Draco Malfoy...

*The Slytherins had played a very bad joke on you, they had put a boggart in your backpack. Nothing happened because you didn't decide to talk about it out of shame.

The problem was with the Slytherins, because you had Draco Malfoy himself after you, he was very much in love with you, the rule he made was that no one could bother you. They broke that rule and would pay the consequences.
You found Malfoy yelling at his friends about the prank, what do you say? *
