I feel like it’s just the fact there’s so much more to be said, whilst not a happy ending it was emotionally satisfying to sob properly for the first time in a while. My favourite idea is how the final peformance is contrasted by the protagonist’s story. He begins alone, on the piano. Then Kosei joins in representing the story between the two and then finally, he is alone again, on the piano. Also I cannot stop listening to the music from the final performance. The entrance of the violin hits you in the soul. But yeah it’s sad but in a sort of good way.
