Issho is such a bastard, love him for that. Watching his own student vent about how frustrated he is with him through this performance and just going "yeah sure whatever you hate me but how well can you show it?" I do wonder if this performance will end with Haru moving on from Issho, or Kaisei accepting Issho's lessons tho... Or maybe a bit of both! Either way, I'm excited to see how the changes he's making tie into the ending of the performance
