"Siblings with a Mountain Man" begins with a teacher scolding his students for their bad behavior. He scolds the siblings for their excessive attention to their teacher. He tells them that if they are not punished, their behavior will become worse. The teacher tells the students that one day, a group of students suddenly changed and began to study hard. The students' health began to fail, and they began to lose interest in people and things around them, which eventually led them to lose their hair and suffer from severe mental breakdowns.
