Both have very similar main male characters - Chiaki and Arima are very similar in terms of character, weakness and humour. Kare Kano has more romance straight off the bat whereas Nodame Cantabile has a more realistic take on romance and their relationship. Both couples have problems for similar reasons - although Kare Kano certainly has a darker feel to it.
