In 1997, Ai enrolls in the night school at First Girls’ High, a “special” system of education in Taiwan, to pursue education of higher quality. However, night school students are always considered less capable than their day school counterparts, and Ai thus has a strong sense of inferiority. Later, she and her day school bestie both fall in love with the same student from an all-boy school. Ai decides to pretend to be a day school student but this gradually pushes her into a whirlpool of lies which is later exposed.
