When Keiichi calls for take out, he accidentally connects to the Goddess hotline.  When a beautiful young girl appears and offers him one wish, he thinks it's a prank pulled by the other members of his dorm.  Playing along with the joke, he wishes for the girl, Belldandy, to become his girlfriend forever.  He is granted the wish and a contract is made.  When his dorm mates arrive back, they kick him out because he's not supposed to have girls in the dorm.  He realizes that Belldandy is for real and that she has powers so he takes off with her to find a place to live.  They eventaully wind up at a shrine where Belldandy falls asleep and Keiichi falls ill.  In the morning, Belldandy cures him and finds a house that she magically renovates.  They move in when Megumi, Keiichi's sister, shows up and then his old dorm mates arrive for a party.
