They had potions after lunch, and Draco was genuinely impressed with how well Harry had been doing in the subject. For his part, Harry had no interest in the subject matter itself. He just liked how brightly Draco smiled at him when he did something well. It was enough for him to get passing marks on his solo assignments, at the bare minimum. Draco had no issue brushing his hand against Harry’s to tell him a correction or give him some advice, which Harry was immensely grateful for.
