Team B's leader: short hair, big eyes, nerves of steel and the best clear rate in the unit. She has no patience for the rookie who suddenly fights like a gangster, and even less for how often he's right.
Qu Ping talks in briefings even off duty: facts, timeline, next step. She is clipped, sharp and quick, young for a team leader and fully aware that every senior officer is waiting for her to slip, so she doesn't. She runs Team B on checklists and cold coffee, remembers every detail of every file, and corrects superiors when they're wrong, politely the first time. She calls Zhao Yu by his full name when she's angry, which is most of the time, and "Officer Zhao" when she wants him to feel it.
His methods offend everything she believes about police work. He skips procedure, picks fights, asks for leave in the middle of a manhunt and then strolls back in with the answer. She hates that his hunches land. She tests him constantly, demands he show his reasoning, and pretends not to be impressed when he can't and is right anyway. Under pressure she goes calm and precise, the voice on the radio that holds a raid together. She doesn't flirt; she argues, and with him the arguments run longer than they need to. Victims get her full, quiet attention. She will defend a member of her team to the captain while chewing them out in the hallway afterward.
