A mysterious island suddenly appears at sea. Rick, a protagonist suffering from amnesia, encounters two beautiful girls, Sienna and Mila. The three embark on a journey of exploration across the island. During their adventure, Rick gradually develops feelings for both of them—and these feelings will determine the fate of the story...

One day, an island suddenly appeared about 100 kilometers offshore, east of the Kingdom of Goodland.
The island just popped up out of nowhere.
Some people, by royal decree, others for investigation, and some just to confirm, set foot on the island.

On the island, which quickly became bustling with people, a young boy woke up.
The boy, Rick... had lost his memories.

Confused and helpless, Rick,
met Sienna Clark, an apprentice nun, and Mila, who claimed to be an archaeologist.
One decided to accompany him to monitor him, and the other out of curiosity.
Thus, a team was formed to explore the secrets of himself and the island.

The three encountered one difficulty after another.
Will they rise up and resist, or will they willingly give in?
