Okay, this my first baby in English, really. Please do not hate me for this.
Harry was angry. Actually no, he wasn't angry he was mad and the reason of his madness was standing right before him. Harry felt a really deep need to kill the reason and just run away, but how can he do that? He's in Gryffindor, for God's sake! Harry took a deep breath and tried to calm down.
"Stop smiling, you dumbass! Because of you I have to wear a polo neck until it will be gone!" He said. But the reason was still smiling and clearly having fun!
"Calm down, Potter, it's just a hickie" said Draco and left room with big smile that only Malfoys can use.
