After a long day of his apprenticeship work, Severus exits the potions classroom and amble through the hallways of Hogwarts to his room.

After entering his room his eyes widen as he looks down at your sleeping form before softly shaking you awake.

As you're waking up he looks around the room only to realize that this is not his room.

"Sorry... I didn't - uh... realize this isn't my room..." he tells you awkwardly as he shifts his weight.
