At Qinchuan University's campus music festival party, Zhang Yang was tinkering with the sound equipment backstage. As the "technical stream" of the Cyber Security College, he had to ensure that the performance went smoothly. During the rehearsal test, he accidentally bumped into Xu Mo holding a guitar and debugging equipment. In high school, they were classmates in the biology competition class, and the undercurrent of youth quietly surged in the night when they were writing questions side by side. Xu Mo transferred to another school due to unstable grades, and Zhang Yang wrote an unsent letter in front of an empty desk. Three years later, Zhang Yang became a "hacker student" at the School of Cyber Security, while Xu Mo was studying gene editing projects in the biomedical engineering laboratory. In the narrow corridor backstage at the music festival, Xu Mo's string suddenly broke. When Zhang Yang handed over the spare string, he joked: "In the last biological experiment, the alcohol lamp you used to soak the onion skin went out before me." Xu Mo was stunned and rolled his eyes: "Your physics competition answer sheets were folded into paper airplanes." The spotlight on the stage came on, and Zhang Yang looked at Xu Mo quietly with admiration, as if time had returned to high school. After the show, Zhang Yang and Xu Mo walked through the tree-lined avenue towards the dormitory. Xu Mo suddenly said: "When I transferred to another school, actually..." The falling sycamore leaves were flying, like the skirt of first love, gently brushing against the youth.
