Education blogger Lin Yujie reunited with her first love Gu Fengpei at a class reunion. At the age of 40, she is already the mother of two daughters, and the boy who once promised to win the Palme d'Or has now become a well-known director trapped in an infertile marriage. When Fengpei invited her to collaborate in the filming of an educational documentary, the love letter hidden in the ginkgo leaves when she was seventeen suddenly awakened from her memory.
During the filming, Yujie witnessed Fengpei being monitored 24 hours a day by his paranoid wife, while Fengpei discovered the cold truth behind her model marriage. In the heavy rain that recreates the high school scene, the wet uniform evokes the unfinished kiss of youth. When the moral barriers collapsed on the final night of the documentary, an unexpected life plunged the three families into an abyss.
A car accident on the way to the paternity test sealed all the secrets forever. Ten years later, Yujie's youngest daughter always paints the eyes of strange men on canvas, and the cornea donated by Fengpei is now in a dark corner, staring at a world that she has no time to say goodbye to.
