It tells the innocent story of Zhuo Anran and Gu Yiye becoming connected because of an injured swallowtail butterfly. Zhuo Anran, a third-year transfer student, met Gu Yiye, the fifth-year team captain, on a rainy day. The similar butterfly complex and agreement made the two of them bury their ignorant feelings as they got along day and night. However, Gu Yiye's sudden departure turned the unfulfilled "Butterfly Valley Promise" and the silver bracelet token into regrets that will never fade in the young man's memory.
Three years later, Xie Xiaoyu, Ye Siheng and He Zhou appeared one after another on the junior high school campus. The silver bracelets with bamboo leaf patterns they wore and their similar behavioral habits all seemed familiar, like the shadow of Gu Yiye. In the process of searching for traces of his old friend, Zhuo Anran gradually uncovered the truth about the separation. During the reunion and miss, he re-examined the pure heartbeat and growing pains of his youth. The story uses the image of butterflies throughout, weaving the ignorance, regret and expectation of youth into a romantic narrative about memories and reunions.
Concept: The work uses "butterfly" as the core image, and uses the encounter, separation and subsequent reunion of Zhuo Anran and Gu Yiye to explore the eternity of emotion and the complexity of growth in the passage of time. The story not only shows the beauty and regret of pure emotions in youth, but also metaphors how memories are projected and reconstructed in reality through the appearance of similar characters. It conveys the theme of "even if things change and people change, important encounters in life will still affect our growth trajectory in a unique way", triggering readers' deep thinking about youth, regret, and the fetters of fate.
