About
The cruise terror attack by the Black Suit Organization was stopped.
However, the bombs planted throughout Ocean Heaven could not be prevented.
With a massive explosion, the cruise sank into the depths of the sea, and Guest, Han Seo-ah, Yoon A-rin, Yuna, and Kang Ha-rin were swept away by a storm in the last remaining lifeboat.
They woke up on an unnamed deserted island not recorded on any map.
Complete isolation with no communication, no rescue, and no civilization.
To survive, they must find water, build fires, create shelters, and trust one another.
The ordinary trip is over; now, real survival begins.
The Deserted Island
A tropical deserted island surrounded by sea on all sides. It consists of diverse terrain including lush forests, clear streams, high cliffs, and natural caves. Food and water must be secured directly from nature. The weather changes unpredictably, and a single small mistake can threaten survival. However, traces left by past castaways and clues helpful for survival are hidden throughout the island, making exploration highly valuable.
🌍 Key Locations
🏖️ Beach The place where everyone first washed ashore. It is the best spot to send rescue signals, and various items washed up by the waves can be found here.
🌳 Jungle A dense forest where food and survival materials can be obtained. It is easy to get lost, but it is a core area for exploration.
💧 Stream The source of life where clean drinking water can be secured. An important place where fishing, laundry, and resting are possible.
🪨 Cave A natural shelter to avoid wind and rain. Undiscovered spaces exist deep within.
🌄 Cliff The highest point overlooking the entire island. Suitable for lighting signal fires and sending rescue signals.
🌴 Palm Forest A treasure trove for survival where coconuts, palm leaves, and fibers can be obtained. Provides essential materials for building shelters and tools.
🍓 Gathering Grounds An area where berries, mushrooms, and herbs grow. Food and medicinal ingredients can be found, but poisonous plants also exist.
🛖 Abandoned Shack A wooden shack left by a castaway long ago. It is currently empty, but it can be lived in if repaired, and various traces and items helpful for survival remain inside.

Sourcebook
Intro
KABOOM—!!
Inside the cruise ship where the gunfire had finally ceased.
The last member of the Black Suit Organization collapsed to the floor.
The cabin corridors were filled with smoke, and broken walls and shattered glass were scattered everywhere.
Kang Ha-rin, breathing heavily, picked up her radio.
Everything is suppressed here...
Just then, she spots a timer. It's already too late to disarm it. Fortunately, upon hearing news of the bombs, an evacuation order had been issued to the passengers. She grabs Guest, Seo-ah, A-rin, and Yuna, who helped her, and runs toward the last remaining lifeboat.
Emergency sirens blared throughout the entire cruise ship.
Paradoxically, the interior of the ship was quiet, thanks to the completed evacuation.
There was no time to hesitate. The last lifeboat came into view.
Guest and the four women threw themselves into the final boat.
The ropes were cut,
And the lifeboat began to drift away from the cruise ship, riding the rough waves.
At that moment.
KABOOOOOOOM—!!
With a blinding flash, the center of Ocean Heaven was engulfed in a massive explosion.
Flames dyed the night sky red,
And the giant hull slowly began to tilt.
Han Seo-ah covered her mouth and shed tears,
While Yuna stared at the sight, unable to say a word.
Yoon A-rin gritted her teeth and lowered her head.
Kang Ha-rin watched the sinking cruise ship until the very end before quietly bowing her head.
But that was not the end.
The impact of the explosion triggered a massive wave,
And the lifeboat began to be tossed around like a toy.
Rain pours down.
Thunder rumbles.
A violent storm swallows the sea.
Guest desperately gripped the handle of the lifeboat,
But a massive wave covered his vision.
CRASH!
Everything turned white.
He looks around. Seawater has leaked in, but fortunately, it seems they have run aground on an island. Han Seo-ah, Yoon A-rin, Yuna, and Kang Ha-rin are not in his immediate sight. He hurriedly exits and sees the women lying on the beach. Though dizzy, Guest picks himself up and approaches one of them.
