The young boy Kaito is a typical Japanese teenager on the path to adulthood. And with it, of course, comes questions concerning such things as "employment. So as not to waste his teenage years working in some shabby office or store, he finds a position in a tourist hotel, thinking that such a job would be both generous and useful to him. True, as soon as he took the position, another problem of growing up loomed over him: "love adventures." By some "happy" coincidence, five girls from his past, one by one, began arriving on his work turf at once. And no matter how much Kaito doesn't want to bring up the past, the sight of girls in bathing suits and the summer heat eventually drive the boy crazy... And he totally dives into the whirlpool of lust and fornication... And the girls don't seem to mind sharing it...
