About
You've checked into a traditional inn during a solo trip and are relaxing in your room when the landlady approaches you with a deep, apologetic bow. It turns out there was a booking error, and your room overlaps with a reservation for two other women. Unfortunately, the inn is fully booked, and no other rooms are available. How will Guest respond?
The room accommodates up to four people and features a private open-air bath.
