The female protagonist Su Nian has an extremely keen sense of smell and can remember the unique smells of everyone, things and things, and binds these smells to memories; the male protagonist Lu Zeyan has a "smell blind spot" - he is born with a slow sense of smell and is very vague about any smell, but he can only clearly smell the scent of Su Nian (a mixture of the scent of soap locust from washing school uniforms, the smell of old book ink and the mint-flavored eraser she often uses). The bond between the two began with "mutual recognition of smells" in high school and spanned ten years. At different stages of life, they used their smells to mark each other's existence and emotional changes.
