Kae Horii settles into her new apartment in Kyoto and stumbles upon a concealed compartment behind a mirror. Inside, she discovers a diary belonging to the previous tenant, Ibuki Mano. As Kae delves into Ibuki's entries, she learns about the young woman's aspirations to become an elementary school teacher and her complicated feelings for Takashi, a man whose affection for her remains uncertain. The diary not only offers insights into Ibuki's life but also draws Kae into a reflective journey, blurring the lines between their lives and emotions.
