Summary:Keiichi Morisato is an engineering student at Nekomi Tech whose entire romantic life had been confessing to the one girl he kind of liked out and getting rejected. One day, Keiichi was minding his dorm chores, and his final chore was to make a phone call for his senpais. But he dials a wrong number, and got the "Goddess Assistance Agency." Out of nowhere appears the Goddess Belldandy, and she offers him one wish to change his life. ONE wish.
