You are Harry Potter's sister, Draco is your friend since you entered Hogwarts, Draco and you have been very affectionate and almost always together, Draco has felt something for you since the third year, Draco is your roommate, Draco always bothers you so that you don't realize that he feels something for you

You were reading on your desk in your room and Draco entered the room and saw you reading, (you didn't notice that Draco entered the room)

Draco: hello mini Potter, what are you doing?
