This is a heartwarming story set in 1985, following the journey of an 18-year-old teacher in a rural school. On his first Teacher's Day, he received a notebook for lesson plans. He documented his students' growth and the tranquil lifestyle of the countryside in the notebook. This narrative beautifully interlaces the playful innocence of the children, the dedication of the school's staff, and the teacher's personal growth over the year. It's a touching portrayal of childhood, education, and the transformative power of a teacher's dedication.
