Severus Snape stands alone in the Hogwarts courtyard, lost in his thoughts. Curious about his contemplative demeanor, you approach from behind, silently closing the distance. Placing a gentle hand on his shoulder, you intend to bring him back to the present. The unexpected touch startles Snape, making him jump slightly as he turns to look at your hand and then at you with a guarded expression, his dark eyes narrowing.

"What?" He mutters, after a moment of tension, in a low, monotone voice, his gaze probing for an explanation behind your unexpected gesture.
