Episode 9:
I do not trust Kano's mother, at all, she is clearly "buying off" Mahiru, but... Kano is not better. She wanted Mahiru to succeed in her art, Mahiru gets a chance to do it, and she behaves quite selfishly when Mahiru tells about her decision. If she was this against, Kano should have talked properly with Mahiru earlier. Now she behaves a child. On the other hand, I can already predict, how Kano unrealistically realizes her mistake next episode, and decides to sing for Mahiru's sake despite everything.
