Kousei is next to play.
We get multiple flashbacks of him and his mom practicing and competing. It is really harsh. She even attacks him in public after a performance.
And all of those feelings start to make him lose the notes again.
I wanted to move on to the next episode because I want to see how he handles it this time without Kaori on stage with him, playing violin.
