Indeed shy is in the lowest stage of intimacy, when you die or forget to feed it looses intimacy, so that would explain why it ran away. Not explaining why it dropped the fishy however
The thing is Yumera says her pet was neutral with her, if it went shy from her dying then it still wouldn't have ran away, as there are still some points left on the pet.
Aaronock-
Sorry her hunger was neutral her intamacy was shy... maybe awkard i don't remember anymore.
Maiden-
I have Jelly the Poring now so it's ok to a point.
Pandora-
I think the loosing items on pet happened when i got killed by Valkyrie though i can't be certain. I'll repost it again in here if the same thing happens this time but it starting to seem to be more of a string of bad luck then a glitch P:
