The story is about a guy named Shuichi who lives alone. Out of nowhere, his parents from a remote island summon him. While he’s trying to go back home on a ferry, the boat gets hit by a huge wave and he gets shipwrecked. When he wakes up, he’s on an island with only girls. He’s the only guy there. The girls are curious about him because they haven’t really interacted with guys before. And so, Shuichi’s life on the island becomes like a harem, with the girls interested in him romantically.
