I'm very aware that they're not, I just couldn't see what the trigger was for that trauma until pretty much just now cause I didn't notice the band leader said the same thing Sato did
I think she saying he should never play piano again and should never played the piano in the show was really but really bad thing talk to him even if she reasons are valid.
One thing everyone needs to remember is that words has a big impact for a person and can make a person being traumatized for a whole life if he did not get any support.
I think they will meet again and both will apologize to each other,Kurose for mess up in the performance and Sato for the harsh words that she should not have said.
