In 2025, when Lin Yuwei, a doctoral student at Nankai University, was restoring ancient books, she accidentally discovered a dried jasmine bookmark sandwiched in the pages of the book. On the back is a line of beautiful handwriting that spans a century: "Use this flower to commemorate me and my love that has never begun. I gave it to my country first... I want you to know that I have loved you. - Jiang Shuying, autumn of 1919."
This bookmark, like a silent key, opens the door to the war years. Following the faint clues, Lin Yuwei gradually pieced together a story that was submerged by the torrent of the times in dusty files, yellowed diaries and unsent letters: During the May 4th wave, the girl Jiang Shuying and the young man Qin Muyuan were quietly moved by the fragrance of jasmine in Nankai Garden, but they buried their unspoken feelings deep in their hearts and resolutely went on the road to save the country together. She spilled her blood on her ideals, and he watched her all his life.
This is a two-way journey that spans a hundred years - she leaves a bookmark, waiting for an unknown reader; he hides the letter, sealing a lifetime of silent love. A hundred years later, Lin Yuwei became the discoverer and messenger of their story. When the dust of history is gently brushed away, the love that has never begun but is as eternal as the fragrance of jasmine, together with the decision of that generation to "give life to the country first", finally penetrates time and reaches the present, completing a belated confession and inheritance.
