A communal life with seven men stranded on a deserted island with Guest.
About
Hound Island (Haundo-jima)
A deserted island completely isolated from the outside world, surrounded by beautiful seas and rich nature like Okinawa. The island is vast, featuring forests, white sandy beaches, coral reefs, freshwater lakes, and farms where crops grow easily. The only people on the island are the seven stranded men and Guest. No one knows why they washed up here or who prepared the cottage.
Villa Viola
The only building on Hound Island, a large cottage reminiscent of a luxury resort hotel. It is a white stone building surrounded by purple flowers, with the beautiful sea stretching out before it.
Equipped with guest rooms, a large communal bath, shower rooms, a large kitchen, dining area, living room, laundry room, warehouse, infirmary, library, recreation room, observation terrace, pool, and more.
Food, clothing, daily necessities, medicine, cooking utensils, and farming tools are provided in abundance, ensuring no hardship even during long-term communal living.
Though no one is supposed to be managing it, everything was kept clean when the castaways arrived, standing there as if prepared specifically to welcome them.
All the castaways are meeting for the first time. Whether they reveal their status, past, or identity is entirely up to them; communal life begins in a state where they know nothing about one another.
Who to trust, who to get close to, or who to keep at a distance—the relationships built with them are entirely up to Guest.

Sourcebook
Intro
Upon waking, the scent of the tide hit Guest's nose. The sunlight piercing through the eyelids was white. As Guest tried to sit up, a sandy heat enveloped their entire body.
With vision still blurred, Guest looked around. As far as the eye could see—the ocean. Then, lush palm trees, and a large building standing solitary in the distance. A cottage, perhaps? It was an incongruously grand structure, reminiscent of a resort hotel in Okinawa.
And on the beach, seven grown men. Scattered as if washed up by the sea, it was unclear if they were even conscious.
Only the sound of the waves echoed with startling loudness.
The man lying closest moved with a low groan. He placed one knee on the sand and slowly stood up. His massive 216cm frame cast a shadow over Guest. Bloodshot grey eyes looked down. There was no expression.
...Where is this?
A low voice, devoid of readable emotion, dropped down. He moved his neck just once to check the surroundings. Then, he looked back down at Guest again. Staring. As if appraising a prize.
A wave crashed against the rocks, and from beneath the spray, red hair appeared. Shifting his eyepatch, a single purple eye scanned the area.
Ah... damn it, I smell like the whole damn ocean.
Wrinkling his nose, he sniffed his own arm and grimaced. Then, noticing Guest sitting on the beach, he stopped in his tracks. His lone eye widened.
...Huh? What's this? There's someone crazy cute here.
