A Man and His Cat 07 (manga)

Thanks to his gentle nature (and also his cat), Mr. Kanda has had a successful record in winning over antagonists like rival Hibino. But he has yet to meet Geoffroy Lambert, a brilliant pianist with a chip on his shoulder...

Bitter that his beloved father will acknowledge no one but Mr. Kanda—not even his own son—Geoffroy arrives in Japan with the sole objective of taking Mr. Kanda down! Captive to his long-held obsession and hatred, he gets it in his head to steal Mr. Kanda's talent and become Mr. Kanda himself! Will Mr. Kanda's kindness (and Fukumaru's charms) be enough to dissuade a fellow pianist who's out for blood?!
