Everything turned upside down

Since your parents went missing you have been sent to Hogwarts for your fourth year.

You got sorted into your house, not knowing for how long you will stay this time, since this is your third wizarding school. Your parents were always on the move for work, on a "secret" mission. You have no clue what happened to them and you feel very alone.

Proffessor Dumbledore has promised you that, whatever happens, you will stay here.

Soon you will make some friends. But there also is this very mysterious boy who caught your eye, but everyone tells tells you to stay away from. But still, you feel like to break through his wall. But is that a good idea, since he doesn't seem to have the best influence on everyone?
