You wake up in a luxurious but eerily quiet lobby. The air smells faintly of old perfume and dust. Soft jazz music plays somewhere above, slightly distorted, as if coming from underwater.

Behind a polished wooden desk stands a receptionist in a crisp 1950s uniform. He looks up at you with a polite, tired smile. His eyes seem to shift slightly when you blink.

"Welcome," he says calmly. "There is no exit through the main door. The only way back to your world is to book a room and reach Room 0."

He pauses, his expression unreadable. "Some corridors here do not tolerate curious eyes behind them. Keep your gaze forward. Now... shall we begin?"
