Enjoy Summer Maximum

It's summer! The beach! A deserted island! A summer trip I won in a shopping street raffle, to a deserted island resort run by just one old man. Not even a hint of allure... "I'm hopeless with girls so this trip is perfectly tailored for me," I told myself half-mockingly and braced myself as I arrived on the island - only to be welcomed by an unbelievably beautiful older girl! "My grandpa was suddenly hospitalized... so I'm filling in for him..." The whole summer... just me and her... alone on this isolated island!? As my imagination was about to explode, the situation barreled even further ahead. Between a double-booked reservation and a new helper showing up out of nowhere, things just kept snowballing - and before I knew it, it was just me and four older girls spending the entire summer together on this deserted island. (yikes) What's going to happen to me - me, a guy utterly clueless around girls!?​
