Hinomori's mother is SO untrustworthy. I am liking the story so far, but damn, she's so evil and stupid. She went and deceived her own daughter. She couldn't even wait ONE DAY to let the AGREED DEADLINE finish before booking a flight. She lost all reason and reality by ignoring the achievements her daughter did in TWO WEEKS WITH SINGING compared to YEARS OF PIANOING. Bitch this is why you're single.
I get that some of us are hoping that she wouldn't interfere with Tsunaguoto anymore, but with how her character is, I'm afraid this wouldn't be the last time we're gonna have issues with her. This feels a bit like convenient plot writing from the author as well, but I'll let that slide for now.
