This book centers on "Lin Ran" and her friends. It starts in the early autumn of the third year of high school and goes through four major stages: college entrance examination, summer separation, college reunion, and life choices. Five teenagers and girls with different personalities avoid the trivial matters of their parents and teachers, encourage and ridicule each other, and bravely pursue their dreams and love. They experienced misunderstandings, losses, growth and collapse, and unexpected separations, and also gained the past friendship and broken selves amidst the entanglements and tears.
The book uses humorous and fast-paced narration interspersed with the inner monologues of each character, composing a true and vivid song of youth in seemingly simple and trivial daily life.
