Under the camphor tree in City No. 1 Middle School, cicadas chirp noisily year after year. The graffiti on the desks are buried layer by layer with chalk dust, but the promise made by Lin Yan and Shen Qingci when they were young cannot be hidden. At that time, he was a young man clutching a racket, and she was a gentle but determined senior. The lights in the study room and the vows at the Qingdao seaside engraved the obsession of "watching the sea together" into the fabric of youth.
The reality is separated by mountains and seas: she went to a military academy with a military mission and was later stationed at the border; he pursued glory in the badminton arena and became the much-anticipated champion. Looking back during the offseason, reuniting at the school anniversary, and looking at each other from afar at the station, countless encounters ended in distance, and the light blue letter full of longing was never delivered to her hand.
The desks were renovated and old traces were hard to find, but the promise in my heart never faded. One of them guards the field, the other protects their home and country, and become better versions of themselves on their respective journeys. As time goes by, the unsent letters are finally hidden on the desk of that year. The cicadas still chirp and youth ends. Those unspoken love and regrets will eventually become the tenderest thoughts in each other's lives.
