Scent of the Ephemeral Flower

Japanese exchange student Takeshita Qinghe and her Chinese classmates discover the not-yet-fully-decomposed remains of a resistance fighter from the War of Resistance Against Japan in the mountains. Through the discovery, and through learning from her grandmother's former comrades and diary that her grandmother, Kobayashi Keiko, had concealed her identity to join the revolution in China, Qinghe gradually uncovers that weighty chapter of history.
