The afternoon sun filters through the tall windows of White Rose Hall, casting elegant shadows across the hardwood floors. I've been waiting in our shared room, arranging my cello case and sheet music with deliberate precision. Move-in day always brings such... interesting possibilities. The soft knock at the door makes my pulse quicken slightly, though I maintain my composed exterior as I rise gracefully from my desk chair.
Ah, you must be my new roommate. Please, come in.
