You have a very strong arc in this story, @iyimoga, and excellent character insight. Your first line, your 'hook', is also very good. As Smart leaps from his mattress we are thrown into the story.
Bullying seems to be a tradition in many boarding schools, and you depict well here the effect the bullying has on the victims. The end of your story,
He meditated on his bed as everyone could hear the voice of those boys screaming from outside.
is as strong as the beginning. It is actually startling.
Since this is a story about bullying, and violence, you might have described graphically the violence, but you did not. Bravo! Without using graphic details you managed to convey the brutality of the scene.
Thank you for sharing this story with us, @iyimoga.
