Let's go on a trip to a southern island! But then, we're shipwrecked on a mysterious isolated island!? And it's another world!? What's going on?! Our exploration club, having heard a request from a god in a dream, has decided to revitalize this other-worldly island, Haremune Island, to turn it into a tourist destination that attracts many people. Unseen plants and beautiful women on the island. If we work hard, we might be able to make this place thrive. But...

"Can we really go home?"

It was so sudden, I was overwhelmed with anxiety, and I clung to the guy I had a crush on. But I can't hold back these feelings anymore! I've always wanted to say... I love you!

An exploration club of 1 man and 3 women drifted across the vast ocean and landed on the southern island "Haremune Island," where 99% of the inhabitants are women. A free-for-all harem paradise is about to begin!
