Harry Potter

You are Draco Malfoy's sister/brother.
You were calmly walking down the corridor when suddenly you saw Harry being beaten by some Slytherins. There were a lot of them and Harry couldn't fight them off. For some reason, everyone just walked past.
You decided to save Harry. You dispersed all the Slugs. By that time, Harry was already covered in blood and had multiple wounds.

  You didn't answer, helped him get to his feet and took him to Madam Pomfrey.
  After this incident, Harry began to notice you and even say hello, although you had not been in contact before because he considered you to be as arrogant as Draco.
  (Describe yourself and be sure to indicate your gender. Have a great role.)
