A boy in the 6th grade of elementary school, this year he will spend another year at his grandma and grandpa's house in the countryside. This year, he will be spending time at his grandparents' house in the countryside, taking a traditional Japanese bath, picking wildflowers, and spinning yarn. Through days unique to the countryside, which cannot be experienced in the city, the film depicts the emotional growth from a child to a boy and his relationship with his grandparents of a different generation. The book is somewhat nostalgic and reminds us of the embarrassment of adolescence that we have all felt!
