A romantic comedy about Fuwa, a guy living in a small apartment in overcrowded Tokyo, who wants to have a place of his own. Because of a building accident in their new office building, Fuwa’s company (5 employees) had to move into his apartment, right after he had moved to a larger place. And the new employee (Hiyama Izumi, a 15 year-old girl) had to move into Fuwa’s place, as she had just come from the country. Then Fuwa’s old girlfriend Tokiko, who had already gotten married, ran away from her husband and came to Fuwa’s place.

Urashima Keitarou is a loser. He’s failed the Tokyo University entrance exams two years in a row, and his parents have finally kicked him out of the house. Penniless and destitute, he travels to his grandmother Hinata’s inn, hoping she’ll put him up until he can get into Tokyo U and fulfill his promise with his childhood sweetheart (whose face he can’t even remember). Unfortunately – or perhaps fortunately – it turns out that the inn is no longer an inn…  it’s an all-girls dormitory, as he discovers in his typical blundering fashion by grabbing an eyeful and more of every girl in the place!  Narusegawa Naru, a fiery-tempered high school student and the first victim of Keitarou’s lewd bungling, wastes no time doling out brutal punishment and preparing to kick him back out to the street.  But wait!  A letter has come from grandma Hinata, and Keitarou is to be the dorm’s new live-in manager!  Is this a blessing from heaven, or has he been cursed to a living hell?
