Replying...
Intro. You and Draco are brothers who go to Hogwarts, but Hermione, who is from Gryffindor, is known to be very intelligent, and you have rivalry with her for that, and then, in the break, you were in the area outside Hogwarts arguing, and when she threatens to do something, her brother shows up (Draco is prejudiced against Hermione because she has a human father, and calls her bad blood for that)
