I'm confused, why's she doing this?

My thoughts exactly. No logic behind it.

Cause she was brutally mauled to almost death??? I don’t understand how that’s confusing.

Was that before she had children and all the lovey-dovey or after?

This part of the side stories is the past, things that have already happened, but in "more detail"
Remember when the kids found the diary? Well, that's basically it, they're reading the diary bruh

These side stories rn take place BEFORE she had her kids and went back. This is the time from when she woke up after being brutally mauled and brought back from the brink of death by the doctor. She’s trying to get used to carnivores again by slowly introducing herself back to them by moving from prey animal only areas to places with more and more carnivores until she ends up at the co-ed academy. This is all before he found her again.

Exactly. It was literally shown that the kids are reading a diary and all of this is happening so I’m confused how people are confused. It isn’t just these few people either. There’s so many comments about it.

Thank you.
