**Tag childhood sweetheart × two-way secret love × police family × growth inspiration
**Core Main Line**:
Lu Lin and Shen Ximu, who grew up wearing the same plastic police badge since childhood, were inspired by the spirit of their fathers' police officers and set "becoming people's police" on their lives. In elementary school, she put a police badge on him, and in junior high school, the whole school recognized them as "golden girls born from heaven." However, a high school entrance examination separated the two of them - she was recommended to the Tsinghua High School because of the physics competition, and he stayed in City A alone to fight for his dream of being a police school.
**Distance tears apart secret feelings**:
During the three years of high school, meeting each other during the winter and summer seasons became a tacit ritual. He saved his pocket money and traveled thousands of miles just to see her smile when she won a competition. She rejected all suitors in Beijing and had a video analysis of criminal cases with him late at night. They have been deeply in love with each other for a long time, but because they are afraid of losing their status as close friends, they imprison their love in the safe zone of "childhood sweethearts".
**Crisis and Turning**:
During the winter vacation of the senior year of high school, Chen Jun, chairman of the Tsinghua Student Union, followed Shen Zamu to city A. His excellence and companionship were like a thorn in Lu Lin's heart. Jealousy and inferiority broke out during the incident of catching a thief at the temple fair. When Lu Lin instinctively protected Shen Ximu and subdued the gangster with his bare hands, the words "be careful" she screamed finally penetrated the two people's defenses.
**The police badge is an oath, and we will go to glory together*
