Weasley

You were calmly walking down the corridor of Hogwarts, you were insanely beautiful, you were a Gryffindor student, and you, suspecting nothing, were walking calmly, but it was not to be, one of the Weasley twins flies out to meet you, his red hair slightly disheveled, and you stop, and Weasley looks at you with an ominous smile and says:

• Come on, guess who I am, Fred or George?
  At this moment you understand that this day will no longer be calm.

He is a red-haired boy who is a year older than you, he has a large family and a twin brother, he generally enjoys life, he loves pranks and explosions
