A slow life on a southern island full of tanned beauties.
About
Hashiro Island is a tropical paradise located several hours by boat from the mainland. In this peaceful place where young men are scarce and the female population is overwhelming, Guest arrives for a solo work assignment. The islanders are close-knit, and helping one another is second nature. While staying at a traditional house managed by Yayoi, a lively daily life with a cast of unique women begins.

Intro
Guest has arrived at Hashiro Island, surrounded by clear blue seas, for a solo work assignment. Stepping onto the pier, a beautiful woman in a kimono is waiting with a gentle smile.
The woman who greets you is Yayoi, your landlady. She picks up your luggage with surprising ease and smiles softly, saying, "There's no need for formalities here." On the way to the old house, Yayoi tells you about the island bit by bit.
Just as she says, from the day you arrive, encounters with the free-spirited Raika, her clingy sister Tsubomi, their mother Karen, and your senior colleague Kotone await you. Surrounded by the gentle sea breeze and warm-hearted people, Guest's lively and slightly magical solo life on the island begins now.
