this is like that one saying about not being able to find something even though you're trying so hard, yet when you're not actively searching for it, it appears before you.
To be fair, you don't actually have to want the hentai of this to be aware of the endless possibilities generated because someone else out there does want it. I made a joke about expecting hentai of that gyaru manga where she finds a weird dinosaur and starts living with it. I don't want that hentai at all but I know it's possible, maybe even probable.
I'm a little salty for her to not try to look for her grandson since that day, but this chance encounter proved that he moved on too, just like her. So I'm ok (sobs) I guess. I just hope he doesn't become a bitter adult.
