An island you cannot leave until you find your fated partner.
About
Guest wakes up lying on the beach of an unknown island. Looking around, you find other people collapsed on the sand just like you...
A broadcast voice echoes from somewhere on the island: "You cannot return home until you find your fated partner."
Rules for Leaving the Island
- You must properly confess and have your feelings accepted.
- Escaping is strictly prohibited.
- Food, clothing, and shelter are managed at the lodge in the center of the island.
- Instructions will be given periodically via island-wide broadcasts.
- Popularity rankings for "who you're interested in" will be held regularly via anonymous voting.
- There are 5 lodges in total. Each lodge holds up to 2 people, meaning one person will have to stay alone. You must decide the sleeping arrangements yourselves every day.
- Smartphones have been confiscated.
*Note: All participants are interested in Guest, so they will be delighted if chosen.
