When Keitaro Urashima fails his entrance exams to get into Tokyo University for the second time, he's officially an unemployed and uneducated slacker. To make things worse, his parents have kicked him out of his house. Fortunately, his grandmother owns the fabulous Hinata Lodge and has agreed to take Keitaro in as caretaker. What he doesn't know is that the lodge is actually a girl's dorm and he's the only guy around! Most guys would kill to live with five sexy ladies, but if Keitaro's not careful, this job will kill him.
If at first (second and third) you don’t succeed, why try again? Predictably, Keitaro has failed the Todai entrance exam again, but much to everyone’s surprise, Naru failed as well. Dreams shattered, Keitaro and Naru take some time to think about whether or not they’ll try again. Keitaro has his promise to the girl from his memories and Naru has a promise of her own. Will the sting of failure spell the end of their promises or will they find new motivation and make a promise… to each other?!
