As childhood sweethearts, Jiang Qiyun and Yu Guiwan grew up together in a police family compound. One was lively and carefree, the other quiet and introverted. Despite their vastly different personalities, they became the best of friends. Before their budding adolescent feelings could be written into poetry, both suffered a major life upheaval: their fathers, bothXing Jing, died in the line of duty while jointly investigating a serial murder case. This tragedy led to a divergence in their life choices. Jiang Qiyun, who had always admired her father, became even more determined to be a fearless criminal police officer, upholding the law and justice in her heart. Unable to change Jiang Qiyun's mind, Yu Guiwan eventually went abroad to study, and the two lost contact for a full ten years. Over that decade, Jiang Qiyun, working on the front lines of major cases, became an outstanding criminal police officer. She thought ten years would be enough to forget the faint,Meng Long stirrings of her youth. However, when the girl from her memories reappeared before her as a woman, the memory of that youthful kiss suddenly became vivid and clear. But things were different: the once quiet and shy Yu Guiwan now appeared beautiful, elegant, and poised, able to offer a gentle smile to anyone. Even more different was that the person who had once most opposed her becoming a police officer had now joined the city bureau as a newly hired criminal profiler. Jiang Qiyun stared at Yu Guiwan, who was chatting and smiling, radiating charm in every gesture, and said expressionlessly, "Long time no see." The other woman, in front of the entire police force, intimately took her arm and leaned close to her ear, whispering affectionately, "A Yun, I've missed you so much." A tsundere criminal police officer and a gentle profiler.
