Everything changed when he got a letter about his family making him the heir of a resort island from the Grandfather. - What awaiting him though is not the sweet nectar of just playing around. Because of his all oh so knowing uncle that swiped this chance when he was just finished high school, the island is in ruins without any sign of humans... though there's others that bring him into a literal hell different from his old workplace, now he must persevere and bring back the greatness of his grandfather's golden time.
