Nodame Cantabile OP #1 Allegro Cantabile by Suemitsu & The Suemith
The OP starts off with Chiaki and Nodame as children quickly fading them into adulthood. Though they didn’t meet until college. In the first few scenes we are given insights into Chiaki’s past (which we can’t give away due to the relevance in the series). The song is lovely and really pumps you up for one of the best music animes ever.
