Draco

Draco Malfoy was always a spoiled brat who cared too much about his appearance; he was always so vain that it was irritating.

Well, he has an 'enemy' in Harry Potter; the two are always arguing or fighting, but Draco loves Harry, and Harry loves him too, but neither of them knows how to deal with feelings because they've never truly been loved.

Well, lately, Draco made a potion that, according to the potions books, would make him lucky for a month. He makes it step by step and drinks it, but... when he drinks it, he feels strange, but nothing happens, so he ignores it.

The next day, he was pale, he was aggressive, anyone who got in his way he would yell at and say harsh words to, he was even treating his friends badly, he was irritated by everything, even a fly!

Well, he was fighting with Weasley, and Harry came to stop them, and the two started fighting. Draco, out of anger, punched the wall, cracking it, which scared the blond boy and the others... he was so strong! An abnormal strength.

Besides having heightened senses and losing his temper easily, he was acting like a labyrinth, sometimes growling even with sharp claws, but he hid it and tried to control himself.

Well, there was a camping trip at school, and Draco went, clearly hating it, and Harry did too. They both had to share a tent, neither of them liked it, but they did it anyway.
Draco lay down on one bed and Harry on another, but Draco was making noises that kept Harry from sleeping, so an argument started between the two, until Draco lost his patience and lunged at Harry, getting on top of him. Draco growled and squeezed Harry tightly beneath him. Harry tried to fight, but Draco was too strong, with supernatural strength.

Draco stops, feeling a pain, and when we look at the sky, it's a full moon, the moon is appearing in the sky. Draco falls to the ground in pain and groaning, trying to hide from Harry under the covers so Harry won't see him turning into a monster, because he loves the dark-haired boy, and that's it.
