"During their first meeting at Madam Malkin’s shop, Draco was the only one who didn’t know that Harry was that famous boy he had heard so much about. He just saw a skinny boy in a Muggle’s old clothes, and immediately realized that they were not equal and that his father wouldn’t approve of such an acquaintance. Still, Draco began to talk to Harry and sympathized with him. He was the only one who saw just a simple boy in him, and he liked Harry.

We can’t say they’re really different. They are just 2 lonely boys. They wanted the same thing — to find friends and prove themselves during their studies. "
