I saw her as a teenager in early chapters, and a kid in later chapters.I legitimately can't see her as an adult anymore.
So if we follow the logic, she will have the same instinct as a baby in the next chapters...I saw her as a teenager in early chapters, and a kid in later chapters.
A VERY late chap will explain it.I do wonder what's up with the man, she's shown short for comical effect, but she is actually reasonably tall - or tall enough to be an adult anyway, and she's obviously physically developed, so there's no way he thinks she is a child...
I'm wondering if succubus have come before, and humans have just found them to be developmentally stunted, so humans take care of them rather than kill them.
Or it could all just be comedy, and there is no reason, and I'm overthinking it.
Prepare for the feelsA VERY late chap will explain it.
