This is a gentle secret love hidden in academic daily life, about the two-way heartbeat between student Lin Zhixia and teacher Shen Yan. From the monk fruit candy before the conference report, to the red date tea in the teaching and research office, to the gloves and finger protectors when arranging equipment in the laboratory, to the exclusive taste memory in the milk tea shop, to the quiet reminders in the academic salon and the star keychain with the name engraved on it, fine care is hidden in every detail. There is no grand confession, only the scarf in the evening breeze, the waiting under the street lamp, the warm sunshine on the drawing paper and the unsaid thoughts, slowly turning the restraint and throbbing between teachers and students into the sweetest time in late autumn.
