When Lin Ye was at a low point, he broke into the "Midnight Pawn Shop", mistakenly believing that pawn time could make up for regrets, but he found real salvation in the process of running a used bookstore with Su Xiao.
The bookstore has become a container for time stories: Grandma Xiaotang's cross-generational love letters, Grandpa Chen's rural teaching diary, late replies spanning fifty years, and old books drifting across mountains and seas are all circulating here.
From two people staying together to being guarded by three generations, from the four-season flowers and leaves in glass jars to the time capsule under the old locust tree, Lin Ye finally understands the words of the pawnshop old man - the most precious thing is never the "if" of pawn, but holding on to the people around you, and living every moment into a story worth collecting.
