Harry Potter: The Heartthrob with an Angel's Face

Also known as: HP: But the Beloved-by-All Protagonist Is Ruthless A quick warning: The protagonist is cold-blooded and probably unfriendly to everyone. He is an absolute egoist. A devil dressed in an angel’s skin. But when he looks so much like an angel, how could he possibly be a devil? Perhaps the world was wrong from the start. Angels are born righteous, and perhaps the harm he causes is simply unavoidable. No one wants to peel away the devil’s disguise, because his beautiful exterior makes them deny the filth within. He lives only for his own interests. P.S. He’s a genuinely evil character, and it’ll most likely have no pairing. (I don’t have an outline yet, so I’m just writing whatever… I might not finish it.)
