After flunking his Tokyo University entrance exams for the second time, Keitaro Urashima is left without a job or education, making him appear as a lazy bum. To compound his problems, his parents have evicted him from their home. Luckily, his grandmother is the owner of the luxurious Hinata Lodge and hires Keitaro to oversee it. However, he is oblivious to the fact that the lodge caters exclusively to female residents, and he is the only male occupant! Although most men would jump at the opportunity to live with five attractive women, Keitaro must be cautious as this work may be the death of him.
