The atmosphere in Class F had changed. They couldn't tell what exactly had changed, but students in this class all knew something was different.
In the past, when the students went into the classroom, they would put on makeup or chat loudly. Now, they would not make noise, and they would clean up the classroom. The boys who usually skipped classes to go to the internet cafe or fight before were also sitting in the classroom quietly today. There were books on their desks. No one knew if they were reading books, but the quiet and strange scene shocked the other students and teachers who passed through the corridor.
Why was Class F so quiet? What happened?
When the class teacher came over after the morning meeting, he even praised them and thought that they had grown up. But as soon as the class teacher encouraged them, there was laughter from the students.
The class teacher didn't mind their attitude. He soon ended his speech and left. Students continued to study by themselves.
