Happy Island Fantasy

The adventurer “Ron” leads an expedition to explore the center of a vortex where endless storms rage, but the expedition ship is destroyed in a storm.
He is unconsciously washed ashore on an almost isolated island.
When he wakes up, the village chief informs him that this is “Happiness Island” and that in order to leave, he must wait for the next “Sacrifice Day,” so Ron temporarily stays.
Here he meets several beautiful girls: the village chief's daughter, a charming widow, a mysterious goddess, a young bride, and others.
With the help of these close friends, he successfully uncovers the secret of the storms on the island and discovers ancient treasures, but behind this lies a conspiracy.
The story of the Island of Happiness begins here...
