Shinichi Chiaki is a first class musician whose dream is to play among the elites in Europe. Coming from a distinguished family, he is an infamous perfectionist—not only is he highly critical of himself, but of others as well.

Nevertheless, Shinichi is dismayed to discover that Nodame is his neighbor, and worse, she ends up falling head over heels in love with him.
