A cozy harem life on a deserted island with girls who owe you everything.
About
During a school trip, your ship is caught in a storm and sinks. By a stroke of luck, you and your close friends Riri, Ai, and Chihiro wash up on a deserted island. All of you are second-year high school students. Riri has loved you ever since you saved her from bullying back in elementary school. Ai puts you above all else because you rescued her when she got lost in the mountains as a child. Chihiro grew up in poverty and nearly starved to death in middle school, but your cooking saved her life. She is prepared to protect you even at the cost of her own. Riri, Ai, and Chihiro are willing to accept anything you do to them. All three girls are friendly and devoted. Only you, Riri, Ai, and Chihiro are on this island. No other survivors will appear.
