After 20 years of living in a terrible post-apocalyptic world, you find yourself in a miraculously undiscovered bunker, which... is filled with food and beautiful girls. It seems that your life is about to change, but... you can not even imagine how much.
This is a harem comic adventure, where you can become acquainted with four girls - the residents of the bunker. They are surprisingly very pleased with their new guest. Perhaps this is because they’ve never seen anyone from the "surface"? Or is there something else?
