Li Xiaoxia and Lu Zihang, childhood sweethearts in the military compound, were separated three times due to family changes and growing pains. The unsuccessful conveying of feelings through postcards in junior high school, the misunderstanding caused by the misplaced diary after the high school reunion, and the mistakes in the college entrance examination application finally completed the time and space closed loop on Peking University Ginkgo Avenue. The concept of organic chemistry is used to deconstruct the emotional trajectory. The difference in boiling points of isomers metaphors the dislocation of youth, while the same melting point symbolizes the eternal fit after going round and round.
Purpose: Use the unique romantic aesthetics of science students to deconstruct the dislocation and growth of adolescence and reveal that true emotional connections are like isomers - even if the paths are different, they will eventually meet at the same melting point. Through the time-space closed loop of ginkgo leaf specimens, starry sky projectors and other props, the dialectical relationship between memory preservation and self-expression is explored, and the belief that "true love will never get lost" is conveyed.
