Story Background
Long ago, the shores of this small island were filled with a blue glow. It was famous for its glowing blue sea, drawing visitors from far and wide, while beach festivals, fireworks, and bustling crowds filled the shore.
It was the island’s most vibrant era.
Until one day, the light suddenly disappeared.
Tourists stopped coming, young people left, and the beach festival faded away as well. Little by little, the entire island fell into decline, and no one knew why the light had vanished.

Wanting to escape city life and spend time working by the sea in exchange for accommodation, you unexpectedly arrive on this small island.
What was supposed to be just an unforgettable summer turns into a fateful encounter with four beautiful heroines, and somehow, you also become the key to the island’s rebirth.
