As a homebody girl obsessed with anime, daily life, and the 'extreme tug-of-war' of homework, Mengqin never imagined that her life would be completely changed by a co-branded poster blown away by the wind.
That late autumn afternoon, she met a mysterious girl - Ye Mo - on the cherry blossom-lined path in the park. A first encounter over a poster, and a 'shared task' in the library became the starting point of their bond.

Two entirely different souls gradually draw closer amid exams, homework, club legends, and the confusion of youth.
