Liu Tan once worked as a tutor for a blind child, but later, the child died in a car accident.
The only relic he had here was the child's composition collection from elementary school. Those essays were not very good, but this was the most precious thing to Liu Tan.
Liu Tan often took it out and read it again, until one time, after reading it, he actually missed the book. And it was a collection of primary school students' compositions?
In that composition, Liu Tan met him, his former deceased student, his only student.
