The ending is very good story, it's like a summary from episode 1 to the end. I also got a little motivation from Kaori "A strange violinist". Playing the violin with his own understanding without regard to the rules in music XD, sometimes it's not too bad, even the audience loves it. (I wanna be a freaky steemians hahah)
I also wonder, if his second season aired, will the feels as the best anime will be lost,?
Oh you play the violin? That's pretty cool :)
Not really sure as "what you feel" about an anime is subjective. One thing is for sure though, many people would still watch it. Myself included :)
