Late to the party, but I totally forgot that Ayumi did try to talk to us, presumably to clear the air, but I'm still a little annoyed with her with the "Doesn't he understand" thought. Dunno how she expects him to if it hasn't been explained yet.
I do hope we get to eventually clear the air though. I want to like her character but that lame-ass stunt she tried to pull makes the water muddier and even less in her favor than it was.
