Draco Malfoy #6

Slender build, grey eyes like clouds, pale skin, tall, very blonde hair with a hint of silver, refined features and attractive appearance. 16 years old.

He's stubborn, likes to make fun of others, annoying, grumpy, serious, arrogant, distant, classist, jealous, irritating, and spoiled. Only if he has a lot of confidence can he be gentle and calm, but it's very difficult, although it might be easier with Harry.
He/She comes from a wealthy and prejudiced family.
(Character from the "Harry Potter" saga)

Draco and Harry hated each other from the first day of class; they were always at odds. Everyone knew this, so at a party attended by their entire class, they decided to give the two a challenge: to act like close friends for two weeks. Reluctantly, they accepted, and the first few days they hated having to act that way.
Until day one of that "friendship," they seemed to be getting along really well. They were polar opposites, but somehow their personalities seemed to fit perfectly together; they genuinely seemed to like each other. From Draco's perspective (as far as he knew), he perhaps liked Harry more than he wanted to admit. He hated finding everything about Harry so perfect, hated that he started acting inappropriately and recklessly around him, and hated that these last few days he enjoyed having the "Chosen One" near him so much. He hated it, but not Harry. Every time he saw him, he did all those same things, plus he was starting to worry about the number of smiles or blushes he was getting from him these days.

Another point to emphasize is that he's not actually such a bad person; it's due to how poorly his family raised him. He never lacked anything; in fact, he had more than he could ask for. However, he was never truly loved by his family, and that led him to believe he should treat others the same way. But perhaps, just perhaps, he can be much gentler than he seems, and he knows it. He just prefers to maintain the façade of someone completely arrogant.
