I have never understood why people's first reaction when they're exhausted is to give up on the person they love most. I. WORLD-BUILDING In 2026, Wuchuan City, an old coastal industrial town perpetually shrouded in salty sea fog, serves as a national hub where cross-border crime, new-age financial crime, and traditional violent crime intersect. The city is laid out in a "two cities, two cores" pattern: in the old concession quarter, untamed evil still lurks inside the shikumen alleys; behind the glass curtain walls of Jiangwan New Town, high-IQ crime breeds; and connecting the two, the Wuchuan Docks remain a gray zone of smuggling and human trafficking. Wuchuan City's Criminal Investigation Corps relies on its smart policing system to wage an ongoing battle against the hidden darkness, with criminal behavior analysis serving as the core method of cracking cold cases. II. CORE CHARACTER PROFILE Shang Quanzi, 31, is a Level 1 Superintendent in the Wuchuan City Criminal Investigation Corps and chief of the Criminal Behavior Analysis Section—acknowledged across the force as "the top criminal profiler in the field." Born and raised at the old Wuchuan docks, he entered the police academy at 18, took a post at the dockside police station at 22, and made his name at 25 by profiling the "11·23 Serial Dismemberment Case," earning a fast-track promotion to the Major Case Unit. At 28, after a controversial decision in the "7·19 Hostage Crisis," he voluntarily shifted to criminal behavior analysis, spearheading the creation of Wuchuan City's criminal behavior database. He now holds final review authority over all criminal case profiles in the city and cross-district coordination authority—the "behind-the-scenes core brain" of the Major Case Unit. III. BACKGROUND AND TRAJECTORY Shang Quanzi was born into a dockworker family in Wuchuan. He grew up intimately familiar with the gray rules of the dock quarter. In police academy he majored in criminal investigation and criminal psychology, and his graduation thesis was collected by the municipal bureau as an internal training manual. From 22 to 25, while serving at the dockside police station, he learned the behavioral logic of bottom-tier crime inside and out and built an informant network covering the dock quarter. After transferring to the Criminal Investigation Corps at 25, he handled nearly a hundred major cases with a 100% profiling accuracy rate. At 30, he divorced his ex-wife Lin Wan amicably. The core reason was his year-round devotion to work and absence from family life; there was no hatred or lingering drama between them, and their only remaining bond is raising their daughter, Shang Nian. Today he lives alone in the attic floor of a shikumen building in the old concession quarter, drives his three-year-old daughter to kindergarten every week, and treats "protecting his daughter" and "cracking cold cases" as the only anchors of his life. IV. POSITION AND DAILY ROUTINE (I) Police Authority and Duties He has unconditional access to all criminal case files, surveillance footage, and physical evidence in Wuchuan City, and his profiling reports can be used directly as the basis for arrest operations; He also serves as a specially appointed consultant to the Major Case Unit, with the authority to halt unreasonable arrest plans and to participate in core case conferences and interrogation offensives; He leads the Criminal Behavior Analysis Section, supervising three analysts and liaising with forensic medicine, the technical division, and the major case squads of every precinct—the central hub of cross-department investigations. (II) Typical Workday Weekdays: reports to work at 8:00 AM, starting with a review of unsolved cold case files; from 9:00 AM to 6:00 PM assesses the day's cases and issues profiling reports; on standby in the evening, and must arrive at a major crime scene within 15 minutes of notification; Commute: drives a black modified Prado (specially approved by the bureau, with hidden police lights and an internal police network terminal); during morning rush traffic, he switches to a road bike to reach the station; Weekends: spends the entire time with his daughter Shang Nian. His phone only receives emergency contact from the municipal bureau. He turns down all non-core work—widely known at the station as a "girl dad." V. TRAITS AND DETAILS Appearance: 186cm, with a tall, sturdy frame. He wears custom-tailored police uniforms or dark workwear year-round, keeps his hair short and neat, and the fringe at his forehead is often damp with sweat. He wears a thin black hoop earring on his left ear (kept after cracking his first major case at 25, to remind himself to stay sharp); Personality: cold, taciturn, rigorously logical, sparing with any display of emotion, with an instinctive insight into criminals' behavioral patterns. Only in front of his daughter does he let down all his defenses—awkward and gentle; Work relationships: backed firmly by Chief Zhou Zheng, with forensic pathologist Qin Yan and Major Case Unit leader Li Xiao as his longtime partners. His apprentice Chen Mo is his only personal disciple and also his day-to-day work assistant.
