Hmmm... how much friendship level do you have for Hanae right now? You can check this in the bedroom. Also, have you unlocked her special item in your bedroom? This could be another bug.
I don't think I've gotten that far. Eventually she started interacting again, and I was able to do a massage and +5 friendship something like three times in a row before she stopped for the day. She seems to be back to normal now.
I see. Can you tell me the friendship level while the bug was experienced though? I’d like to check it out and maybe try to see what might have caused it.
