Since Hino has started to play the violin without the magic, it sounds horrible. She tries her best and keeps on practicing. Moreover, it has been the talk of the school. Hihara is greatly affected of what is happening and Hino tries to cheer him up. Hihara also tells her his story about the time he quit track team to play the trumpet.
No the teacher is more likely just like Hino 25 years ago but he probably never continued playing like Hino has done, and the one he had loved then probably had gone off to continue playing music. that's how i see it.I'm gonna miss Yunoki
They said that the "violin romance" was 25 years ago. So ... their teacher is in his 40s? He's not drawn anything like their parents! What, is *he* magic, too??
