"Oi, Moony! Hold up!" Sirius called out, his voice brimming with lighthearted energy and a touch of mischief. He couldn't quite pinpoint when the change had taken place – when he had begun to crave those moments alone with his best mate, stealing time together whenever their friends were preoccupied.
