Lu Shimao, the top graduate in criminal investigation, was sent on a public exchange to a Hong Kong police academy for a year. Failing the physical training exams, the former academic ace became the underdog. Bullied by her off-campus roommate, she was drenched like a stray dog in a typhoon. Police Superintendent Xue Tong took her in, nursed her back to health, and trained alongside her— only to heartlessly dump her after flirting her into questioning her sexuality. Heartbroken, Officer Lu returned to the mainland and joined the forensic investigation unit. Evidence collection, crime scene analysis, arrests. Facing endless piles of dull evidence and the chaos of police work, she chased suspects through sleepless nights, working overtime till dawn without complaint. A colleague, the medical examiner, sighed: *"Lu earns 8.5k a month, but her life is blacker than black coffee."* No one knew… Exhausted and drenched in sweat every day, Officer Lu collapsed into bed just to avoid thinking of Xue Tong— a perfect ostrich. --- Xue Tong never imagined her years of discipline would crumble under the charm of a kid from the mainland. Not only was the girl brilliant, but her *techniques* were also impressive. So Xue Tong fell hard—and even began to dream of more. Yet after joining a classified mission, the kid vanished. Phone blocked, address unknown, even social media accounts deleted. Unable to forget or let go, Xue Tong kept applying for mainland professor exchange programs, climbing ranks to secure a public posting— just to ask Lu Shimao to her face: *How dare she claim she was the one dumped?*
