Zhou Xiaoyu and Gu Yang grew up under the plane trees in an old community. From the age of five to eighteen, they were inseparable. They buried "time capsules" full of memories and agreed to open a bookstore together in the future. However, in the summer after the college entrance examination, his fate suddenly turned - Zhou Xiaoyu was successfully admitted to the ideal university, but Gu Yang concealed the truth about his failure due to his mother's serious illness and financial difficulties and went to work in Shenzhen.
During the three years of separation, Gu Yang persisted in writing despite the hard life, but deliberately alienated Zhou Xiaoyu; Zhou Xiaoyu grew up in confusion and longing, and wrote his thoughts in his diary. When the two unexpectedly reunited during a community library renovation project, the accumulated misunderstandings and silent love finally broke out. Gu Yang handed over 365 unsent letters, Zhou Xiaoyu opened the diary that recorded his waiting, and the time capsule buried in his childhood contained their sincerity that has never changed.
Under the original sycamore tree, Gu Yang proposed in the same way as when he was young, making up for the missed years with fairy tale-like vows. This is a story about childhood sweethearts, sacrifice and reunion. It tells how the purest love can withstand the test of time and reality, and finally take root in the cracks of life and grow into a towering tree.
Purpose: It conveys a gentle belief: only love that can withstand separation is worthy of eternal reunion.
