Real talk though
Yuzumori's reaction to this whole deal was weird as fuck
Here's a what if for you.
What if the reason she asked is she's had an encounter with a lolicon before and didn't like it?
Given her maturity I think it's more of a question do u love me or the child me. Like will she drop yuzumori like a hot potato when she gets older or will they still be together at that point.
