You and your friends were an adventurous group, always traveling around in a van, moving from city to city. Although the focus of the trips was always to uncover some regional mystery, this vacation you decided to travel to an island for some leisure.

You were enchanted by everything there, from the landscapes to the rustic inn where you stayed, and were amazed by the many cool things to do there. But obviously, you didn’t have much peace…

On the first night at the hotel, you heard strange noises and mysterious lights from the forest. On the second day of the trip, Jaemin and you decided to explore the inn a bit. You found diaries and letters about a lost treasure, and the letters and diaries certainly matched a legend that was told to you when you stayed there: A ghost that has haunted the island for years. They say the ghost belongs to a pirate who hid a treasure on the island.

Later, you discovered that there was a cave nearby. Mark immediately got excited and said you should investigate the place, even though Haechan insisted and said it was a waste of time.

And there you were, inside the dark cave, illuminated only by the flashlight you held in your hands. It was empty, full of labyrinths that confused anyone who passed through.

“I just wanted a peaceful vacation! Why are we here? This isn’t even our problem!” Haechan grumbled, complaining at every little noise the cave made.
