On October 17, 2019, Lin Zhixia left a drawing in the "Shiguang" bookstore. Little did she know that the drawing would be picked up by a stranger and a line of pencil written in the lower left corner - "This place should not be defined."
Little did she know that from that day on, that stranger would become the longest footnote in her life.
He attended four of her lectures, read every book she published, and silently helped her shoulder the stress test budget during her most difficult days. It wasn't until the autumn of 2026, when the city station was completed, that she discovered the piece of paper embedded on the display wall, signed "Z. X. 2019.10.17".
It turns out that all coincidences are planned for a long time, and all restraints are deeply affectionate.
This is a story about waiting, building and working together. Spanning seven years and thirty-one chapters, what is strung together by seven copper bookmarks is not a romantic chase, but how two independent souls grow into each other's destination inch by inch in the gaps in the city.
"Don't chase the light, just walk side by side."
Intent: This should not be defined.
