefully and productively work with the unit members. He quickly befriends Ma-dam, who later becomes his love interest.

Phoenix Yip Kristal Tin portrays Phoenix Yip Chin-ting (葉展婷), nicknamed Ma-dam, the unit's Station Sergeant. Ma-dam is known for being the caretaker and nanny of the unit, thus members of the unit (as well as the rest of the police department) gave her the nickname "Ma-dam", with the "ma" representing "mom". Throughout the drama, the story depicts her going through a divorce. Her husband, Raymond, files for divorce due to irreconcilable differences, and applies for full custody of their son, Jacky.

Trevor Ho Bosco Wong portrays Trevor Ho Lai-yin (何禮賢), nicknamed Chow Fun, the unit's Sergeant. He initially disapproves of Hok-sum's methods of using microexpression interpretation and other observation skills to investigate cases, but later finds these skills useful after he begins dating Hok-sum's younger half-sister, Perlie.

Mak Wing-hei Lai Lok-yi portrays Mak Wing-hei (麥永希), known as Hei, is the jokester cop of the unit. He vocally expresses his love for rich women, and consistently bickers with Fly, his partner-in-crime. He later realizes his feelings for Fly after he breaks up with his rich celebrity girlfriend.

Wu Hau-ying Lorretta Chow portrays Wu Hau-ying (胡巧瑩), nicknamed Fly. She develops a one-sided crush on Hei ever since she joined the CID unit and became Hei's partner-in-crime. To hide her feelings, she constantly bickers with Hei. Hok-sum and Ma-dam notices her comfortable body language around Hei, and they decide to help with her relationship with Hei.

Kan Ho-ming Jack Hui portrays Kan Ho-ming (簡浩明), known as Ming, is the hard-working cop of the unit. He is impressed with Hok-sum's intelligence and talent, and is always opened to learning his skills.
