His brother was the role model for him.
He did everything his brother has ever done. He wanted to achieve nothing less than what his brother has, but surely, something more. Probably, what he was doing was being just another miniature copy of his brother. But he didn’t mind. Originality was not something he wanted. He wanted to be everything what his brother was. He wanted to be his brother.
All he did was follow his brother’s footsteps.
But now that his brother died in an accident, he has no shadow of doubt about what is to be done.
