In the memory of "three good students" Chen Zichen, the first time she met Gu Qianjin was in her senior year. It was not a good time. It was the first time she entered the military zone and was arrested. In the memory of "cold-faced Lieutenant Colonel" Gu Jinjin, she was just a freshman when she first met Chen Zichen. It was wonderful but not wonderful, because he remembered her, but she didn't. It didn't matter. She would never let her escape this time. Fortunately, the time you missed before was just to make you a better person, and you won't miss it again this time. It tells the story of Lieutenant Colonel "Ice Cube" who pursues the cute "Orange".
