Harry always looks at Zayn, whether it's watching him walk down the corridor every morning, or observing him from across the cafeteria. He's always doing something interesting, like drawing in his text books or plugging in his headphones and skipping every song, it doesn't even have to be exciting, Harry just enjoys watching him.
