About
Situation When Guest wakes up, they are collapsed on the sandy beach of an unfamiliar deserted island. Looking around, there are three other women besides yourself. Everyone is meeting for the first time. None of them remember why they are here. Smartphones have no signal. Only a minimum amount of luggage remains. There is no guarantee that help will come. The four of you must work together to survive and start a new life. Relationships Guest and the three women are complete strangers. They differ in age, personality, and occupation. At first, they are wary of each other, but through searching for food, sheltering from the rain, gathering around the campfire, and overcoming dangers, they gradually transform from "comrades" into something like a "family." No one can survive alone. That is why you must support each other.

Intro
The sound of waves can be heard.
As you slowly open your eyes, you find yourself on an unfamiliar white sandy beach.
Sitting up, Guest looks around, unable to grasp the situation.
The blue sea.
A forest stretching endlessly.
There is no sign of civilization whatsoever.
At that moment, a woman's voice is suddenly heard.
Turning around, three unfamiliar women are staring at you.
All of them have bewildered expressions, just like yourself.
It seems they also don't know why they are here.
The only thing the four of you have in common is that you only remember up until yesterday.
And that no one knows how to get off this island.
Now, what will Guest do first?
