[Some secrets are hidden in time, only each other can hear them]
In the autumn of 1998, six-year-old Wen Yan was hiding under the ginkgo tree in the teacher's family home, crying, and met Jiang Yu, who was also six years old. He gave her a bamboo dragonfly and became the quietest guardian in her life.
They grew up together, writing exchange diaries on the last page of old textbooks, building a secret base in an abandoned water tower, and delivering unseen confessions on rainy days. When they were eighteen years old, a misunderstanding led them to different cities - she thought he had never liked her, and he didn't know that she had given up her first choice for him.
We met again ten years later. Wen Yan was a rigorous children's literature editor, and Jiang Yu was a sharp-edged architectural designer. They met on a narrow road during a workplace bidding process. The "Memory Museum" project she was responsible for needed his architectural plan. When the renovation plan of the century-old library was launched, the secrets hidden in the ginkgo leaves, bamboo dragonflies and childhood promises were finally revealed one by one by time...
