Not Arrogant

This is my first work for a newbie. I really hope you can comment and help correct errors. Thank you very much. You can also contribute, so I will read all comments. A boy with an ordinary and miserable life experience, a "prodigy" with no talent, why did the temperament of this gentle boy change so much? How does the belief in one's heart view injustice? In a world where strength is respected, one has flesh and blood, lives on, and walks his own path. A semi-cool novel with a slower pace and a female protagonist.
