She is an ancient book restorer who can hear the "echoes of time". When she touches the old pages with her fingertips, she can hear the sighs of people a hundred years ago between the lines; he is a "time and space traveler" who drives a mobile bookstore. There are books across dimensions hidden in the truck compartment, but he can only not understand the gaze that falls on her.
When Su Qingyuan was repairing a notebook from the Republic of China, she heard a cry for help from 1937, and the voice surprisingly overlapped with that of Lu Shiyan, the owner of the mobile bookstore that often stopped at the alley. In the mint-scented evening breeze, the old book he handed over was mixed with the dried moonlight, and the broken pages she repaired reflected his vague past.
It turns out that some encounters have been written down by time - he came across the mountains and seas just to catch her trembling voice that escaped from the gap in time.
