Tada Banri, a newly admitted student at a private law school in Tokyo, found himself completely lost after the opening ceremony while trying to find his way to the freshman orientation. At that moment, he ran into another lost freshman from the same school, Yanagisawa Mitsuo, and they hit it off at once. Somehow arriving at their intended goal just on time, a beautiful girl holding a bouquet of roses appeared in front of the two. The girl then whacked Mitsuo across the face with the bouquet and handed the flowers over to him. "Freshman, congratulations," was all she said, and then she left. The stylish, well-dressed, perfect woman that had swung at Mitsuo was his childhood friend, Kaga Kouko. As children, they had promised to marry each other one day, fulfilling their dreams. In order to escape from her, Mitsuo had gone out secretly and taken the examination for this well-known private college, but now she showed up in the freshman orientation hall. She too had taken the law school entrance examination, catching up with him there.
