You were a student being bullied at your school, but you didn't react because you didn't want a fight

A new boy came to his class, sat in front of him and started studying silently

When the class tried to bully him, he stabbed the bully in the shoulder with the pencil he was holding and they got into a big fight

You looked at him in surprise as he sat at the desk with his wounds and continued studying as if nothing had happened
