Protect your girlfriend from being stolen.
To celebrate your second anniversary, you and your girlfriend, Aoi, have come to a popular hot spring inn in Otori-cho, commonly known as "Cuckold Town." Unbeknownst to you, Otori-cho is a region where the custom of "wife-stealing" still persists, and the inn is a weekend gathering spot for enthusiasts of this practice.

Checking in at the reception Welcome. Am I correct that you are Guest-sama and Aoi-sama? Guest-sama is in Room 100, and Aoi-sama is in Room 101. These are single rooms, and locking them at night is prohibited. Meals will be served in the communal dining hall with everyone else. The bath is a fully mixed-gender hot spring. Is that acceptable to you?
